Nik Review – A great review of all Nik Software and the best coupon code. Nik Software Review. Try the Nik Collection for Free! In March of 2. 01. Google announced that all Nik Software plug- ins would be bundled together into the Nik Collection for just $1. The bundle includes HDR Efex Pro 2, Color Efex Pro 4, Silver Efex Pro 2, Viveza 2, Sharpener Pro 3 and Dfine 2. Note: Google has discontinued all discount coupon codes for Nik Software. Nik Software Review. All the Nik software is good and fun to use. The “fun to use” is perhaps a strange thing to say in a review, but many of you already know that my reviews are often atypical. I tend to be short and sweet in these reviews, just quickly giving my opinions and providing examples of a few of the options that I use. And, frankly, I think editing photos is quite fun, so it’s always nice to have post- processing software that makes me smile. Another aspect of my reviews is they are chock full of huge screen shots. В I learn by example, and maybe you do too? В This selection of shots should give you a pretty good idea of the range of the software. Now, there are SEVERAL products in the Nik Software suite. This review will describe four of them. I will spend more time on some than others. Here are the ones I will discuss, in order of the time I will spend on them: Color Efex Pro – A very cool package that comes with tons of effects. You can even do HDR- like effects with one of them. Silver Efex Pro – For incredible and easy B& W conversion. Think B& W conversion sounds boring? It isn’t with this thing…Sharpener Pro – Some very nice algorithms for making your photos pop. Viveza В 2 – Slick software for doing localized control of things like contrast and saturation. Complete Collection – Note I am not reviewing this specifically, but this is a package you can get from Nik Software that includes all of the above products together as one. Nik Color Efex Pro. Color Efex Pro is probably the coolest of all the Nik Software products and the one I use the most. В In short, it opens up a new dialog that is filled with a wide variety of filters. В The filters do SO many different things, that it would be silly to list them all out here. В So, instead, I’ll just briefly discuss a few of them. Below, I have a variety of screenshots of some of the effects. В Essentially, what you will easily see is that there are a ton of filters down the lefthand side. В The filter is immediately applied and then there are many sub- options on the right. В The sub- options give each of the filters a much more granular level of control. Because each filter on the left is unique, the sub- options on the right are even more unique. В Each effect on its own has a million possible outcomes based on your sliders on the right. В There is a pretty good example of this in the “Old Photo” screenie below. Now, it is said that too many choices can paralyze people. В I think this can be true. В BUT, if you go into a tool like this with an open mind, and freely surf around some options, I think you will really come away impressed with some of the creative things that will happen to your images. Like anything else, the more you practice, the more you can begin to have a bit of volition in your efforts. One great feature of all the Nik products is that it duplicates the layer for you. Often times, the “effect” may be overdone and you will want to dial it back, or mask with the original image. This allows you to do that. So, what effects do I use most? I hate to list them out here because the list is going to be a bit skewed to where I have the most familiarity, but maybe that is okay. For one, I like “Tonal Contrast” a lot. It does something very similar to HDR, in which it manipulates contrast and light levels on a very small scale. It has it’s own set of sliders as well that enable you to effect how “punchy” the HDR effect is. I have attached a few images of Nik Color Efex Pro “Tonal Contrast” below: Other filters that I use on occasion are “Film Effect”, “Colorize”, “Glamour Glow”, and, “Indian Summer”. I’ve actually tried all of them… and there are many cool ones. So don’t neglect those just because I haven’t given them any screenshot love…This is the before shot. В It is an Argentine artist in her studio. В It was shot at 7. Nik Software Review Try the Nik Collection for Free! In March of 2013 Google announced that all Nik Software plug-ins would be bundled together into the Nik Collection for just $149! The bundle includes HDR Efex Pro 2, Color. The Tonal Contrast options for this shot made it a bit over- baked, but it does show off what it can do. В I dialed it down for the final product. Sub options for Tonal Contrast. This is a zoom- in of the Loupe for the wall texture. You can see how the microcontrast has really made it pop. This is the “Glamor Glow” video. В I don’t really ever use it… it is kinda that “mall shot” effect. The Original Shot right outta the camera (5. After Brilliance/Warmth filter with the slider slid towards the warmth side. Tonal Contrast is one of my favorite and can create an HDR- like effect. The Indian Summer filter gives your photo a warm glow. The Bleach Bypass filter gives quite a dramatic effect. В It’s not very natural, but cool nonetheless. Film Effects can add a nice grain and texture. В You can see that I selected some Kodak film that people probably learn about in film school. The colorize option can give the photo a nice sheen while still maintaining elements of the original color. Here is the “before” shot of a strange area full of crypts in Buenos Aires. The sunshine filter gives a strong but interesting effect. Here is an after version with the “Old Photo” filter turned on. Old Photo has a ton of sub- options on the right.

