do u like the 'walmart photo center' why & why not?

I like it, you can get some entertaining answers to questions there and just observing the people can be very entertaining. I wouldn't use their services for anything though.

I recently needed some decent prints in a hurry and that is exactly what I got. I downloaded jpgs from the card and an hour later had the prints. Quick & easy - not the world's greatest prints, but hey, it was fast and cheap. Did the job.

I had to get an 8x10 print there once because my home printer broke and I needed it the next day. They had it ready for me and everything, but I thought the print wasn't great (definitely would've been better if I'd been able to print at home), and when I went to pick it up the employee was very rude to me.

Obviously, the rude employee bit just applies to my local Walmart, but it contributed to my overall negative experience. I probably won't get anything printed at Walmart in the future.

can fhotoace please explain the colorchecker in negative film please?

I don't use it but some people are impressed with them. I don't use it for my photos since I use a digital camera I use picasa on my pc. that is way better then walmart.
