"Rain was here"

It rained almost the whole night, and as soon as it was over I thought it's a perfect time to go out and experiment some more. These pictures are FAR from pro quality (like Tom's, for example) but I enjoyed taking them so much and I think I'm making a tiny progress :)

First, my pitiful attempt to capture sun's rays through the branches ;)


The next photo is somewhat a mystery to me. The flash was on, but the lighting turned out somewhat weird on the image. The middle is super bright, but everywhere else the colors are dark. No clue what happened there... But I kind of like how it looks.



A little closer...





I was a little obsessed with droplets today...





It was fun. I have at least 25 more shots, but they are basically the same thing from different angles. Experimenting :) Anyways, I came across a problem when I was saving these images. I read that JPEG format is bad because the photos end up with worse quality. That's, however, the only format I've used so far. How should I save them then?