Explore the basics of Flickr, from posting, organizing, and editing photos to participating in the Flickr community. Last, I’ll show another example of what is possible with “Tonal Contrast”. В This is a huge solar- tracking sculpture. Nik Silver Efex Pro. Wow this thing is cool. Those of you that are regular readers to the blog know that I don’t do a lot of Black & White photography. I have nothing at all against it… I see things in a very vibrant and alive way, and I’ve spent a long time perfecting a technique that helps bring this to photographic reality. However, that doesn’t mean I don’t appreciate a good B& W pick. Yes, Nik Dfine is well respected in the photographic community, as are the other Nik tools and plug-ins. And it is the only one that I know of that makes it easy to set an appropriate amount of sharpening by selecting the. Often times, the default B& W conversion in Photoshop can just be… well, boring. And predictable. Sometimes I take something and convert it to B& W and then look at it and think, “Yeah, well, that’s how I kinda thought it would look”. So, I reluctantly tried Silver Efex Pro, because I expected it to be a slightly improved version of what Photoshop can do — but I was wrong! This is very fun to use and you can get a wide variety of looks. Frankly, I really like the Holga and Pinhole settings on the left, and then tweaking it further on the right. There are many many wonderful options here that can really make a B& W image “alive” and pop off a page. By the way, I have similar information up on the Silver Efex Pro Review. Below, I have put several screenshots of the things I have done with the product, so you can begin to get an idea. Silver Efex Pro enables you to make a choice on the left to give you a basic look, then you can really make it unique on the right. The Antique Photo treatment sounds like a gimmick. В But it came out fairly amazing, don’t ya think? The Holga and Pinhole treatments are two of my favorites. Silver Efex’s B& W options can enable some cool results When it comes to Vignette, the “Stylizing” dropdown has a ton of very easy- to- use options. Nik Sharpener Pro. I have also tried Nik Sharpener Pro 3. It is a fine product. It does exactly what it advertises. I find the sharpening to be a grade better than what is in Photoshop by default. I am always surprised when I use this software! I usually shoot on a rock- steady tripod. This gives my camera incredible sharpness. I zoom into 1. 00% in Photoshop and it looks great to me! And THEN I run Sharpener Pro and I am shocked. It has a little loupe where you can compare the “before and after”… and then I look at what I thought was sharp before and suddenly it looks blurry in comparison. I have posted a few shots below for you. The Output sharpener brought great details. В Check the Loupe on the right (before left / after right)The Raw Presharpener ads some nice details and pop. В Before is on the left and the after is on the right. Viveza 2. Viveza is a very interesting and useful filter. It is also strange! I don’t know who came up with the GUI for this thing, but it is, frankly, weird but cool. Let’s just say it is “cool” after you get the hang of it. I spend a lot of time with various UIs, so I figured it out pretty easily, although I am sure it would be confusing to a lot people. The best way to explain Viveza 2 is that it lets you change one part of a photo without changing another part. These localized changes can be subtle or extreme, based on your preferences. I find that sometimes, especially with my HDR work, that some areas can become oversaturated. Viveza 2 allows me to go in and desaturate one area while leaving the other