More on the Fuji 18-55mm zoom lens | Gene Lowinger | Fuji X-Pro1 | Scoop.it


After reviewing my images from my outing on the streets of New York, one thing is very clear to me. I need more time with this lens to get my zoom/longer focal length chops back to snuff.

Drat it! I guess I'll just have to go out and shoot a lot more. Just to recap what I said yesterday: the focus speed is very good at 18mm and 35mm but a little slower (not by a big factor) at 55mm, the IOS (image stabilization) works extraordinarily well so that I can hand hold at 1/30th second and get good shots, I miss not having the aperture indications on the aperture ring but as this is a variable aperture lens (f2.8-f4) those indications would be meaningless, and the lens hood mounting leaves something to be desired in terms of a secure fit on the front of the lens.

The images below were shot RAW, processed minimally in Lightroom and then put through my workflow with NIK filters. The first two shots below were at a focal length of 18mm, f6.4, and 1/125th second. Since I keep my camera set on auto ISO it varies - the first shot was at ISO 5000 and the second at ISO 6400. In my film days an ISO of 6400 would have resulted in practically no definition in the small details. The first NIK processing is with Dfine to manage the contrast noise, then into Color Efex Pro 4 to optimize the color contrast with my special (wink wink) tweaks, and lastly into Silver Efex Pro 2 for the conversion also with my special (wink wink wink) tweaks.

In the first two images, the woman on the right was quite striking looking (nothing gets my camera finger more twitchy than a pretty lady) and yet so sad.....

Demosaicing the Fuji X-Pro1 Part 4 | ChromaSoft

Demosaicing the Fuji X-Pro1 Part 4 | ChromaSoft | Fuji X-Pro1 | Scoop.it


Well, I wasn't expecting to come back to the topic of Fuji, the X-Pro1 and its X-Trans sensor. However, I have been putting a lot of work into the suppression of artifacts when demosaicing. A lot more work than I had intended to, but that's another story. This is for a new product that I hope to release in a few weeks time (several months later than I'd hoped). But I did stumble into a better understanding of the nature of the chroma smearing (or watercolor effect, as it has also become known). The previous posts about Demosaicing the Fuji X-Pro1 are here, here and here. In previous posts, I compared renderings from Adobe Camera Raw, SILKYPIX and Fuji's in-camera JPEG processing, as well as DCRAW and RPP. Finally, I compared those renderings to renderings from PhotoRaw, both in its "retail" configuration, and in modified form with post demosiac filtering. Practically, DCRAW and RPP were pretty much outclassed -- they use VNG algorithms that generate substantial zipper effects. In post three, I hypothesized that the chroma smearing effect that you see very visibly in the ACR conversion, and to a lesser extent in the SILKYPIX conversion, was due to filtering, possibly mean filtering post demosaic. I now think that I was probably wrong, or at least partially wrong - the effect is due to filtering, but not mean filtering post demosaic. Rather, it's as a result of filtering during the demosaic process itself.....
