I have just started shooting in+ Jpg and I am new to processing. I noticed that when I convert my files to jpg that the picture size is smaller when compared to the original jpg file in Photoshop. The orignial jpg files are around 121 x 180 cms long (72dpi) compared to the same image that is the converted to jpg file which are about 32 x 44cms (350 dpi). When I tried to order a canvas print from the jpg ( converted) file, the files where not high enough resolution for a 12x18" canvas even though I have the image quality set at the highest setting. I read somewhere that when you increase the dpi that the image gets smaller. What dpi should I have my conversion program set to?
I am using Digital Photo Professional to convert my files to jpg and Photoshop Elements for touch ups etc. The default dpi on the program is set at 350 dpi.
Any other processing tips would also be appreciated, thank you.