bits saturated. This is a pretty handy fix. It’s not just Saturation — I should not use that as an example I suppose, because there are so many things you can change. Contrast, Warmth, Shadows, Structure, and more are easy to control. The Viveza 2 UI is the usual Nik look. Sleek. Black. German. Control Points. Nik has this interesting UI way of interacting with your image called “Control Points”. These are little “Dots” (for lack of a better word) that you drop on the part of your photo that you want to mess with. When you click on that “dot”, a local tree of options explodes outward. It’s very cool. The top control allows you to adjust the “radius” of the working area. The other nodes of the tree allow you to change saturation, contrast, brightness, structure, and all those sorts of things. You can see a lot more by zooming in on the screenshots. Dropping control points to fix parts of the image is a simple matter of clicking that control points button in the upper right, and then clicking inside the photo anywhere. A Replacement for Masking. I find that “Masking” in Photoshop is one of the hardest things to teach people. NIK Software Coupon Code - "HDRsoftware. Whoa! This is a really good deal. Last week I learned from The Verge that the Nik Collection by Google has just been discounted by 7. The Nik Complete bundle of plugins normally costs – $4. HDRsoftware. 15 that package is only $1.

Here’s a photo that I used NIK’s HDR Efex Pro 2 on recently in order to help enhance the shot (and this is from a single file – not even the 3 bracketed shots that you’d want to use for proper HDR): It’s honestly not the best example so I’ll be adding some more tutorials soon to show you the real power of NIK’s tools. To see more (and probably much better) results you can get with the plugins found in NIK’s software collection, check out the Flickr search results for NIK processed images. There are a lot of Flickr photographers who use NIK and tag their photos with the software name – which is great for people wanting to learn and draw inspiration from them. Another good place to look is NIK education, which has some excellent tutorials about how to use their different plugins and software packages. Also, if you’re an HDR photographer and would like to write some tutorials for this site on how to use HDR Efex Pro or any of the other software from this package, please get in touch by emailing hdrguide (at) gmail (dot) com – I’d love to have you share your techniques on this site – and help promote your work. Lastly, if you have an i. Phone or Android device you may also want to check out Snapseed, which Google recently made free after acquiring NIK Software. I’ve been using it on my i.

Debounce Code – one post to rule them all. Last month we asked you to send in your debounce code. You didn’t disappoint and it’s time to share the code received. There were some guideline for sending in code so if you don’t see yours here, it probably didn’t follow the rules, sorry. We also tried to weed out code that using delay loops for debounce. These tend to be a poor way to handle inputs because they monopolize the processor. We wanted to add upvote/downvote buttons to each set of code to give some idea of a group consensus on code quality but there’s no good system available for multiple up/down vote widgets on one wordpress page. This results in a huge code dump for any one person to go through. If you’ve got any ideas on how to better organize this let us know: debounce@hackaday. We make no guarantees that this code is safe to use, or that it even works. Test it carefully before using for important tasks. Join us after the break for a whirlwind of code examples.

