"RAW Developer (1.9.4)"



Does anyone have any experience with RAW Developer - a raw converter designed especially for the Mac.

It has some quite interesting sharpening tools, one of which uses the R-L Deconvolution method (and no, I dont really know what that means!), which was apparently originally developed for correcting images from the Hubble telescope. I have read that it is particularly suitable for removing the effects of an AA filter in a DSLR.

As I have ordered a D800, and not the "e" version, I was wondering if this might be a route to take to "claim back" some of the sharpness "lost" by the blurring effect of an AA filter?

Assuming of course that RAW Developer will eventually support the D800.

Anybody have any thoughts?

Thanks,

Chris

I doubt there will be an issue . Images from D800E and D800 are very similar in sharpness and resolution ( that I have seen ) at even 400 - 700 % . Current
Sharpening software can handle most blur or axis related sharpening .
I'm not losing sleep .

NO experience with RAW developer. But, the (1st?) Hubble mirror was shaped from a design which was dimensioned in metric, but fabricated in Imperial, (what ever we're in english unit- even England doesn't use them any more). They discovered the error early on after it was in orbit. - a big upload error- A time for a software solution to a hardware problem. Hence R_L 'Deconvolution'...

Also I have had a D7000 for 15 months. Same MP/sqin as D800. Similar issues (and a great camera), with lightroom (&cameraraw) detail sharpening is excellent. This will be better with the D800 as the AA filter is much more sophisticated, and LR4 will be out. Hitting the 'problem' from 2 sides...
best, jf

Thanks - actually I've never consciously had sharpening issues either in Lightroom or CNX2, it was just I had never heard about this Richarsdon-Lucy (R-L) iterative algorithm before before and wondered if it was worth changing RAW converters for - or perthaps using for some specific reasons.

I still don't quite know what is does differently! Can anybody enighten me? !

In general, a deconvolution algorithm attempts to reverse the effects of blurring when there is some knowledge of what is causing the blur. In the Hubble example, the polishing error was well-characterized, so by multiplying the image function by the inverse of the known blurring function, one hopes to gain back the original image. (This was done in software with some success before correcting optics were installed in a later mission).

The challenge with deconvolution algorithms is finding a reasonable representation of the blur function and the risk of introducing other effects such as halos, etc. while performing the math.

For what it's worth, Lightroom uses deconvolution when the Details slider is pushed to it's higher limits.

Thanks, Paul - a bit clearer now .. I think

I've downloaded a demo of RAW Developer and will compare it (especially in the sharpening department) with Lightroom 3 (and 4 beta).

No biggie, but the Hubble mirror construction error was due to a faulty measuring device being used and was not related to unit conversion. However, one of the NASA Mars explorers was lost due in part to a metric/imperial conversion mistake. In both cases, systems and management oversight played a bigger role in the problems going undetected and/or ignored.

Thanks, My memory is a faulty as the measuring device, I guess..
