Colombia and a technical question

[goosekirk]

Colombia! Land of drug cartels, civil war and kidnappings galore, or so "they" told me before I came here. The reality is not quite what I was led to believe. You can check out my ever-changing Colombia gallery and maybe get an idea for yourself:

But I also have a technical question. On the first page of this gallery, the top four photos were taken with a Fuji 610, and the bottom eight with a Fuji 601. On the second page, it's the bottom four that are from the 610.

Lately, I've been processing my photos differently. I use ACDSee to crop, apply a little unsharp mask, and adjust the levels. Then, for posting to PBase, I resize and sharpen once with Irfanview. I'm not sure if I like the results or not. Please take a look at the top four on page 1 and bottom four on page 2... are they overprocessed or no? Any suggestions for how to improve them?
