Software

displacement activity I

in Post-processing , Tuesday, December 11, 2018

I’ve recently been going through some kind of phase where I’m reassessing a lot of my work. Initially this was on an aesthetic level, but somewhat inevitably technical considerations started to intervene. First of all, I have been trying to get a little more disciplined in my picture making. Although I like to think that I’m pretty much on top of the basics of using a camera, I have tended to be a little indisciplined in how I apply this knowledge. This then leads to, for example, photos with too much, or too little depth of field, because I was too lazy to think about optimising aperture. It all came about when I started to make prints of some of the recent series of woodland photos I’ve been making. In turn this led me to making a number of “test” prints (to be perfectly honest, I probably don’t make any other kind). And so I noticed that the colour in these prints was actually a bit weird, and so _then_ I just had to re-profile the paper, which more or less fixed the issue, but used up all my supplies. And left me wondering how my previous carefully created profile had “gone bad”. And off we go again.

Untangle II

“Untangle I” - the photo that led me to re-evaluate my printing

Or not - prompted by an article I saw recently, I wondered if maybe it might be a good idea to revisit ImagePrint by Colorbyte Software. I used to use ImagePrint with my Epson 2100 printer, but when this died, and some 8 years ago I splurged on an A2 Epson 3800, I would have had to upgrade my ImagePrint license, and I couldn’t afford it. So I bought a Pantone ColorMunki Photo kit instead, which allowed me to profile any printer paper I wanted. Of course this was not the only option: many paper manufacturer profiles are actually more than close enough, and if they’re not, various service providers can create custom profiles for a given paper and specific printer. But of course I wanted to do it all my own way, and now I think about it, I’ve gone through at least 3 printer profiling setups over the last 15 years or so, none cheap.  And in fact even with dedicated software and hardware, colour science, which this is an application of, is seriously hard and time consuming, apart from being a money drain.

ImagePrint on the other hand does absolutely everything for you. It includes a custom print driver which brings a number of tangible benefits, from more accurate colour to saving paper, and a huge library of expert print colour profiles tuned not only to printer/paper combinations, but also to different lighting conditions. The basic point of ImagePrint is that it offers 100% reliable, plug & play highest quality printing. So you can just forget about all the technical complexities and just enjoy the creative part. This to me is quite enough to justify the fairly high price, but on top of that there are myriad additional features which offer significant advantages in various printing scenarios.  So I renewed my license for the latest version, “ImagePrint Black”, and ever since I’ve been printing a lot more, with no test prints required.

That solved my output problems. Next up was the input. I had been working on a set of photos recently for my 2018 calendar, and revisiting these I noticed that one of them was not quite right. This was a photo of an iceberg, which look fairly spectacular, but after I printed it (see above) I realised it was all a bit too, well, blue. So once again a trip down the rabbit hole of Raw conversion software beckoned. I decided to download a trial of the latest version of Capture One, v11 (now they’re on v12), and opened a few iceberg photos. One of them, not the one that had initially sent me into a spin, really shocked me: Capture One appeared to be showing textures completely missing in the Lightroom interpretation, and better fine detail as well. I cross-checked in Exposure X3, and in Iridient Developer, and the variation across these gave me the clue I needed to narrow the gap - it was simply a case of reducing the exposure, which in Lightroom seems to have a complex relationship with brightness. The much more involved Capture One default processing had, in this case, given better results.  As for the fine detail, well, there, at least with Olympus ORF files, the current iteration of Lightroom cannot match Capture One, or indeed the new Exposure X4. Both extract more real detail, although frankly only us pixel peepers would notice in almost all cases. But this comes with a price with Capture One, as any kind of noise reduction coupled with sharpening gives a horrible plasticky effect in recent ORF files. This is nothing new - I noticed it with v8 and it was just that made me decide to give up fighting and submit to Lightroom for once and for all.

“float” - the photo that used to be far too blue

However, Capture One has another major card up its sleeve, at least for me: the luminance curve. In Lightroom pretty much any change to contrast, by direct slider or by curve, has a major effect on saturation as well. Apparently this is by design, and it is stubbornly maintained, but personally I hate it. You can compensate by reducing saturation and/or vibrance, but first, this is imprecise, and second, why the hell should one need to? This naturally led me to the realisation that I should just be more disciplined with applying a previous strategy: do the Raw conversion in Iridient Developer, which is far less heavy handed, has not only a luminance curve, but also a chroma curve, and delivers the best detail and sharpness of all, then do the rest in Lightroom. Iridient even includes a Lightroom plug-in to facilitate all of this.

So, after this bit of re-evaluation, I have ended up with a software end to end process (I’m not going to call it a “workflow”, this is fun, not work) which drags the absolute best of my pitiful 16 Mpix sensor camera, and starts to approach the delicacy I’m always aiming for in colour and colour transitions.  Having got those variables out of the way, I can now concentrate on choosing the correct f-stop.

Hello David, you might be interested in the new "Iridient O-Transformer", which instead of a TIFF would create a more malleable dng file to Lightroom…
