I have been trying to take some product light box shots never experienced any issues prior to this but since yesterday I want to pull my hair out.
Ok so the problem is that when my flash faces the ceiling and i'm taking normal photos around the house it is functioning absolutely perfect but when I hold the camera in the light box and the flash faces inside the top of the light box, I take a picture and I notice the red light turn to green all the flash setting disappear and it just says ETTL in the top corner and the image is so over-exposed that you can't even see the product, just pure white.
Why is it that outside of the light box the flash is functioning fine and inside it gives out massive bursts of flash? What am I doing wrong?
I have changed the batteries numerous times to fully charged ones, the batteries I am using are duracell rechargable ones which are pretty good but then i've also tried my cheapo Active energy batteries and I have the same problem, mega bursts in the light box and normal shots with good flash outside the lightbox.
Please don't tell me my flash is damaged.
