![]() Whether you use TIFF or PSD makes no difference. This really really sounds like you are exporting from Lightroom as an 8-bit ProPhoto image, which may be the default setting in LR just as it is in ACR.Ĭheck that your Preferences are set correctly. Thanks for your calm and helpful response to my post! I haven't tried softproofing so will check that. I do have the same versions of Photoshop ACR and Lightroom RAW engine.The export to Jpeg is sRGB. maybe there's something funny going on in ACR? I might try rendering using Lightroom's RAW engine to see if that helps. When I save it in Photoshop, it saves a TIF. I guess Lightroom passes the settings to ACR and ACR renders it in Photoshop. It renders using ACR using the settings that I have set in Lightroom. Try sofproofing your picture in lightroom with the profile you export it and see if posterization is visible. When you export your photo in jpeg, what is the color profile of the exported photo (srgb)? Even though Photoshop is set to Procolor RGB, if the export is in SRGB, then you don't have any advantage working in Procolor RGB in Photoshop. If second option : Verifiy what is the default profile whet Lightroom export the picture in tiff. If first option :Do you have the same version of Photohsop ACR and Lightroom Raw engine ? How do you transfer your photo from lightroom to Photoshop ? Using photoshop ACR or rendering the image in Lightroom (which saves it in TIFF) and opening it in Photoshop ? I took a screenshot from the LR develop preview window and saved it as a Jpeg and got no color shift, and an acceptably low amount of posterization. I don't understand what the problem is with the Jpeg export. Result? Posterization in the dark background, very visible, with an ugly blue color shift, also very visible (to me, anyway). No adjustments other than color balance and Camera Profile. Problem 2: LR RAW + Vignette -> Export to JPG I thought this pathway was supposed to be cleaner that this? F'ing posterization and color shift is still there. Thinking it's just a weird display problem, I save the file as a 16-bit TIF and open in LR. Picture opens in Photoshop and some of the darker areas of the background show posterization and subtle color shift. Edit in Photoshop is set to ProPhoto RGB 16-bit TIF. I need to extend the background in a couple of the shots so I choose Edit in Photoshop. I set the white balance, choose a Camera Profile. I have a set of portraits I took with a dark background. I'll post a few pics later when I get home. ![]()
