Not posting this as a chosen picture, just posting this one because I've encountered this light issue before with curved fruit ... where the left side has a differently colored portion, almost like it's out of focus. And I'm not sure how to solve the problem. Actually, I did make it go away by putting the light head-on rather than from the side. But then I got even more glare than this and lost pretty much all the skin texture.
I think this might have to do with what I was reading today, but I didn't totally understand what I was reading today. Dealing with direct and diffuse reflections and family of angles for the lights and camera.
Now you know I am as much an amateur as anyone but I would try with something gauzy over the light to reduce the brightness. This is what I do I experiment with ideas. Then I say @vignouse can you help. Since he follows you he will probably show up.
@joansmor@francoise To my eye at least this is over-exposed, which is not helping, but the problem here is light reflected from the background which is adding to the direct light and over-exposing the rim of the fruit. To solve this, you need to move the subject away from the background and/or use a black flag (the opposite of a reflector) to kill the reflected light. Hope this helps...
@vignouse Ah that makes perfect sense. I use black backgrounds mostly so hadn't experienced this yet. I just made a copy of this picture, @francoise explanation and Richard's insight to word and saved in a folder called Lightamateur so this old lady can find when I need it.
