I try not to do my photos indoors, Sometimes I can get away with it if it's daytime, but after hours my shots all look orange. If I use the flash it's just way too bright, I have been known to use a post it note to cover half the flash...this sometimes gets results. Most of the shots in my gallery are done outside, you dont need full sun, infact an overcast will work, just watch out for where your shadows are in bright sun.
I dont use a tripod, the speeds that the camera runs at in daylight it is not required. You
can get away without one , place the camera on a table top or some books for height. Digital photography doesn't all have to be about depth of field and F stops, let the camera do all that, set it on auto and shoot away.
Use the zoom function but dont go in too far, 2 or 3 times magnification is fine, if you can find a picture of a flower on your camera then press it and try some shots in the macro mode. Dont forget, you can move, the minis cannot, so try moving back or closer to get a result.
Your camera only eats batteries, not expensive film. I always take at least four shots of the one mini, after that it's back inside and unload the camera's memory...then I use PIX resiser, it's a free download (google is your freind) that will let you take a 1.5 megapixel shot down to a 90k picture ready for posting with the click of a mouse, you can use something as basic as MS Paint to do your cropping. From what I have seen with Photoshop you can get away with murder, I dont use it..what you see is what you get with my pictures.
The best advise I can give you (at this price) is take
lots of shots, go set up a few minis and go for it.
P.S. visit my gallery, it's the only way that you'll get better
