Basically ever since I did Silly Difference Trick and Lum Frequencies. Actually, maybe even before that when I went on that medium frequency ramble. Can't really remember - but it has been on my mind for awhile. If you use Gaussian Blur, you are using a specific frequency. Same with High Pass. With those two, it's easy to divide a photo into two frequencies. Back in my ramble, I showed how to take it a step further and divide a photograph into three frequencies. Now, I have a problem with using set frequencies across an entire photograph. That being that not all frequencies are equal across a photograph. A good example of this is sharpening details around eyes and mouth, but not so much across cheeks and forehead. Of course, a lot of retouchers will mask the different frequencies. We have Gauss and High Pass. The beauty is that one can be turned into the other. We also have Lens Blur, which can do true variable Gauss. If we have true variable Gauss, then we also have true variable High Pass. This means that we can also sharpen in a variable manner in the exact same way that Lens Blur does variable blurring. It's truly a thing of beauty, but it doesn't end there. If we have variable Gauss and variable High Pass, then we also have variable medium frequencies. Did you catch that? [b]Repeat:[/b] We can do variable medium frequencies. You can say, I want this part to be 15-20, this other part to be 5-30, and this part to be 0-10. And we can do so with [i]perfect blending[/i]. We can do so without having to chop it up and mask. Now, going back and forth between Gauss and High Pass also applies to medium frequencies. Once you have the medium frequencies, you can enhance or blast. Rather than say that you want to enhance 5-10, you can say get rid of 5-10. All it takes is a little painting. Well, and Lens Blur. But imagine being able to be a master of frequencies with just a little painting. Loading...
