Description
A detail of field bindweed (Convolvulus arvensis , divlji slak in Croatian) flower. It's a quite small flower, 1-2 cm in diameter.I'm not very satisfied with quality of the photo

Is this halo-like affect at the flower edges caused by poor lighting, or is it an issue with the digital camera? Something else?

It's a limitation of lenses, that is specially visible where are high-contrast transitions, see [link]

So reducing the appature(sp.) diameter and compensating for that with a longer exposure time should minimise this affect???
(after reading the linked artical)

Likely, because it's depending on the lens, and if you decrease aperture you use a smaller lens area. If you take a look at EXIF data for the pic, you see the exposure is 1/320 s. I could go to manual settings, and go to 1/125 or like. But it's hard to see small aberrations on the built-in LCD, so I was under a false impression the photo was OK.

Could you now assume that in high contrast the cameras' computer is a little off and take the shutter speed down proactively in each situation like this?
Or is is a shot by shot thingy?
(Only picking your brain so I can try it with my camera, not telling you what you should do....I am learning heaps this way :-D )

Yeah, I could, but then I'll have to switch from automatic to manual.
I'll try

Ahhhhhh...yes, I haven't poked at my manual settings either. Thanks for working me thru the hypotheticals of how to do that though
Now I know....

No problem, you're welcome. Playing around with settings won't harm your camera and can be a lot of fun

Zoom in and you'll see some color on the flower edge where it should not be. Also, note a lot of noise
