Re: [photoshop-beginners] Insight on calibration

Monitors should be calibrated at least once a month. They do drift in their brightness and color balance.

I think you could bring your monitor to someone who has a calibration package, but to me that seems an awful lot of hassle. There would be the temptation to "get away with" calibrating less often than needed. Then, at some later time, you'd find out that you need to re-edit all your images in order to get them to print the way you want them. Not recommended.

There's a very old-fashioned way to "calibrate" a monitor by eyeballing brightness, colors, etc. It used to be included in earlier versions of Windows, but I think it's been discontinued in recent years. It's almost impossible to accurately calibrate for color balance by "eyeballing" (guesswork), and most of us will end up with a monitor which is too bright for accurate printing.

Again, if you're not going to print your images, or have someone else print them, it may not matter much. Guesswork might be good enough - but of course there could be big inconsistencies between monitor, cell phone, tablet, prints, etc. Here's one of many good articles, from a very quick Google search:   http://www.tomshardware.com/reviews/spyder4-monitor-calibration-image-quality,3581.html

This thread goes along with questions I've been wanting to ask about calibration:

1.  How often does a monitor need to be calibrated?  

2.  It seems wasteful to spend over $100 for a Spyder calibrator just to use it once, or once a year.  Can I bring my monitor to somebody else who has a Spyder and have him calibrate it?  (Obviously I can't borrow a Spyder and install it on my computer, as that would violate a license.)

3.  I use a computer running Windows 7 Home Premium.  In the Control Panel's Display section, there is a way to calibrate a monitor by adjusting settings until sample images look correct.  How good is that feature?  

Thank you very much!

Thanks all! I guess you might consider my goal to have my images to be consistent (or as much as possible) across all my devices from my large processed TIFF files to my smaller JPEG files on my iPhone and also when posting to my website. 

I'll need to see what my default color space is and go from there. I have heard of spyderpro but really haven't had this problem before the new computer and PS. 

Thanks everyone for your help. Additional insight is always appreciated. When I get back to my computer tonight, I should know more about what color space I'm starting with

ColorMunki may set the color space, but not all monitor calibration packages do that. Spyder3Pro and Psyder4Pro, for example, do not set color space.

Adobe RGB is not for "low resolution". It's a *wider* gamut than sRGB - displays more colors. That won't show up on a monitor, because the color gamut of monitors is narrower than that of prints. For non-critical viewers, the difference between a print made with sRGB and one made with Adobe RGB might not be noticeable. However, if you're interested in the best print results, shooting and printing with Adobe RGB will give you smoother gradation of colors, and more accurate colors. For some images, the difference quite dramatic in the final print.

it's more complicated that i let on, and i certainly haven't tamed it. but here goes. one needs to use hardware like ColorMunki Photo (that's the correct spelling). and that will set your color space. Most people use Adobe (1998) RGB. Adobe sRGB is supposed to be for computers screens and low resolution. it just gets more complicated from here.

That sounds like what happens if you use the Adobe sRGB color space.  I forget what the name is of the color space that most browsers use, but I usually keep PS on that color space.  I don't know enough about the reason to use Adobe sRGB to use it intelligently.

Good luck!

Friends - 

I recently upgraded to PS CC and a new IMac 27 that I'm using to process images. I take all my images in RAW, process with my choice plug ins and they look fantastic on my screen!!! Yay! Then, I downsize and convert to jpeg and send to my phone or Facebook. YUK! They desaturated and sort of washed out. 

Does anyone have any insight as to how I can get my images to look good on my phone like they do in full resolution?
