File:Bilder im Hofgarten, München, Deutschland4.jpg[edit]

Hi Derek, I didn't really understand this comment of yours:

This could use an unsharp mask (10%, radius 35 pixels) for localized contrast enhancements beyond simple curves, but it's good enough for me now as is.

with regards to the picture in the header. Do you mean denoising mask? If so, there is no way to set a radius for that in LR (but for sharpening). Do you use a different SW?. My intention was actually to try it out, but I am not sure how. With your comment, are you suggesting that the sharpening would look better appliying at the same time a denoising beacause this one picture is noisy or independently of the noise a picture could have?

@Poco a poco: The concept is en:Unsharp_masking#Local_contrast_enhancement. I use photoshop CS2, an old version, but the concept is the same on all versions of photoshop. I've never used LR, but I found this article. When you do a normal details sharpen, you use a small radius and a large amount. When you do localized contrast, you use a large radius (I usually do 35 pixels) and a small amount (I usually do 10%, but as much as 15%-20% for certain kinds of images). I always leave the "Masking"/"Threshold" set to 0. "Detail" in LR is new, but presumably you can adjust that to whatever looks best. Be careful, if you do too high an "Amount", it starts to posterize and halo.
Rather than sharpening per se, this adds selective (local) contrast without the heavy luminance and saturation changes caused by a curves adjustment. Unsharp mask is also available for free in en:GIMP.
Compare before and after.
I think I'll write up a how-to guide for basic photo editing. -- Ram-Man 18:53, 19 December 2014 (UTC)

You really mean it?[edit]

Must have been an edit conflict. I thought I correct that. No I did not intend that. Did you revert it? -- Ram-Man 14:29, 17 February 2015 (UTC)

Sorry about that. -- Ram-Man 15:44, 17 February 2015 (UTC)
