I end up taking about 50-75 exposures every day, and I choose the best from them. The sky looks awfully blue in one of your pictures. Occasionally, I'll tweak the picture a little if I think it needs it. But sometimes, the blue you see is pretty much what the camera saw. I'll retouch them if I think they need it.
Every picture is modified a bit.
I also resize every picture to reduce the graininess of the pictures right out of the camera. In almost all the pictures, what you see is what I saw in the camera. Rarely, though, I will take a picture using the high-res mode of the camera, and then focus on one section of that. Yeah, there was a time when my original Pencam crapped out, and I had a message that said I was out of commission until I could get a new one. The Director of Marketing dropped me an email telling me how impressed he was with this site, and how he wanted to link to it from the Aiptek website.
