cindy,
digital camera noise removal is
psp's noise remover. i'm sure
ps has one. you can also try Neat Image, which a lot of folks here use and recommend.
clarify, i'm not sure what that translates into in
ps. flora would probably tell you to use the shadows/midtones/highlights filter or adjustment layer.
psp has that as well but clarify kind of does that all in one step with a single slider. it heightens the highs and sharpens the lows. so, it seems to be sort of a cross between brightness/contrast and shadows/midtones/highlights...sort of.
and push, i'm told, is sort of like a very heavy smudge in
ps. smudge tends to smudge as you push it around, but the effect only carries the paint a short distance. push carries it continuously, especially at higher opacities.
one good way to get rid of clone marks is with a light 'push' or 'smudge'. just dont overdo it or you'll have more marks to deal with.
and for the doubling of image size, that's exactly what i do, i double the actual size of the image, not just a zoom. so, if an image is 400 x 400 pixels, i make it 800 x 800. sometimes, with really small pictures, i'll go even more. (actually, i'm doubling all the sides, which quadruples the number of pixels in the image. this is what reduces the aliasing)
restorations are normally quite different from other photo manipulations/alterations. they generally require more hand work and fewer filters. most of my hand work is done with clone, push, and airbrush all done on blank raster layers with 'use all layers' set on. and just recently i watched a video that was posted by a new user here on
RP and learned a new technique for cloning, selecting the area to be cloned and the area you're cloning from and doing it all within the selection. so, i may give that a try also.
