Somehow, the high pass filter does not seem to work using the marco recorder. I use very often the liniar light + 0,3 high pass filter on my picture, however I do not see that it is applied when I start it from the library. Denoise and other settings are running fine.
I'm working on sharpening as it's a new concept for me, but ultimately necessary when editing RAW files. I don't think I've necessarily got this right, especially with dark colours. For reference, these have been taken with an iPhone 6s in natural light, are all PNGs at 1600px in width, output with an sRGB colour profile, with Bicubic sampling (apart from one image). For example, take the first image (1). It's without noise reduction, a clarity filter, or an unsharp mask. Notice the heavy noise (both colour and luminance) on the black t-shirt. The second (2) is with a denoise and clarity filter. The t-shirt here is too smooth, with zero noise on zoom at the heavy expense of detail. However, the third (3) image (which adds the unsharp mask) is perfect when viewed at a small size, but you can see a ton of noise when you zoom in. I'm thinking my sharpening technique is off here, but I could use some advice on whether this is acceptable. How can I retain the detail in the blacks, while not introducing noise when zooming in? I've tried setting the threshold, but I still get the problem of an undetailed flat t-shirt. I've also tried a High Pass filter first, which improves the initial sharpening, but as soon as the Unsharp Mask and Clarity filter are brought in, the noise returns. In short, I can't remove the noise and bring out the detail in the darkest elements without introducing noise and I'm getting annoyed. :-) Any advice, or am I simply overthinking it all and have got it right?
Hi, I noticed that when you use the High Pass Filter in AF there is an option for clicking on "monochrome". Is that used to desaturate the image before applying the HPF. In Photoshop, as far as I know, you have to use a Hue Saturation Adjustment to desaturate the image before applying the HPF. So, am I understanding correctly that by clicking on "monochrome" with the HPF I don't need to desaturate the image separately? Thanks!