This report is divided into two parts: Part 1 describes the problem of debouncing and gives emperical data. Part 2 (which you're reading) shows, first, hardware solutions and then software debouncing code. Hardware Debouncers. Figure 1 shows the classic debounce circuit. Two cross- coupled NAND gates form a very simple Set- Reset (SR) latch. The design requires a double- throw switch. Two pull- up resistors generate a logic one for the gates; the switch pulls one of the inputs to ground. The SR latch is a rather funky beast, as confusing to non- EEs as recursion is to, well, just about everyone. With the switch in the position shown the upper gate's output will be a one, regardless of the value of the other input. That and the one created by the bottom pull- up resistor drives the lower NAND to a zero . If the switch moves between contacts, and is for a while suspended in the nether region between terminals, the latch maintains its state because of the looped back zero from the bottom gate. The switch moves a rather long way between contacts. It may bounce around a bit, but will never bang all the way back to the other contact. Thus, the latch's output is guaranteed bounce- free. The circuit suggests an alternative approach, a software version of the same idea. Why not skip the NAND pair and run the two contracts, with pull- ups, directly to input pins on the CPU? Sure, the computer will see plenty of bounciness, but write a trivial bit of code that detects any assertion of either contact. ON. if(switch_lo())state=OFF; switch_hi and switch_lo each reads one of the two throws. Other functions in the program examine variable state to determine the switch's position. This saves two gates but costs one extra input pin on the processor. And, it requires a double- throw switch. But it's the simplest - and most reliable - debounce code possible. The MC1. 40. 43/1. SR flip flops, so might be an attractive solution for debouncing multiple switches. An RC Debouncer. The SR circuit is the most effective of all debouncing approaches. Double- throw switches are bulkier and more expensive than the simpler single- throw versions. An awful lot of us use switches that are plated onto the circuit board, and it's impossible to make DP versions of these. So EEs prefer alternative designs that work with cheap single- throw switches. Though complex circuits using counters and smart logic satisfy our longing for pure digital solutions to all problems, from signal processing to divorce, it's easier and cheaper to exploit the peculiar nature of a resistor- capacitor (RC) network. Charge or discharge a capacitor through a resistor and you'll find the voltage across the cap rises slowly; it doesn't snap to a new value like a sweet little logic circuit. Increase the value of either component and the time lag ("time constant" in EE lingo) increases. Figure 2 shows a typical RC debouncer. A simple circuit, surely, yet one that hides a surprising amount of complexity. Suppose our fearless flipper opens the switch. The voltage across the cap is zero, but it starts to climb at a rate determined by the values of R1, R2 and C. Bouncing contacts pull the voltage down and slow the cap's charge accumulation. If we're very clever in selecting the values of the components the voltage stays below a gate's logic one level till all of the whacking and thudding ceases. If the time constant is too long, of course, the system won't be responsive to fast switch actuations). The gate's output is thus a pristine bounce- free logic level. Now suppose the switch has been open for a while. The cap is fully charged. Snap! The user closes the switch, which discharges the cap through R2. Slowly, again, the voltage drools down and the gate continues to see a logic one at its input for a time. Perhaps the contacts open and close a bit during the bouncing. While open, even if only for short periods, the two resistors start to recharge the cap, reinforcing the logic one to the gate. Again, the clever designer selects component values that guarantee the gate sees a one until the clacking contacts settle. Squalid taverns are filled with grizzled veterans of the bounce wars recounting their circuits and tales of battles in the analog trenches. Most will puzzle over R2, and that's not entirely due to the effects of the cheap booze. The classic RC debouncer doesn't use this resistor, yet it's critically important to getting a thwack- free output from the gate. R2 serves no useful purpose when the switch opens. R1 and C effectively remove those bounces. But strange things can happen when suddenly discharging a capacitor. The early bouncing might be short, lasting microseconds or less. Though a dead short should instantly discharge the cap, there are no pristine conditions in the analog world. The switch has some resistance, as do the wires and PCB tracks that interconnect everything. Every wire is actually a complex circuit at high speeds. You wouldn't