Help (macro problem)

[james_dunbar]

<p>Hey not sure what forum to post this question on so I though I would just try this one. Below is a picture I took of a house fly with a 24mm sigma prime lens reverse mounted. Now I'm not too sure if its flare or over exposure or what but does anyone have any ideas on how I can prevent that ghosting effect in the middle of the picture? Furthermore to make matters a bit more difficult the effect does not show up on the cameras screen, so I walk away thinking I've taken a really good shot and its not until I get on a computer that I see its all white.</p><div></div>

<p>yes, overexposed</p>

[tonmestrom]

<p>just a simple correction</p>

<p>It looks like hot spot. May or may not be correctable at this magnification. How did you reverse the 24mm sigma?</p>
