Not sure on the settings in adobe camera raw I've just changed them to

ProPhoto Rgb
16 bits
300 pixels/inch

I'm hoping to get a canvas printed soon so wanted to get my starting point correct

TIA Jack
 
ProPhotoRGB is an exceedingly wide colour space. In fact it's too large for any monitor or printing device to reproduce the full range.

If you want a large colourspace to work in then I'd opt for Adobe RGB. It's smaller but much larger than the majority of monitors and printing devices can accommodate.

The other settings are fine for editing, but you'll probably need to opt for 8 bits for printing and maybe even use sRGB as the colour space. Best to check with the company that are doing your printing for you as to exactly what they require

i,m not sure but it depends which photo editor you are using, in elements 6 i can only use 8bit, in lightroom i can use 16bit. hth mike. edit:- in elements it asks you to convert to 8bit if 16 is set.
 
Thanks
I've changed it back to adobe rgb I'm using PS4
 
Also worth mentioning that there's no point processing in AdobeRGB if you're shooting in sRGB... if you haven't already done so, check that your camera is also set to AdobeRGB.

If you're processing in AdobeRGB... then yes. But it's only worth working in AdobeRGB if you carry it all the way through your workflow to print.

If you're publishing anything to web, then sRGB displays better. So in that instance, either stick to sRGB throughout or convert your AdobeRGB images to sRGB when saving for web.

Not confusing at all is it! :D
 
If you're shooting RAW it doesn't matter what colour space you set the camera too.. RAW ignores colour space settings and most others since it's really just a straight data dump from the sensor with no settings applied. Thats what ACR is for, to adjust all the settings to your liking, not what the camera thinks it should be, like it does with shooting jpeg. (my own limited understanding of RAW, any mistakes are my own <G>)
 
Now I'm confused Lol

so it doesn't matter what setting I use when shooting Raw :thinking:
 
I think Myrdhinn is right. The Raw Converter makes that choice so you can convert to whichever space you want and then make another conversion in a different space - it is raw data after all.
 
So I look at what the printer wants then set this in acr

can I change it if I've already edited the image in photoshop

thanks for all the help
 
Not quite. When in ACR you make adjustments you wish to get a pleasing photo, then send it to photoshop to print or make further adjustments with layers or filters (you don't have to use ACR to make adjustments, you can use photoshop instead and just use ACR to import your raw file into PS). In photoshop is where you'd set your colourspace for printing. Most printers use srgb except for entry level pro and pro printers. Example, my Canon Pro9000 MK II can print either 8bit or 16bit and has a gamut wider than srgb so usually I print srgb in 8bit and argb/prophoto in 16bit. If the image has been already edited in PS you can only change things if it is a .psd file. Once its saved as jpg any changes is destructive and you can't go back to raw nor will resaving as psd allow to undo any editing that was saved under the jpg file.
 
cheers Peter

I thought you had to set the colourspace in Acr I've now just found in PS convert to profile

Sorry for the daft questions I'm not sure what I'm doing at all, I want to get a canvas printed by http://www.snapmad.com/ do I convert profile to sRGB in photoshop I have it saved as a psd file or do I open raw file again set the correct colourspace and redo my adjustment layers in PS
 
Since snapmad requires an 8bit jpg or tiff srgb file, once your photo is in photoshop, convert to srgb, and edit to your satisfaction, don't forget to flatten all layers if you use adj. layers etc. before saving, resize per snapmad's instructions for image size, then save as a jpeg. Hopefully someone else more knowledgable will chime in since Ive never used an online printer service before.
