I was asked to take some beam shots of a commercial LED install while way off the beaten path. I was crushed to discover I left my good SLR at home and only had my Nikon travel zoom (s9100) which does not have a manual mode.
I took some photos anyway with the hopes that I would be able to fix the exposure in photoshop to achieve at least a semblance of comparison.
Has anyone ever done this? All of the photos are f/3.5 but the camera obviously varied the exposure/iso speed as part of its auto mode.
I tried picking one image as the 'base' and used the calculator linked below to figure relative exposure. I entering these values as exposure adjustment values in photoshop does not give acceptable results. They are too strong in both directions.
any ideas?
