What I've learned (focus)

It's darn hard to focus well - I've found that turning on the live view, and then zooming in on the moon works well, but not the best (Auto focus doesn't work). Even looking at RAW pictures, it's not as in focus as I'd like when I zoom in. I guess if I want good pics of the moon I'll attach the camera to one of my ultimate zoom lenses - one of the telescopes. More on that once I try it out.

Any other thoughts from anyone out there?

  1. I will suggest not focusing with live view. I've heard it is bad. Also, for some optical reason I don't understand, I don't think you can always zoom all the way in, focus, then zoom out, and find that the focus is still as sharp as it was. In other words, focus changes as the lens's focal length changes.

    Also, RAWs are never sharp. A RAW is unprocessed, and processing includes sharpening. JPEGs are run thorough a sharpening algorithm. I take my raw shots through some nikon software and then into photoshop (you can go directly to photoshop as it reads RAWs too). The first thing I do in the nikon software is to apply some sharpening (I also adjust for exposure and contrast). I then take it to photoshop where I crop, adjust contrast levels and colors if necessary, and then apply some more sharpening (unsharpen mask). Finally I add some noise reduction.

    You might want to try shooting "RAW + JPEG Fine" at the same time. (it should be some menu option that lets you record both at the same time) and then judging the image initially based on the JPEG. The JPEG fine will serve as a good start of what the RAW can look like, after sharpening etc.

  2. RAW + JPEG sounds good for now. Processing looks like a lot of confusing stuff. I think I need to get my exposures, f-stops, and focus, etc. right before it's worth processing.