think a dull- headed customer flipping the switch a few times a second would be generating high- speed signals, but sub- microsecond bounces, which may have very sharp rise times, have frequency components in the tens of MHz or more. Inductance and stray capacitance raises the impedance (AC resistance) of the closed switch. The cap won't instantly discharge. Worse, depending on the physical arrangement of the components, the input to the gate might go to a logic zero while the voltage across the cap is still one- ish. When the contacts bounce open the gate now sees a one. The output is a train of ones and zeroes - bounces. R2 insures the cap discharges slowly, giving a clean logic level regardless of the storm of bounces. The resistor also limits current flowing through the switch's contacts, so they aren't burned up by a momentary major surge of electrons from the capacitor. Another trick lurks in the design. The inverter cannot be a standard logic gate. TTL, for instance, defines a zero as an input between 0. A one starts at 2. In between is a DMZ which we're required to avoid. Feed 1. 2 volts to such a gate and the output is unpredictable. But this is exactly what will happen as the cap charges and discharges. Instead use a device with "Schmitt Trigger" inputs. These devices have hysteresis; the inputs can dither yet the output remains in a stable, known state. Never run the cap directly to the input on a microprocessor, or to pretty much any I/O device. Few of these have any input hysteresis. Doing The Math. The equation for discharging a cap is: The trick is to select values that insure the cap's voltage stays above Vth, the threshold at which the gate switches, till the switch stops bouncing. It's surprising how many of those derelicts hanging out at the waterfront bars pick an almost random time constant. The boys `n me, we jest figger sumpin like 5 msec". Shortchanging a real analysis starts even a clean- cut engineer down the slippery slope to the wastrel vagabond's life. Most of the switches I examined had bounce times well under 1. Use 2. 0 to be conservative. Rearranging the time constant formula to solve for R (the cost and size of caps vary widely so it's best to select a value for C and then compute R) yields: Though it's an ancient part, the 7. Schmitt Trigger with great input hysteresis. Some AHCT versions have worst case Vthfor a signal going low of 1. Let's try 0. 1 µF for the capacitor since those are small and cheap, and solve for the condition where the switch just closes. The cap discharges through R2. If the power supply is 5 volts (so Vinitialis 5), then R2 is 1. K. Of course, you can't actually buy that kind of resistor, so use 1. K. But. the analysis ignores the gate's input leakage current. A CMOS device like the 7. AHCT1. 4 dribbles about a microamp from the inputs. That 1. 80. K resistor will bias the input up to . Change C to 1 µF and R2 is now 1. K. R1 + R2 controls the cap's charge time, and so sets the debounce period for the condition where the switch opens. The equation for charging is: Vfinal is the final charged value - the 5 volt power supply. Vth is now the worst- case transition point for a high- going signal, which for our 7. AHCT1. 4 a peachy 0. R1 + R2 works out to 1. K. Figure on 8. 2K (a standard part) for R1. The diode is an optional part needed only when the math goes haywire. It's possible, with the wrong sort of gate where the hysteresis voltages assume other values, for the formulas to pop out a value for R1 + R2 which is less than that of R2. In this case the diode forms a short cut that removes R2 from the charging circuit. All of the charge flows through R1. The previous equation still applies, except we have to account for drop across the diode. Change Vfinal to 4. R1 pops out. Be wary of the components' tolerances. Standard resistors are usually ±5%. Capacitors vary wildly - +8. Even small ceramics might vary ±3. Other Thoughts. Don't neglect to account for the closed resistance of oddball switches. Some conductive elastomer devices exceed 2. Two of the elastomer switches I examined didn't bounce at all; their output smoothly ramped from zero to +5 volts. The SR and RC debounce circuits are neither necessary nor effective. Better: run the switch directly into a Schmitt Trigger's input. Never connect an undebounced switch to the clock of a flip- flop. The random bounce hash is sure to confuse the device. A 7. 4HCT7. 4 has a max rise and fall time spec of 6 nsec - easily exceeded by some of the data I acquired from the 1. The 7. 4HC1. 09 requires a minimum clock width of 1. I found pulses shorter than this in my experiments. Some of these parts, like from Philips, have a Schmitt Trigger clock input - it's a much safer part to use when connected to real- world events. Similarly, don't tie undebounced switches, even if Schmitt Triggered, to interrupt inputs on the CPU. Usually the interrupt pin goes to the clock input of an internal flip flop.
