True Colours

roses are blue, violets are green

in Post-processing , Friday, April 23, 2021

Colour is a funny thing.  Online forums and photo geek sites are full of self-appointed experts droning on about “color science” and generally talking total rubbish. For a start colour perception is both physically and culturally subjective. Our eyes are all slightly different, and our brains process signals in slightly different ways. The naming of colours is subjective in various ways. What I call dark orange somebody else might call red. And the colour I see with my eyes is often different to the colour I see on my camera or computer screen. And let’s not even get into prints.

So, buying a Hasselblad X1DII because it captures “more accurate colour” was possibly not the best idea I’ve ever had. Of course, Hasselblad has its vaunted “Hasselblad Natural Colour Solution”, which “was developed for serious users who demand the utmost colour accuracy”. But accurate in which sense? Maybe to a reference colour chart, which is all well and good, but it doesn’t help me much if I’m partially colour blind (I don’t believe I am, but who knows?)

Generally I don’t have too much issue with colour accuracy. In fact I’m more concerned with colour gradation. But there is one area which has always intrigued me, which is how cameras see flower colour.

Way back I had big issues trying to photograph poppies with my Olympus E-1, reported in one of my earlier posts on this site. Over time I’ve noticed that colours that to me visually are in the pink to magenta range come out blue. Some shades of yellow, such as wild primula, come out almost white.

So, I thought I’d do a little test on my thriving wisteria. To my eyes, the flowers are shades of lilac and purple, with some white and yellow tints. But on screen, in photographs they tend to come out more blue. So, I thought I’d see what the Hasselblad Natural Colour Solution would make of this. I lined the X1DII up on a firm tripod, then switching it for the 3 other cameras I use, the Olympus OM-D E-M1 Mk3, the Ricoh GR II, and the Sigma dp0. I used the 45mm f/3.5 lens on the X1DII, and the 17mm f/1.2 on the Olympus, these both closely approximating 35mm in reference terms. The GR has a fixed lens approximating 28mm, and the Sigma’s lens approximates 21mm.  I’m only really interested in colour here.  So, I loaded all 4 into CaptureOne, with minimal processing (the Sigma and Hasselblad images were converted to 16 bit TIFF via their respective proprietary applications. For the Ricoh and Sigma I tweaked zoom levels to get a rough match.

Well, the results are a bit disturbing. Of course you can’t really see a lot here, but from my subjective standpoint the best of the bunch at rendering the flower colours is actually the Olympus. The Hasselblad is close, but particularly in lighter areas in shifts towards blue (see on the left, and top right). The Ricoh is not bad, but a little under-saturated. The Sigma is in a world of its own, although if you look a detail rather than colour, it makes things a little awkward for the Hasselblad.

Maybe my eye/brain combination has some trouble distinguishing certain shades of blue? I don’t know, but on this unscientific and very specific sample, the Hasselblad Natural Colour Solution doesn’t score a home run.


Levadas: a new gallery

in Photography , Saturday, April 17, 2021

I’ve just published a new photo gallery, “Madeira: Levadas”. This one has been a long time coming. I’ve reprocessed all the photos at least twice, in different applications. This final selection comes from Capture One, and some of the photos benefit from the new ProStandard profile for Olympus E-M1 Mk II, which makes a noticeable positive difference.

Levada photo

To quote myself:

“Madeira was a long-standing fascination for me, but I never really new why. After finally visiting for the first (and second) time in 2019, I now know. The dramatic landscape criss-crossed by epic artificial water channels - the “levadas” - hand carved out of vertical precipices and disappearing into mysterious tunnels is like no other. It isn’t easy to capture the feelings that exploring the levadas gives in a photograph, but here is my attempt so far. And Madeira has plenty more to offer. I’m amazed that it isn’t up there with Iceland as an over-exploited destination. but I’m relieved it isn’t.”


