Title: Hot Pixels ??.. H2/P25 pictures... Sunrise/Archit.
Post by: phildog33 on March 02, 2007, 04:30:19 am

I was shooting Columbus Circle area during sunrise with the H2/P25 and all shots were around 40-50 seconds exposed. All came out fine, but one file had 100s and 100s of hot pixels everywhere.

Check the second file attached

Any advice?
