A catalog for Sigma Files

Just some geeky tech stuff…

As a long term user of Sigma fixed-lens cameras (I was going to say “compact” but then glanced at the dp0 Quattro on my desk) one of the most frustrating things is the difficulty with browsing photos on disk. Sigma’s Raw formats are read by very few applications, and although Quattro cameras now support DNG, which makes life easier, this comes with the drawback of not being able to use Sigma Photo Pro (SPP) for raw processing. Many would say that was a plus, but in my opinion, the combined effect of the latest version of Adobe Lightroom’s poor rendering of the DNGs, and the big step forward Sigma have taken with Photo Pro v6.6 sways the balance towards proprietary X3F files. Honestly, if you’re going to go to all the trouble involved in using a Sigma camera, it seems pretty nuts to settle for arguably sub-optimal output.

So, I needed a solution. SPP’s file browser is truly dreadful. It has no facility for marking folders as favourites, it cannot peek inside a folder to see if it has no Sigma Raw files and thus exclude it, it has no standard metadata features, etc etc. It’s a real pain.

There aren’t many alternatives: my standard tool for cataloging outside of Lightroom is MediaPro, which I use for mainly for film scans these days, but in the past I used for everything. I’ve probably been using it in various incarnations for 20 years or more. The last significant update to MediaPro was under its original owner, iView, to version 3. That was in 2004 if I remember correctly. Since then it has been owned by Microsoft, then PhaseOne, and has benefited from almost no functional development. PhaseOne’s last effort, “MediaPro SE” brought only OS compatibility (supposedly) and alignment with CaptureOne.  MediaPro SE still has quaint menu items such as “Backup to CD-ROM”. So, the chances of MediaPro supporting X3F files are in the snowstorm in hell category.

But there is one last chance: iDimager Systems PhotoSupreme (PSU). I’ve been trying to get to grips with PSU for a while. Generally I found it a very frustrating experience. PSU has a bizarre User Interface, at least for one coming to it from an application like MediaPro, or indeed Lightroom. For me Version 3 was also alarmingly unstable - you do not want an application that you invest a lot of effort into to trash it’s database too often - and at times extremely sluggish. But it could read X3F files and extract the embedded JPG. And it had a lot of other promising but infuriating features. Nevertheless MediaPro was still more elegant and intuitive, after all the years of neglect. So I set PSU aside and struggled on with SPP’s browser.

Then came PSU Version 4. I was dubious at first, the upgrade price of some $100 seemed pretty steep, and I wasn’t that optimistic. But eventually I took the plunge, and so far, it’s working out pretty well.  With PSU, I can now import X3F files, catalog them, organise them, smoothly review in anything up to full screen, and compare several files using the Light Table. What’s more, with one click I can send them directly to Sigma Photo Pro. And after I process them in SPP, I can import the TIFs into PSU and bind them with their source X3F into Version Sets (basically what Lightroom calls Stacks, only more like Aperture’s stacks, without Lightroom’s bone-headed limitations). 

Here are a few screenshots to illustrate the various steps:

PSU Version 4 also has a reworked UI, which makes it considerably easier to get to grips with its modus operandi. It still has some rough edges though, and the developer (iDimager Systems is a one-man show, as far as I know) would do well to hire a User Experience consultant. Although to be fair probably that would not be commercially realistic. But all in all it works, and it has some very nice features, apart from the powerful Versions concept. For example, it can apply quite impressive approximate renderings to Raw files processed in Lightroom, CaptureOne and DxO PhotoLab. On the downside, it really is very inadequately documented.

But in any case, for me at least it is a really liberating experience to be able to use extensive Digital Asset Management tools on my Sigma X3F Raw files. I very much work with sets of photos, not individual shots, and the editing process (in the traditional sense) is actually more important to me than editing (in the digital photography sense). So PhotoSupreme is well worth the money, and the still fairly steep learning curve.
