Why do the flowers have halo's?

So after a bout of scattered showers today I went out looking for some wildflowers with water droplets formed just on their petals. I am shooting with a canon eos 20d and most of the time shooting today I was using a 100-300mm lense to get "macro" shots of said flowers. Anyways later when I uploaded them into lightroom before I had done anything to them I noticed that many of the pictures of the yellow colored flowers have a slight halo of light and fuzzynes around them its not like their out of focus just.. odd.. I was shooting at Iso 100 with a tripod.


-thanks


P.s. if you need more info i will try to supply it

Why do the flowers have halo's?
Did u use a lens filter on the camera? The 'halo' could simply be caused by water droplet glares. Nice effect though.
Reply:i agree with einstein 07: happy accident with a great effect.


the result of humidity i'm sure, and not using a filter as has been suggested also.
Reply:You probably had some water vapor condense on your lens ever so slightly to create a halo effect. After a rain (and subsequent sunshine) there lots of water evaporating and that can easily condense on to your lens. This can happen the easiest when come IN from the cold outside to warm humid area. But it can happen any where there's humidity (like over damp ground under hot sun).





Just imagine cool shiny object (spoon, glasses, etc.) over warm coffee or tea cup. There barely a visible vapor but still enough to condense on the shiny object (and just as quickly dry away).

Here's a little factoid that might help with your hobby. You don't have to wait till a shower. Many pro photographer carry water spray bottle to create that wet / rained flower effect. Many nature photographer carry spray bottles to spray down butterflies to keep them from flying away. Butterflies get wet with morning dew. They sun themselves in the morning light waiting to dry. But a photographer can prolong that by spraying it down with fine mist.





And if you liked the halo effect, then you can also get a fog filter so you don't have to leave it to chance.





In fact many of the NATURE (PBS) scenes are actually shot in studio (staged).





Hope my little factoid helps.

Reply:use a poloraid and/or a UV filter.
Reply:It is likely that the flowers were back lit. Meaning that the sunlight was coming from behind the flowers. This will cause a halo of light around the subject, which can make for very interesting portraits and nature scenes. Back lighting can also make beautiful silhouettes at sunset, like black trees against a vibrant orange sky. Be creative with this, it is not a flaw unless you don't want it in the shot.





To avoid back lighting, simply change your position. Move around to the other side of the flower for front lighting (were the sun is now behind you and shining on the front of your subject). Or move to were the sun is at your shoulder for side lighting. Each of these positions will create different effects with shadows, halos, etc. These different positions may also require a different exposure, so adjust accordingly.





Happy shooting! p.s. I use the Canon 30d, it is very similar to yours. Great camera!
