I could do with some advice please, all of the images I have taken this week with my Canon 750D have had a great deal of white dots on them which are easily seen & this happens with both jpeg & raw images. When I zoom in on the images on my laptop they look like white pixels, I took a couple of shots with the lens cap on & I can't see them but it happens if I use my kit lens or my Tamron SP 70-300mm lens with shutter speeds of 1/10 - 1/800th of a second (haven't tried going either side of the shutter speeds) & ISO has no baring on the white dots. Could I be suffering from a lot of dead or stuck pixels ? I know I do suffer from some hot pixels on long exposures which show up as either red or blue
