5D Mark IV sensor damage tests

[drakegho]

So piggybacking on my last post, definitely photos are coming out washed out and loss of definition and sharpness. Believe there is sensor damage now from the eclipse but have no definitive evidence other than subjective “loss of quality.” What tests can I do to confirm this? Any output tests, etc.? There are zero burnt pixels, but overall the image quality looks very subtly burnt and overexposed

You could try something like a colorite color checker, but without a "before" shot of the same conditions, it is hard to tell.

You could also rent another one and do a side by side comparison - even with the same lens on each!

Assuming that you had the eclipse image in focus, it is unlikely to have caused general damage to the sensor.

Greetings,

Unless you were shooting the eclipse without a filter, it's unlikely the sensor in your camera was damaged.  

I would suggest starting your testing from a clean slate.  Reset your main and custom settings to defaults.  Establish a baseline and progress from there..

The whole point of shooting a total eclipse is to shoot it without a filter during totality!

However, you could wait too long - looking for Bailey's Beads - before you put it back on.
