I'm sure these aren't your FIRST photos. The first could use a bit more light. Also, the small leaves on the bud are in focus, but not the flower. I really like the colors. Crop the second one and print it! I think you've found a good spot to help hone your natural talent.......I have!:thumbup:
Petunias? Lovely colour and I know difficult to resist with a camera. Unless you are aiming for a special effect try and focus in on the stamen. This last few days the wind has made it impossible to take any flowers and ideally the tripod should be used although I admit I only do when I am trying for a competition print and not for "pleasure" If you have Photoshop or the like - be prepared to "cheat" or post process is the polite term - I had a quick go below - no alteration of colour just blur of background and desaturation
Go and have fun - but beware - it becomes addictive, but we look forward to your results.
