Photography?s Digital Possibilities – Retouching
May 18, 2011
‘sponge tool’ is also useful for saturating or de-saturating certain parts of your photo. As with overexposed areas, strong colours draw our attention to them. Use the ‘sponge’ to attract more attention to the important parts of your photo and away from the distracting things in the background. And as with all digital alterations, use it moderately, not more than what is just needed. Less is more.
But perhaps the neatest trick of all is this one:
Chromatic aberration effects and chromatic noise resulting from high ISO setting on the camera can be a pain to deal with. Noise can be removed with special plug-in filters such as NoiseNinja (new Photoshop models have noise removal build in and it is getting more and more common), but they leave everything a little less sharp. Another option is to tediously retouch away at miniscule details all day long. But there is a little combination that works just short of magically when it comes to chromatic disturbances, try it out: First go to ‘Filter > Blur > Gaussian blur’ and set the radius to approximately 7 px. This will of course make your image completely blurred. But then go to ‘Edit > Fade Gaussian Blur’ and select ‘Mode = Colour’. You’re not going to believe what happens until you try it yourself. The sharpness is restored and all chromatic disturbances have disappeared! It tend to leave your image with a little less colour saturation, but this is easily taken care of in ‘Image > Adjustment > Hue/Saturation’. You might also want to check for other artefacts. If you find any, they are now easily removed with the ‘clone stamp’ and healing brush’ tools described above.
