I like the colours but I'm seeing a lot of noise in the image

well this photo hasn't been cropped and the ISO was 200 as you can see so im not sure i know what you mean by noise ?

possibly the crappy screen on my laptop!

I don't see noise - it may be the texture of the backdrop you used. BTW - do you know the name of that orchid? The color is beautiful. Assume it is a mini phal.Steve W.

sorry mate the wife cant remember the name of it we've had 3 years now flowers non stop

this one is better than white background, but black will suit better IMO. -- love to shoot both airguns and pictures
