Seeking interest in Color Modes for Iridient RAW Developer?

[Brian Griffith]

I've had a couple email requests for color mode support in RAW Developer and I'm trying to gauge the level of interest for this. No guarantees, but I think I can mimic the SPP Color Mode styles pretty well with some custom ICC profiles for the various Sigma models based on X3F file metadata.

So if you're interested in custom ICC profiles that would give SPP Color Mode type styles let me know the camera model(s) and mode(s) (Neutral, Standard, Landscape, Vivid or Portrait) you're interested in.

Thanks!

Those are kind of interesting, but one thing I'd be interested in seeing was a specific mode for handling IR files - but taken with and without a real IR filter.

RAW Developer should work terrific with IR! Obviously some changes from the standard image defaults are going to be necessary and though I don't do any IR work myself, in my limited experience I'd say the "IR" look is very much a personal preference, from virtually complete monotone to tinted monochrome to various levels of color tones. The IR filter used will play a big role as well. I don't know that a single "mode" would be of any use to more than one person using one particular IR filter?

All the low level control is there to handle whatever specific filter you are using absolutely however you want... From completely custom individual channel control (RGB levels) over white balance to custom ICC profiles to fully editable individual color channel curves. If you want strictly monochrome output there's a nice set of "B&W" conversion options in RAW Developer under the "B&W" tab along with easy slider based tinting for duotones, tritones and even full blown custom RGB tinting curves (can load Photoshop curves into RAW Developer as well...).

What's missing for your IR work?

Best regards,

FWIW, I almost exclusively use Standard with my DP2 and Neutral with my SD15. If the modes worked as well in SD15 as in DP2 I would probably have used Standard there too, but they don't, they are clearly broken in SD15 and DP1x. All other modes than Neutral add around 2/3 stop brightness and 2/3 stop contrast in addition to the color change, both in-camera and in SPP. I wouldn't copy that bug if I were you

Brian, I'm with Kendall. The one thing I can add is that colour would not be a critical feature for me in an IR mode as that could after all be added in retrospect simply as an overlay in PS using the layer mode such as multiply or overlay etc.

how about fixing the brutal tendency of ca with the sd1 x3fs
in a way acr or silkypix handle this.
that´s prio1 imho everthing else comes second.

Still not clear what missing feature your'e looking for in an "IR" mode? If you're just looking for a generic monochrome IR style there currently is an "Infrared" preset option for the channel mixer on the B&W tab. Check the Convert to B&W checkbox, choose Channel Mixer from the top popup and choose Infrared in the Presets popup. This isn't designed to work with a particular filter or anything it's just rough approximation of an IR type look using the mixers... Once you get into specific IR filters though I think there are just too many options too much variation in personal preferences for much general use.

You can make your own custom settings setup and then save off a settings file named "IR Mode" so all that it would take to enter "IR Mode" was pick that setting from the popup menu, one step.

Thanks Brian, Kendall & Jim

Though I have no knowledge in this ICC business I am happy to step in line & start learning

I am interested in both UV & IR photography with the Sigma cameras. I have the SD15, which is difficult with UV & IR photography without live-view, but I have a DP2 without the internal hot mirror & it is an excellent camera for UV & IR photography.

There are issues that I have no understanding of, with colour rendering in UV & IR.

I have learnt to cope & accept, the IR processing to mono. I haven't delved into colour channel swapping in IR yet.

UV is proving difficult with the Foveon sensor for me. In UV photography IR contamination is an issue & seems to be more pronounced with the Foveon sensor & it appears to be more receptive to IR responses ? The Foveon sensor has a good response to a mixed image with both UV & IR. I have just now trying again to get better results with UV & have added three different hot mirrors together with the UV filter to eliminate the IR contamination & I am getting close to a pure UV response, but still some minor IR is showing ? The hot mirrors I am trying are passing UV & blocking IR. The Sigma hot mirror blocks both UV & IR.
I am hoping that Seng enters this discussion too Please

CA correction and other lens corrections (vignetting and distortion) are pretty much right at the top of the priority list for version 2 and a popular feature request. This stuff has all been in progress for a while now.. hopefully after Photokina the flood of new cameras this year lets up some and I'll have more time for finishing up some new functionality.

Thanks for the heads up, Brian. Disregard my previous jibberish.

Oh, I have just realised that Brian is with Iridient Digital & Raw Developer & it is Mac based :-(

Brian,

I read with interest, your quick tutorial that you gave to Jim (jrdigitalart) to help "see IR" (in B&W).

I wonder if you have a similar workflow to help me achieve an equivalent of the SPP "X3FillLight" adjustment? I'm currently using a combination of all three "adj tab" variables (and I can't remember their actual names because I'm at work, not on a Mac)... but I think they're 'brightness shadows', 'brightness midtones' & 'brightness highlites'.

Is there another way of recovering the hidden information from the shadow areas within the X3F?
Regards Pom

I too would like to know if there is an x3 fill light adjustment as it's a great feature that I use in spp.

Not super similar, but probably the closest RAW Developer adjustment to "fill light" is the "Shadow Fine Tune" slider found on the In tab of RAW Developer. Much more subtle than fill light... Positive values will brighten the deep shadows, negative will darken. The "Brightness Shadows" slider on the Adj pane can also be used to easily adjust the shadow range.

Mixing Shadow Fine Tune with Exposure adjustments and then some fine tuning of curves and/or the brightness sliders would give the most control over shadow tones.
