Originally posted by redcurl I just installed this firmware coming from v1.0,
question: why are fine sharpness and fine sharpness 2 cursors "moved" simultanously..? shouldn't the fine sharpness and fine sharpness 2 controls be independent of each other ?
Haven't found a technical explanation what both controls modify.
I thank you in advance for kind reply.
The Sharpness slider adjusts the contrast at the edge of highlights in the image. It's particularly noticeable on pictures with a lot of detail, like a close-up of tree bark or a coarse material. The higher the "Sharpness" slider, the more each strand of material stands out, but then the highlights can sometimes get exaggerated over the shadows, which may or may not look very good. I believe this is a post-processing option that affects JPEG output, not RAW. Although I think the RAW file keeps the sharpness setting stored in the EXIF data for when you convert it to other formats.
By default, this slider will affect a specific number of pixels on both the dark side and the highlight side of the separation. Fine sharpness reduces the number of pixels that this setting affects, so that the sharpening looks "finer" and less blatant. Fine Sharpness 2 reduces the number of pixels being affected even more than Fine Sharpness.
Here's a crude example:
The following are 100% crops of pictures I took of a lens cloth on my desk. The camera was set to Manual, with shutter speed at 1/50, aperture at 7.1, iso at 400 and flash at -2 ev using my 18-55 WR kit lens at 18mm from about a foot away. "Custom Image" was set to "Bright". All other post-processing is turned off, including noise reduction. JPEG quality is set to max.
This one was taken with the sharpness slider at -4 and with Fine Sharpness disabled:
It looks kinda blurry, especially considering this was taken from a foot away.
This one was taken with the sharpness slider at +4 with Fine Sharpness disabled:
It's much sharper, but the highlights are excessive. The cloth looks like it has more grain than it should. Also, the sharpness processing has highlighted the noise as much as the grain, so the noise is a lot more visible than it was in the first picture.
This one was taken with the sharpness slider at +4 with Fine Sharpness enabled:
Here the highlights appear to have been blurred out to allow more of the blue to show through. In the middle of the picture, the cloth shows less noise. However on the speaker cone behind the cloth, the noise is even worse than the last 2 pictures.
This one was taken with the sharpness slider at +4 with Fine Sharpness 2 enabled:
The highlights are sharp, but still allowing the blue to show through properly. There's a lot of detail to the grain here. There's some noise on the cloth in the middle of the picture, but only where there were more visible highlights to begin with. However the noise on the speaker cone is worse than ever, and now it looks more washed-out because of all the random highlights that got "sharpened".
