|Some would argue this image is too complex. Too much is going on for some minimalists.|
Recently I joined a Facebook group, Abiotic Minimal Photography. I'd encourage you to join and contribute images but unfortunately the site has been closed. I believe it is now only open for viewing. Being a member, even for a brief time, exposed me to the minimal photography concept. Without knowing it, I've been shooting minimal images for years.
The AMP site had a few rules. One was that images based on flowers or other vegetation were off limits. I expect this was because it is simply too easy to shoot great minimal photos with a flower as the subject.
That said, a colourful wall featuring a colourfully painted window is a pretty obvious subject as well. I see no reason to declare vegetation an unsuitable subject for minimal photography. If it works, for it.
Now, in the spirit of minimalism I am going to keep my writing for this post to a minimum. I'm simply going to supply a good link: 8 Tips to Become Excellent at Minimalist Photography.
If this concept interests you, google 'minimal photography.' There's a lot posted on this movement. Now, get out there and enjoy.
