"Working" Color Space - sRGB, Abobe RGB, and ProPhoto RGB

Look what happened to me:

HTTP response: 404 | MIME changed to 'image/gif' | Byte size: ZERO | PHOTOBUCKET ERROR IMAGE

HTTP response: 404 | MIME changed to 'image/gif' | Byte size: ZERO | PHOTOBUCKET ERROR IMAGE

WOW!! I had no idea. If that's the case then those files will be even larger.

For some high end product shoot where technically perfect color rendering needs to be 100% right on, that would be a candidate. My brides though are very pleased with my plain old sRGB.

What I got out of my research on ProPhoto RGB is that it really needs to be used in a 32 bit environment to avoid certain problems associated with spreading the gamut too thinly over 16bit.

Erica - so I'm guessing the muddy looking first shot was aRGB and the second one is sRGB?

The first shows an "Uncalibrated" color space and the second is sRGB.

Well, at least I was half right Mike .

For only $5,000 USD you can get an NEC Diamondtron 22" CRT, which handles more than 97% of aRGB.

Of course, if that's not good enough, there's always the Eizo Coloredge 22" LCD that does 100% of aRGB, and will only set you back $6,000 USD.

SOLD!

"Uncalibrated" was the Exif term used until a couple years ago for anything other than sRGB, so it could very well be AdobeRGB.

Well, Jeffreys EXIF viewer reports on the first one:
"Embedded color profile: “ProPhoto/ROMM"

On a side note: AFAIK, ProPhotoRGB is used in 16bpc. Only 32bpc I know of is when doing an HDR merge.

emurph2,

Your photos are the exact reason I started this thread. When I was doing some print for work a custom who had some portraits taken, I got the same result as you.

Since I tooked funny after uploading to Costco, I decided to print on using ProPhoto ICC embedded, one with ProPhoto and no ICC profile.

Then a fully edited ProPhoto image, with a final step of convert to sRGB with ICC attached, and one w/o.

I was quick to learn that the converstion to sRGB for printing at most common labs like costco, mpix is manditory. Their systems print 8 bit sRGB only.

The conversion isnt a problem, but I still and will always store and edit my photos using 16 bit ProPhoto RGB as my working color space in Photoshop when importing photos from Lightroom.

One thing that comes to mind when doing prints, is how much color or color change am I going to see when doing this conversion. I know my monitor cant display true ProPhoto RGB, but just like shooting in RAW, I dont want to loose and data that may come in handy when doing edits.

Ive also read something, somewhere that your working color space should depend also on what type of work you do. Ive been told for portrait work, its best to use sRGB.

For Product, landscape, and other things like that, aRGB or ProPhotoRGB would be best.

Can anyone confirm this?

Stealth, maybe you're referring to my post from two days ago (scroll up several posts). It talks about what space is best suited for a particular type of photography. The sRGB space likely applies to most of the work that most of us here do.

Most labs want sRGB. You may give them something else, but they will disappoint you with their results.

sapearl,

I applogize, It was from your post on page 1. Ive been reading so much about I forgot that I read it on my own thread lol.

I find this topic very intresting, and more I read about color management, the more I understand how important it is to learn. Im just trying to see what you guys are doing in your workflow. Why, when, and how.

The first one is ProPhoto RGB according to the EXIF data (read with a hex editor as Opana EXIF reads "uncalibrated" if its not sRGB)

and if you take the first one, open it inside photoshop, 1, the colors are corrected since the program knows how to display that color space.

and two, is another way to confirm the prophoto color space is embeded.

Wow,

I just noticed that opening the prophoto image inside photoshop or lightroom, the colors and everything looks WAY better. The gradations and all that stuff just look cleaner, but the sRGB convert looks harsh.

Maybe it is better to use sRGB for portraits.

That's OK.... been there, done that more times than I can remember .

There's so much useful information floating around here it's often hard to remember where you saw a helpful tidbit
