Quote:For how long have you been without your first printer for the monitor to drift that much? Do you notice any difference to how your images look now on other computers now?


A gap of around 3 months between serious print jobs

Fine on other computers

Dave, thanks for your helpful input on the difference between DLP and LCos projectors. The one we have is a 7 year old, then top of the range Canon projector. that tip about running in Quiet Mode is one I will pass on the "Projector Person"

Brian, the "Quiet" mode is appropriate to Cannon XEED LCos projectors and may not be relevant for other models.

Thanks Dave, its an XEED we have, from memory its the 600 (hellishly expensive but we were lucky enough to get it via a large lottery grant along with a lot of other kit)

Anyway, I've passed your info on so maybe it will help, thanks again

Too many good points to use "quote Comment" button - but thanks lads, a mine of information, which I will return to again and again. Too much to take in at a glance, but I know the right info is in there - thanks again!

It was indeed a B+W image, a portrait of an old man. I loved it in camera, on the monitor and in the A4 print. The blacks were black and his white hair shone and the contrast and detail were really good. Most of his face was in deep shadow and the judges comment was "what a strong image..." But it was only half the image in PDI that I had on my monitor and in print! It was much brighter, showing area's which were in deep black elsewhere as a sort of darkish grey!
I will mention it at the club.

Thanks again! Grin

A thing I am still struggling to come to terms with is that processing an image for DPI is totally different from processing for print.

I tend to specialise in print making (mainly for sale) so don't really need to think about that but I made the mistake some time back of putting up a print file for PDI (correctly sized) and the result was diabolically bad

I'm sure there must be some DPI specialists here who can guide us on the best way to produce DPI tailored files - I know I need help! Tongue

There must be some way to calibrate the projector for contrast and brightness, even if it is just by eye.

As I said Paul, we have tried to do it, we got in a professional to give us a talk on how to do it, including recalibrating it and none of the clubs in the region have cracked it - I'm just hoping that Dave has the answer Smile

Its been quite a while since I set one up, the room needs to be dark as in cinema dark, and I would always leave the equipment on for 30 minutes or more to warm up before I started fiddling.

I don`t believe this bit is all that important Brian even 72 DPI will do and in 8 bit and srgb.

sorry Paul, finger problem, that should have been PDI file Blush as in Projected Digital Image (I know that the DPI is something entirely else, our club system works with 96ppi and 1440 x 1050 pixs files )
