Last Sunday I took some shots of a choral recital. I wanted to shoot RAW because the lighting was tricky (in a church, no flash allowed, half the group in full stain-glass filtered sun, half in the gloomy chancel). I decided to use PEF vs DNG, just so I could squeeze enough photos on the card to avoid changing cards while shooting.
Of course I forgot about the PEF setting and yesterday went out shooting wildflowers using PEF as opposed to DNG for about 350 shots. I may be crazy, but the ISO 400 shots I took yesterday - under pretty gloomy overcast skies and flat light - seem to have more noise in the backgrounds than the DNG shots I've been taking up till now. I haven't done a scientific comparison, but I've looked at a lot of shots taken as DNG's at ISO 400, and these certainly seem different. Not to the point of being unacceptable - but just some cyan-magenta sprinkles. Last Sunday's choir shots were taken at ISO 800, plus I had to do a lot of shadow,highlight, and color temp adjustment while processing the RAW files to compensate for the lighting situation. Those were more noisy than I'm used to, but I figured that was the inevitable result of higher ISO (I almost never go above 400) and the adjustments. Has anyone else switched back and forth between the two formats and seen a difference? - MCC -- - - - - - - - - - - - - - - - - - - - - Mark Cassino Photography Kalamazoo, Michigan www.markcassino.com - - - - - - - - - - - - - - - - - - - - -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
