I bought my D3500 just six weeks ago, so am still learning. I'm sure I've just scratched the surface of what I should know.
My previous camera was a Fuji S7000. Prior to that I had a Nikkormat, bought in 1970.
The problem I am having currently is irritating rather than limiting. There are two images stuck on the camera's memory card. I'm unable to delete them. When I try to delete them the camera gives me a message, "Cannot delete. Protected image". I normally delete images from the camera after I download them to my computer. I have downloaded these two images, but am unable to delete them.
I'd be grateful if some one could instruct me on the process.
