arnabdas Posted September 23, 2009 Share Posted September 23, 2009 <p>Curious to know what you all prefer for editing tiff scans of Velvia slides -- Lightroom or Photoshop?<br> Some of my scans are of dark colored early morning dewy subjects and exposed for the highlights, so the dark areas are pretty dense (not blocked, but very dense). The biggest challenge is to extract enough shadow details without losing "punch".<br> I am wondering if PS will continue to be the best solution or if investing in lightroom will reward me with additional opportunities.<br> As a backgrounder here's my scanning workflow -- I scan 16-bit linear (I use double-exposure for the dense slides) with input space= built-in and output space = Device RGB then I open in photoshop and assign Minolta DiMAGE Scan Elite 5400 II (Posi Linear) profile then do a perceptual conversion to ProphotoRGB.<br> From this point onwards, is there anything that Lightroom could do (to extract shadow details and processing in general) that photoshop could not)?<br> To reiterate (and to prevent the thread from veering off-track) -- this is not a general LR vs PS question. Instead -- this question is specifically regarding relative usability of LR vs PS as far as processing dark/dense slide scans are concerned.<br> Appreciate any insights! Thanks</p> Link to comment Share on other sites More sharing options...

The advantage of LR is all the edits are metadata and applied in the best order. That means you can use that processing engine and until you export the data, you’ve got less overhead than using say adjustment layers with pixels. But in terms of getting “more data” to work with on shadows, no, its not the same as providing Raw data to LR to handle the demosicing process on linear encoded data. </blockquote> </blockquote> Author “Color Management for Photographers" & "Photoshop CC Color Management" (pluralsight.com) Link to comment Share on other sites More sharing options...
roger_smith4 Posted September 23, 2009 Share Posted September 23, 2009 <p>I don't think there's anything that Lightroom can do that Photoshop cannot, but Lightroom has very good tools like fill light and its general color correction tools which work well for most images and are quicker (and take up less disk space) that doing it via layers in Photoshop. If you've got two or more scans of a similar scene and can transfer edits from one to another I'd say Lightroom is a huge advantage over Photoshop for saving time.</p> <p>Personally I use a similar scanning workflow to you and after I assign the profile (batch this in PS) I import the files into Lightroom for further refinement these days. I do things much faster than when I had a PS only workflow (even with custom actions I created).</p> Link to comment Share on other sites More sharing options...
mendel_leisk Posted September 23, 2009 Share Posted September 23, 2009 <p>Just for anyone not in the know: "16 bit linear" is a Minolta scanner software expression, and essentially means the file is gamma 1.0 (as opposed to something like 2.2), and it's histogram has been left as-is, not adjusted.</p> <p>Arnab, you might try using those files in a Vuescan scan-from-disk workflow. This was what I did, with close to 2000 slides, using the Minolta Scan Elite 5400.</p> <p>You will need the Vuescan "Pro" license to do this (worthwhile, in any event). Here's some info:</p> <p><a href="http://www.hamrick.com/vuescan/html/vuesc14.htm#topic11">http://www.hamrick.com/vuescan/html/vuesc14.htm#topic11</a></p> <p>In the above, you simply sub. your 16 bit linear file for the Vuescan Raw File. Works the same. I would suggest scan-from-disk with the input tab setting:</p> <p>Input|Image</p> <p>You can also try:</p> <p>Input|Color Slide</p> <p>And if you do the latter I'd suggest profile (in the Color Tab):</p> <p>Color|Generic Color Slide</p> <p>Any of the other profiles seem pretty horrible ;)</p> Link to comment Share on other sites More sharing options...
