Trying to process a scanned film...

Postby DDR » Mon Nov 25, 2013 4:24 pm

Once I decided to try large format (flat film) photography, I tried to process a scanned TIF file with BWStyler. I found that most options required for HQ development works properly. However the film presets do not make any effect. They remain indifferent to the scanned (greyscale) image. I guess this is because they target modification of a colour source...

But!!! Take a moment, please. When I opened the BW scan with Lightroom, BW presets I own in my collection work properly. That is, they change the scanned source in the same manner as they change a digital negative.

My questions is as follows. If making film presets for Lightroom on the basis of BWStyler film presets, will these LR film presets work properly with a scanned (greyscale) source, or not?

Thank you for answer -- D.

If you open grayscaled images, neither BWStyler nor Lightroom can do adjustments that are based on color. Only brightness and contrast adjustments work. So I do not understand why you wrote that adjustments do not work in BWStyler but in Lightroom. Some adjustments in BWStyler that do not rely on color, still work with grayscaled images. But I guess BWStyler offers more color-based effects than Lightroom, so you probably got a wrong impression.

If you let me know exactly which effects of BWStyler do not work and which effects work in Lightroom, I can better explain why.

I do not see any difference between BWStyler and Lightroom presets that produce a similar effect.

1. I tell only about "BW Film" option which is the upper option in Photography Mode or in the menu Preset. When opening a scanned (greyscale) source, setting up a film does not change the image. At least so that it could be visible for me. The same no change appears on digital sources, if they were previously converted to greyscale by BWStyler then re-opened being greyscale images.

2. All other options work properly on greyscale scanned source. I found this even a year ago when started to use BW Styler. That is this is not something of the current version of it but is something principal maybe.

3. By the way, once I open a greyscale source (no matter that a greyscaled digital file or a scan) with Lightroom, I see significant change with the film presets which are respective to the chosen film. Both those presets sent on you and also VSCO film presets I tried on another computer.

4. Once I open even a low-colour image with BWStyler, the film presets embeded in it start their work in full power.

5. Silver Efex film presets work on greyscale images but converts them from 16-bit greyscaleTIF to 16-bit RGB TIF before to open. I converted the BW source to 16-bit RGB (no matter, scanned or digital). However after that the BW film presets still do not make any change...

I think the effect you are seeing in Lightroom with your film presets is produced by other effects and not by the eight sliders of the HSL/Color/B&W group, which correspond to the BW Film options in BWStyler.

If you choose a film preset from the Film Grain and Development preset groups in BWStyler 2, you will also see an effect on grayscale images.

You are right, Harald... Of course, film grains and the development sliders work properly (as well s all other presets in the list). Thank you very much for the explanation.
