Thought I'd start a thread on photography advice -- hopefully, many others will add theirs!
In no particular order:
1) Shoot using RAW (or RAW + jpg) format. You may not care about RAW now. You may never care. But if a time comes when you do care, you'll regret not having RAW files from your past photos to work with.
2) Unwanted motion blur is almost always more destructive than noise. Use an exposure time that is short enough to mitigate motion blur in your photos (unless, of course, motion blur is desirable or doesn't matter). Yes, this can make the photo more noisy, but you can mitigate noise with noise filtering software, whereas [undesirable] motion blur is typically a much bigger problem.
3) Achieve accurate focus. This might seem like a "duh" comment, but depending on how badly the focus is missed, it can absolutely ruin a photo.
4) Learn to process/edit photos with software. Don't let the camera and/or default settings of a RAW converter constrain you. Neither the OOC (out-of-the-camera) jpg nor the default RAW conversion settings are the "authority" as to what a "real photo" is or isn't. There's no pride in saying "straight-out-of-the-camera" as if that photo is somehow more of a photo than one that has been processed by you with skill and care. Of course, if, say, you're an event photographer and don't have time to individually process hundreds of photo, then, for sure, the camera's jpg engine and/or RAW converter defaults matter. Still, my advice is learn to processing/editing if even for those few special photos that "deserve" it.
5) Don't use this attachment for taking event photos:
Unless in Texas, Florida, or Tennessee -- should be fine, there. : )
