Hi. I was taking photos of the lunar eclipse last saturday and as I downloaded them to my PC I noticed that the JPEGs looked just fine (as they were on my view finder) but the RAW images were just far too grainy.
These were the settings I used:
ISO 400
f/5.6
exposure 1/2000
Can anyone please explain what's hapenning here or provide some tips to avoid them next time?
Could be the compression, RAW contains quite a bit more data, perhaps the loss of detail that comes with the compression used in JPEGS cut the noise out. Or perhaps your camera has two separate settings for JPEG and RAW resolutions?
I'm sure I did read somewhere that generally in SLRs there is some automatic "post-processing" that goes into the JPG version while the RAWs (as you'd hope) are left untouched. Any RAW editor should be able to smooth them out.
These guys are both correct - your camera processes jpegs, whereas the RAW photos are exactly that - raw. They're truer to the actual capture, and need to be edited as such.
Tweets ahoy!
