My Velvia scanning process (or maybe just luck)

Following on from the 'Show us your film shots' thread, I've exported a couple of screenshots from Lightroom to share what steps I took when scanning my latest Velvia slides. I still find it hard to get consistent results with digital scans but I'm starting to realise that's as much down to my technique when shooting with Velvia as it is my digital process.

Anyway, Jao asked for some more information about my techniques so;

1) First scan output - I have both Epson Scan and Viewscan but tend to favour Epson's software as I've never seen any huge difference between outputs of the two. I have all options disabled and just stretched the levels out to each end of the histogram after the preview to drag out as much shadow detail as possible without killing the highlights. The basic settings are 48 Bit and 3200dpi, output as jpg (I've just realised that this is already cropped but the colour is as per the scan)

The first scan generally has a red/magenta cast but I've found it's best accepting this from the scan software instead of trying to correct it.

2) Import to Lightroom - I then imported the initial scan to Lightroom and applied a preset which I've created myself to remove the red/magenta cast. The bulk of this preset uses the Hue/Saturation/Luminance (HSL) sliders to remove the cast and get the image somewhere nearer to the finished colours. Whist the preset isn't a perfect job, it gets me somewhere close and just leaves me to 'tickle' the image to get it to the finished output. Generally, I've found that the saturation needs to be toned down a little so the shot doesn't looked overcooked and unnatural.

This is the shot after the preset has been applied. The blues are still too vibrant, even for Velvia!

3) Final editing - Each slide is different so the editing steps after the preset will also be different but in the case of this photo, the main work was with the Highlights/Shadows/Vibrance sliders along with a shift in blue and aqua saturation. I also cropped/rotated the image because I thought a square format would suit it better. After that, I removed some blemishes in the sky with the spot heal brush and finally exported the finished image.

4) Finished photo - Whilst there is still a slight blue hue on the white parts of the buildings that I need to edit directly in photoshop, I'm happy overall with this. I have a couple of other shots on the same film that have much stronger contrasts between shadows and bright skies so I haven't been able to get a consistent result across the frame using this method which is where it comes down to metering more consistently in the first place or simply moving to shoot from a better location or at a better time of day.

I hope this is useful for anyone else struggling to get consistent results from scanning Velvia with a flatbed scanner (I use a V500). Whilst I'm nowhere near consistent, each time I get a scan to look anywhere close to the amazing colours and clarity of the slide in my hand, I'm made up!

If anyone wants the preset, let me know and I'll put it into Dropbox. It's by no means perfect but might at least give a start point.

Cheers

Hope I haven't misunderstood the above, but I read it quickly and it appeared that you're scanning for 48-bit yet saving as jpg from the scanner software? This to me is contradictory - to maximise quality especially of an image that was destined to be processed further, I'd have saved as a tiff. I view jpg's as suited to certain end-uses, but less so for processing.

Can't the scanner in question output a RAW file? That might be even better as non-destructive Lightroom fodder. Then after adjustments, you can export as what you fancy for specific purposes.

You haven't misunderstood at all, I've been exporting as jpg from Epson scan as in the scans I've done I haven't found any huge difference in quality when exported as Tif or Dng. Whilst I potentially risk some artefacts as a result of the jpg compression, the increased scan time and larger file sizes are a bigger issue. You're right that I probably don't need to leave them as 48 bit though.

Nice one Steve, if I get round to scanning some of my old Velvia I am sure I can adapt the above to PhotoShop.

One reason I gave up using Velvia 50 was that the shodows used to block up like mad and it was a pain to scan. Hey Ho!
 
Steve, you wrote:

I use Aperture rather than Lightroom, so I'm trying to understand this. I've said before that I don't understand dealing with colour casts at all, and realise I've illustrated this by trying to use white balance to fix colour casts, possibly not quite the way it was intended I think. Anyway, I'm trying to understand this. I've got a block of color [sic] controls in aperture, with one set for each of red, yellow, green, cyan, blue and magenta. Each control has sliders for Hue, saturation, luminance and range. When I was playing about with my Velvia 50 scans, I did use the white balance control, and then went into the green colour control and reduced hue, saturation and luminance by different amounts. It seemed to work, but since I have no idea what I was really doing, it amounted to just fiddling about.

You are obviously doing this in a preset. Could you say which colours you tweak, and roughly how much? I appreciate your comment that it's only a starting point, but it would be helpful to my understanding.
 
Hi Chris. I saved my own Preset after tweaking the sliders to a point where the image looked 'almost' there. The screenshot of Lightroom below step two in my post shows the HSL sliders for all colours :0)

Thanks Steve. Basically you've left the hue the same for yellow, green, aqua and blue, upped the hue for red and orange (a control I don't have) and dropped hue for purple (don't have) and magenta. Saturation unchanged, luminance unchanged for all except magenta which is bottomed.
