Is 4M image size the same as 4MB?
Thanks so much for the answer to what is probably a very basic question! I am working on resizing photos of my artwork for show entry. I am not a photographer!
There is Mega Pixels (MP) and Mega Bytes (MB). Two totally different things.
MP (Mega Pixels) is the number of individual photocells, Light capturing devices, on a sensor.
MB (Mega Bytes) is the amount of space taken up for that file to store it on a hard drive/SSD/USB stick/whatever.
