When cropping a photo is it best to make your adjustments before or after a crop, does it make a difference ?

Thank's
Gary

    Gary,

    I make my final crops after all of the adjustments. Then I save it as a final image (uncropped). That way I can crop it to the desired size now, but can also crop it to a different size later if needed. It will save you somewhere down the road.

    Good luck.

    I've read that it's best to make the crop first, then your other changes. Something to do with the amount of light in the shot, the relative amount of light and dark bits, and how you want to adjust things.

    Crop first, that way, you are setting your black spot and white spot (in levels or curves) with the part of the picture you are actually going to use.

    OK example

    You have an original uncropped picture, but somewhere out of the area of interest (crop) there is a very light spot, and a very dark spot. Looking at a histogram, you look and see the histogram going all the way to black, and all the way to white, technically perfect. You do all your other adjustments as well, contrast, color, the works.

    Now you make your crop, and all of a sudden the histogram doesn't go from one end to the other anymore, or has significantly changed. Part of what you discarded when you cropped previously showed in your histogram, and was part of the 'data' you did all the post processing on.

    As such, I crop first, and then do my adjustments, so I only work with the pixel data that I actually want to keep.

    Hope this helps, otherwise just PM me.

    Gary,

    The amount of difference is going to be shot dependent. Some will have no difference, yet others could have a lot.
