A very simple tip I read about today - for use when photographing indoors in a makeshift sorta studio or just any sort of posed photos in your house. Cover any visible electric outlets and switch plates with a piece of paper (especially if the walls are already white or close to white). I know its pretty simple (usually) to clone out something like an outlet. And it wont be perfect - but it will be significantly easier to just clean up the edges of the paper - especially if there is any shadow falling or gradient of lighting across the wall - which would otherwise make a simple clone job cumbersome. Also, depending on how shallow your DOF is - the paper might just render as completely invisible (or otherwise much more natural piece of your background) rather than a glaringly obvious blurry looking outlet. Simple tip - to help get it 'more right' in the camera, to spend less time at the computer.
Just as easy to use the patch tool, make a selection around the outlet and use another area to patch... Then the healing brush to clean it up and clone if necessary... I do it all the time this way....
Yeah like I said - its USUALLY pretty simple to make something that small go away. But if for example you had a shadow falling across it - or the light was falling in a gradient across the wall - it would just become more work to get it right. If you did this tip - you could probably just heal away the edges and be done with it. Most of all though - I think it becomes most useful when shooting in shorter DOF - where the paper will likely disappear, rather than having two little blurry electric outlet eyeballs in the background. It would take all of 5 seconds to do it - and if it saved 30 seconds on the computer (times the number of photos you have to edit) - I'm doing it.
That's when you just hit it again, lol... It works well with textures and not so well with flat surfaces....
