Editing LR files in Photoshop

[ian in lancs]

I'm shooting raw portraits and fashion and importing into lightroom. I'm using a D800 at 14bit so the files are circa 40MB. Moving into Photoshop I've got PSD as the file format and AdobeRGB as the colour space (as per camera).

I'm printing A3 max and want decent quality on zoom in on a hi-res retina screen

I'm thinking to preserve the quality I should be setting 16bit and resolution of 240 but I'm ending up with PSD files of circa 200MB. Is that right? Am I going wrong somewhere?

When you've edited everything how you want it, save it as a JPG. Keep a copy of the PSD though until you're definite you don't want to make any more major changes!

Im asking whether the setting are right?

For best results; in Lightroom go to Edit-Preferences, go to the External Editing tab, set the first external editor to your version of Photoshop, TIFF, ProPhoto RGB and 16 bit, set compression to any of the three options (won't make much difference) and Okay it.
Once you've done your Lightroom edits and want to continue in Photoshop then right click on the file and go to Edit in Photoshop.
Do your Photoshop edits and save the TIFF file - it will be saved along side the original Raw file and will appear in Lightroom stacked with it.
You can now print from the file in Lightroom or any other program, or you can export it as a jpeg (or other file format) sized for whatever purpose.
Note; Raw files don't have a colour space as such - if your camera is set to AdobeRGB then this only affects in camera generated jpegs and the previews on its lcd. For web use its best to use sRGB jpegs as most browsers will cock-up the colours if you use AdobeRGB. ProPhoto is a considerably larger colour space than even AdobeRGB so less information is thrown away in the conversion from a raw file to other file formats, having said that if you don't use 16 bit files then ProPhoto isn't worth using. Lightroom's native colour space is near as dammit ProPhoto.

Edit; and yes, about 200MB is about right for a D800 16 bit TIFF or PSD before you start adding any layers.

It would be interesting to print out your 200Mb file onto A3, and then make a 4,000 x 3,000px hi-res JPG from it, and see if you can tell the difference.

I dont think so, I'd assume a 200meg file is about right. The question on whether you need to do that is separate though
