my decisive moment to buy the collection was last December :bang:
I thought I'd use Silver Efex most, but turned out Color Efex tonal contrast has been my most used tool. its bit like Clarity slider in Lightroom, but with more control.
I agree, Color Efex has a range of excellent tools that can be used by a creative photographer and "tonal contrast" is right up there at the top of my list of useful tools. When used carefully (if over-done the image looks like an over-cooked HDR image) it can help pull back a good deal of otherwise lost detail. When followed by application of the Nik Sharpening tool it will really pull out detail you just did not know was there provided of course it WAS there in the first place and the image was properly focused etc. Just be careful not to over do it as this produces an unpleasant "overcooked" look as I said above. I also make a lot of use of "darken/lighten centre" for applying a realistic vignette (it is better than the vignette tool in color efex or any other vignette tool for that matter) and "classic soft focus" which if selectively applied can heighten bokeh effects to the background.
Probably my most used tool, believe it or not, is "Glamour Glow". Unlikely sounding as it is, this tool produces a lovely softening effect to images without making them too soft. So having gone thru a process to sharpen up an image and produce as much detail as possible, effectively I then use a tool which takes it away again (in a controlled fashion). Go figure. It is also wonderful for dramatic effects as it darkens up shadows nicely producing a wonderful "noire" effect (the tool produces a kind of dark glow not a bright one as you might imagine). All of these tools can be applied selectively using the little dot/button "u-point" application thingy or globally. Also, some like glamor glow, can be applied selectively using the slider on the tool. For example, sliding the highlight slider on the tool to the right globally reduces the impact the glamor glow effect has on any highlights in the image. This is often essential as the glow takes detail out of highlights - something you do not usually want. The result is the effect only applies to shadows and mid tones.
Other useful tools include "Contrast only" and "Pro contrast" for alternative contrast adjustment options and the "Brilliance and warmth" tool that allows you to adjust vibrancy and color warmth. One other I find a use for now and then if the camera screws up color balance (or I do
😉 is "white neutralizer". It's the best tool I have found for fixing color balance automatically with one click. For the portrait photographers out there the skin tone tool ("dynamic skin softener") is good too. Just be aware that default settings on a lot of tools are far too high and need to be dialed down. I also find that the "Contrast color range" is useful too as it provides a means of adjusting contrast dynamically so it affects different colors with differing levels of intensity - just move the color slider to observe the effect till you find one you like. Or back out of it if you decide its not for you. Very easy.
There are a couple of others I use now and then but many of the Color Efex tools are too over the top and I never bother with them unless I really want to take the final image away from the bounds of reality. One of the things I really like about Nik products, is this. They are so simple to use and so quick to apply that it encourages you to EXPERIMENT with your images. This produces learning and allows you to develop a unique style that would otherwise be out of reach of most photographers due to the difficulty of doing this stuff using traditional tools like Photoshop alone.
