I'm wondering about the contrast ratio spec of new LCD monitors. It
varies between 1,000 and 3,000 in many cases, but with the screens
all lined up and displaying images in the store I don't see much
difference. Any opinions about how much difference this makes in the
real world, and how you can actually assess the difference?
I wonder if someone who knows about densities and prints might care to
comment on this. I'm too rusty! Is a 1000:1 range the same as a density
range of 3.0? What is the best that prints can achieve? I would have
expected less than 3.0, and if so presumably the blacks are compressed a
little to fit the available dynamic range of the print? I remember
sometimes having to do dodging and burning to produce the "best"
black-and-white print.
I have been disappointed with the LINEAR dynamic range of typical (i.e.
inexpensive) LCD monitors - there is very little display of the lower
blacks so that, if you have an image of 0..255, all levels below 8 may
appear as one black. To get the best visible greyscale reproduction, I
have found that you typically need to decrease the contrast (gain)
setting, and increased the brightness (offset) setting, so that the blacks
are actually shown as dark greys. This then works well with colour
images. Note that I print very little, so matching monitor to printer
isn't an issue for me.
Perhaps these new OLED displays are better?
