It is not an operating prison

Bring a tripod, it is fairly dark inside. Get there early as it can get pretty busy.

Yes, it becomes more noticeable at print size. To see what is happening check the file size before and after the JPEG edit. That is the information you are losing. With the file size you can get an idea how large a print you can make. It is okay to print an 8x12 from a file of a few megabites but when it goes down to 500KB you might have a problem.

Very nice. I like the bottom one. Gives the mountains more room to breath and I like having more of the setting.
