Color shift on Enlargement...Help needed!

I sent a photo off to a lab to have it enlarged. (A red sandstone from antelope canyon)The photo was submitted with a tif document which had been worked on in PS 4 When I got the print back it had a color shift to browns and blues (no reds) I printed the photo on my printer (epson 1400) and it had the same color shift. I then did a print off the original CR2 file and it was "as viewed on the screen.
Both files appear identical when viewed in PS 4.
Any help would be appreciated!

What color space did you tag the print with before you had it printed?
Which lab did the printing?

SRGb color space
Adorama color print.
I did another print at home and changed print settings to have photoshop manage color settings on the print. This turned out much better.

Here's a link to Adorama's Color Calibration & Custom Correction page with color profiles freely available. You're not letting them color (auto) correct the image, are you?

And greetings from Cortez!

Also, most folks let Photoshop manage colors, rather than the print driver. I believe this is because you can choose any paper/printer profile, and rendering intent, rather than just those built into the driver. Not a big deal if you're using one of the built-in ones anyway. But, if you're going to do everything else in PS, including soft-proofing, why not let PS manage your color profile conversion as well?

I had a similar problem when sending a Tiff to Adorama a year or so ago. I blamed it on my own inexperience (with Tiffs, with LR which has a record of showing darker in print, and with an non-calibrated monitor) but I'm not sure it was "my fault."

Can someone confirm whether-- Tiffs on their own -- have all the adjustments made in pp or whether they require a side-car file to retain adjustments and not revert to RAW color/exposure, etc.

Marylynne,

TIFF files are a standard image file. They will retain all adjustments made in post-processing. Additionally, they will retain all adjustment layers, if they are not flattened. They do not require any sidecar files.

Note also, that unlike Adobe PSD or RAW files, which are proprietary, they can be opened in other image editors and image viewers.

Thanks Preston. That issues has been confusing to me. I hope I didn't hijack the thread with my tangent on the orginal poster's question. If so, my apologies to Richard.
