tonylong ...winded  More info | Apr 10, 2011 22:00 | #2 I'm not sure where on the image the smudge you're referring to is but are you using a UV filter? If so I'd not use it except in severe conditions because they can cause bad flare problems. If you're not using one, well, where is the smudge, unless you are talking about the purple area that seems to be part of the flare in some way... Tony

I stand to be correct though. Like tony asked, did you use a filter? It might just be the lens and how you were angled. Many things can cause this to happen. ShotsInTime

Those will change size and shape until they eventually go a way as you open up the aperture. You can see the same thing in this night shot Mark-B

Apr 11, 2011 00:29 | #5 I think he's talking about all the mess around the sunflare. OP I too was led to believe that the front element had virtually no effect on the final picture. However, I learned that does NOT apply when shooting into the sun. I shot some sunset pictures in Hawaii and there was some dust+sand on the ND filter. Well, I got all sorts of little dust flares only noticeable in dark areas of the image. Please visit my Flickr

Apr 11, 2011 00:36 | #6 Sorry for not clarifying but yes I'm talking about all those little hexagon shaped bokeh around the sun. I know they are caused by the finger smudge on the 18-55mm lens because after I wiped it clean the rest of the shots didn't have those hexagon shaped bokeh around the sun. No filters were used. So whats the best way to remove them in photoshop?

You can minimize them in the future by staying under f/9. Mark-B

Did you reduce the aperture or move the sun to a less prominent place in the frame after wiping away the smudges? Mark-B

I checked the aperture info as I go through the photos and when I reduced the fstop from f/22 to f/20, the finger smudge/bokeh did become less obvious. It's still noticeable though.

Never thought about shooting into the sun attributing to the cause - I knew about the tiny f-stop causing flares, and the front element not making a difference. Hmmm, guess I better keep that lens pen handy.

The spots should move if it were flare ,no?  HOSTED PHOTO please log in to view hosted photos in full size.  HOSTED PHOTO please log in to view hosted photos in full size.
