Today I got a new camera - it'll be nice to use something other than my phone camera again... after looking at a few models and reading reviews (and finding prices for the shop to beat) I bought a Sony Cybershot DSC-HX100V. It was the model that best met my criteria and reviewed better than comparable models, and has a bunch of features that sound like a lot of fun. Arguably best of all it has a manual focus ring. I've been dreaming of one of those on a non-SLR for some time.
The camera is now fully charged and I've taken some experimental shots. I'm only using the basic auto mode just now, and as it's quite late the lighting was very poor. Yet still I have already got the best photo of one of my fish that I've taken. It's not perfect - his face is out of focus. But the colours are fantastic with absolutely no editing whatsoever. I normally have to at least twitch the gamma, and under artificial light I usually have to play with the colours too.
He's a lovely fish, but evidently being an experimental photo model angers him. But with better lighting and some practice with the features I think that I will get very good results indeed.
