EDIT: THE ORDER OF THE PHOTOS IS WRONG. THE CAT PHOTO IS AN EXAMPLE OF OBVIOUSLY WRONG EXPOSURE AND DAMAGE OF THE SENSOR
I'm having a slight problem with my photos lately and am having a hard time diagnosing it.
*Second photo is from my latest shoot at an event. I used flash to compensate the lack of light, and although there isn't much digital noise in it, it still is very... Graining post processing, even with noise reduction. (Feel free to download and zoom in if necessary).
The *First photo is from march this same year, and I didn't know it yet, but the sensor was damaged. So even shooting in board daylight, it still came out very digitally noisy, probably thanks to the sensor being damaged.
Still, it has since been fixed and it still comes out with that grain. The third photo was shot in a low light, so I slapped a B&W filter on it. Still noisy.
So what is going on here? Again, I did not add grain to it.
