Here's what I tried.
  1. I took a 2048x1366 crop from the center of a photo with a lot of detail.
  2. I reduced the crop to 512x342.
  3. I enlarged the 512x342 image,
    • Once straight to 2048x1366, and
    • Once to 1024x684, and from there to 2048x1366.
  4. Then I compared the three 2048x1366 images.
While neither of the reduced/enlarged images was anywhere close to as sharp as the crop I created in step 1, the enlarged image I created in 2 steps looked like it contained more detail than the enlarged image I created in 1 step.

The next time you resize your images for submission, you might want to do it in a couple of smaller steps, instead of one big step.

Using free programs is good for starters, including the "Gimp". But you must have figured out why they are free by now, all of them lack the refinement a program like PhotoShop has.

I understand PhotoShop is an expensive program, but Elements is also a premium editor, well within the reach of any "poor boy" like me. So do yourself a favor, go a step beyond the freebies, your images will love you for it; believe me.
