    Question Brightness and Contrast of digital photos ?

    Does anyone knows how does the auto-level and auto contrast of the adobe photoshop works? Does it auto adjust the brightess and contrast of the photos according to your monitor settings ?
    Sometimes when I did a auto level and auto contrast of the photos, the pictures look fine on my lcd monitor but looks much darker at my office crt monitor. Is it better to calibrate a CRT monitor and use it for digital image editing than a lcd monitor ?

    Btw, does this photo looks too dark to you ? Can you clearly see the motorbike at the background ? Thanks.

    Hi Majere2sg.
    Your pix is ok to me. But then again, my monitor (CRT) is already setup for offset and photo-lab printing. So.....
    Normally, I'd say that you'll want a 2.2 Gamma for PC/Windows-based systems. And decide what you want out of your shots - like for print (WYSIWYG 95%) or for Web only, or what?
    Anyway, you mind PM me how you setup your monitor? Like what brand/model, the gamma settings, etc. I'll reply with some tips and where to go to get your gear set up....

    Cheers,

    the pic seems ok to me

    I believe the auto level and contrast work based on the histogram of the pic, not the brightness of yr monitor. A CRT or LCD monitor will be equally good for digital imaging as long as it's calibrated.

    If u r not able to get hold of calibrating equipment, u can try this

    1) Develop a few pics and tell the lab ppl strictly no correction.
    2) Adjust the brightness/contrast/colour according to the developed "raw" pictures.

    I have been doing this and been patronising the same lab .. so this work pretty fine for me.
