Hello, Brian!
I recently took 100 headshots and have found, I think, a dead pixel smack in the middle of my frame (or at least pretty close to the middle). Looking back to even photos in December, I see it in those images also. For the recent headshots I did, the pixel falls on almost all of the photos between nose and chin so it was pretty hard to miss.
I've done some reading about dead, stuck and hot pixels, and I think this would be dead?
I can edit out the dot, that's easy (and tedious 100+ times). What I haven't found much information on is what to do about the camera. It's a 5D Mark iii and 10 years old. I can send it to Canon for repair, and maybe the choices are mapping it so data is used from surrounding pixels? Or sensor replacement? I think the cost of the mapping repair is less than $200, the sensor replacement I have no idea.
I wasn't in the market for a new camera, but I do wonder how much is too much to repair this camera.
Is indeed what I am seeing (on the chin in the attached crop) a dead pixel? Brian or others, have you dealt with this and have thoughts or advice?
Thank you!
