How often at photographic club meetings do we hear the comment “It doesn’t look like that on my monitor” when an image is projected? Obviously the fault could be with the projection system (i.e. computer and projector) or with the monitor, or both!
If you are serious about producing good quality images for projection or printing, you could start by checking your monitor. I have just published a completely revised technical note including two test cards which will show at a glance whether your system needs adjustment.
Please have a look at this and let me have comments.
