Lightroom-Photoshop integration Workflow

Recommended Posts

Hello Damien,

I’ve just discovered  your  site, a real source of solid information concerning also the workflow.

I have scanned  thousands of 35 mm slides (Kodachrome, Ektachrome, Agfachrome, Fujichrome) getting tiff images 16 bit with a proper color profile embedded. Most of them show grain in the light areas and are quite underexposed.  I would like to process them most in Lightroom. Now  I have a main question.

It seems to me that for a scanned image some Lightroom tools dealing with the tonal range, the sliders Black , White  and WB, are not the right approach , it would be better to perform such edits in Photoshop. Another issue is the reduction of the grain: the denoising tools of Lightroom are not intended to deal with the slides grain.

I can see two ways:

     a) Going from Lightroom to Photoshop (CS6 or CC) with  all the edits (framing, tonal range, curves, saturation, denoise, perspective etc.), make tuning of Black and White points in Photoshop (including the color cast correction), remove the scratches  and then go back to Lightroom (tif with  levels) ? Or

b b) To quit Lightroom after framing, enter Photoshop to adjust the black, white point , white balance, remove   the scratches, reduce the grain appearance, then go back to Lightroom to carry on the editing to the completion ?

I think that in the first case the processing would be faster , presets for similar slides can be applied, but all the edits should be based on a tonal range not accurate.


What do you advise for an effective workflow?

Thanks in advance for your clarifications

Sure. Attached are 4 slides, scanned by Coolscan 5000 16 bit 4 samples, each one in two versions: with scanner profile embedded and converted to sRGB working space.

From your previous post I understand that the round trip from photoshop to lightroom is not advised , but technically is possible and utilized in many circumstances. May I ask wich are the con's? What about the reduction of the grain ?

Sir, Lightroom isn't even the best workflow for raw files.  It's DEFINITELY not the best workflow for scanned files. Use Bridge.

But yes, I would suggest noise removal, as well as other adjustments such as Exposure and White Balance, in ACR before proceeding to Photoshop.  The effectiveness of the noise removal will depend on the uniformity of the noise, I figure.  Some extra care, eg with Dust & Scratches filter, will likely be needed in PS as well.
