I recently was asked to shoot a wedding for some friends of mine and while I'm not a wedding photographer I agreed to do it as the groom is a musician friend who I've done live and promo shots for. Also they had a limited budget so couldn't afford the rates for a full time professional wedding shooter so I basically did it at cost as part of my wedding gift to them.
The ceremony shots and most of the group shots are fine but in some of them ( outdoor shots where I used flash for some fill light ) there is a noticeable drop off approximately one third of the frame from the bottom. ( caused by the flash being mounted on the hot shoe and the lens getting in the way )
What is the best way to approach fixing this?
A) Process the shot in Lightroom as normal then use a gradient filter to bring up the exposure on the bottom third?
B) Use the gradient filter then when it evens out the exposure proceed to process the shots as normal?
C) Use Photo shop to create a layer of the under exposed third and try to even it out that way?
The flash drop off is approx 1 to 1.5 stops at a guess so using A) It almost fixes the issue but I can still see a subtle difference on screen.
Is there any other way to fix this issue that I've not covered above?
Thanks in advance for any replies.
EDIT : Turns out to be a sync speed issue rather than flash drop off. The processing issue is still the same though...