Deep Forest

exploring the backlog

in Photography , Wednesday, March 03, 2021

One upside of being largely unable to travel outside of my immediate area for the last 6 months is that I have been able to spend some time reviewing and refining my huge backlog of photos, trying in some way to extract a portfolio.  Although even this gets tedious at times, and finding the motivation is not always easy, I have made some progress. Largely pushed by the Lightroom v10 debacle, I have now fully transitioned (back) to Capture One and I’m finding it very rewarding. There are some workflow drawbacks, but the degree of control in Capture One is vastly superior to that in Lightroom. This does mean that I have to process my Hasselblad raws in Phocus, but that’s not too much of an issue.

I’m also doing a lot of printing, concentrating on some specific photos.  The one presented here has been at the back of my mind for some time. As far as I’m concerned this is a 5 star photo. It shows the forest wall rising above a waterfall a little about the source of the Levada do Rei in Madeira.

Levada do Rei

The scale is perhaps not easy to understanding from this photo. It was taken from quite a high perspective, at 30mm equivalent focal length. Everything in the picture is bigger than it looks. It is easier to understand on a print, and I’ve printed this at A2 size.  I believe it is due to a slight lack of depth perception which comes from the micro Four Thirds sensor.  It was actually from my two trips to Madeira in 2019 that I started to find I was hitting the limits of m43, not only from this depth perception issue, but also in terms of far distance definition, and of dynamic range. This led me eventually to the Hasselblad X system as a complementary system.

Still, I enjoy this photo very much, and the Olympus E-M1MkII and 12-100 lens enabled me to take it. The Levada do Rei is quite an easy hike, but others are less so (the terrifying - but beautiful -  Levada do Norte for example), and I’m not sure even now if I’d take the Hasselblad system on such a trek.


Olympus M.Zuiko ED 12-45mm f/1:4 PRO review

well, my idea of a review, that is

in Product reviews , Wednesday, July 22, 2020

So, here’s a gear review. It’s not tongue in cheek, nor is it sarcastic, but it is purely subjective, is grounded solely on my own needs and desires, and has absolutely no measurements or “tests”.

Drm 20200722 EM520060

I didn’t need the (deep breath) Olympus M.Zuiko Digital ED 12-45mm f/1:4 PRO lens. I’ve already got far too many Olympus lenses, including the near-overlapping M.Zuiko 12-40 f/2:8 PRO, and the M.Zuiko 14-42mm F3.5-5.6 EZ (“AMATEUR” I assume). And of course I don’t actually “need” any of this stuff. However I have long wished for Olympus to break out of the “high quality lenses have to be fast and heavy” mindset, and offer smaller lenses that do not compromise on quality (either optical performance or handling). To some extent they made a move towards this with the 12-100mm f/4 PRO, although nobody would describe that lens as small or light - even if relatively, it is. So, given all of this, when this 12-45 PRO was announced, I was interested.

The new tiny 12-45 f/4 PRO versus the giant 12.40 f/2.8 PRO. Take your pick.

While the rough direction of my photography tends towards relatively exotic travel, especially the higher latitudes, clearly I don’t do that everyday. But photography is part of my everyday life, and while I don’t necessarily share much of my day to day, mundane photography, I still do it, still enjoy it, and it keeps me in practice. So, having a compact but quite nice and high-ish quality system is enticing. On the camera side, the OM-D EM5 Mkii fits the bill, but the existing 12-40mm PRO lens is a touch unbalanced on that body, especially without the various bolt-on grips and baseplates.  And the 14-42 EZ isn’t very inspiring, at least my copy isn’t, although it was probably better before it had a fairly traumatic trip around Colombia.

Yes but. The 12-45 PRO lens is quite expensive, and from my point of view, hardly essential. However, when shopping at my favourite online store the other day (for mosquito repellent) I noticed a very interesting “open box” offer for the lens, some 30% off standard price. At that price I thought it was worth a go, especially right now it might be a good idea to buy up Olympus lenses while we still can.

So here it is. I’ll skip the unboxing ritual, although it is worth pointing that this lens comes with a rather nice soft cloth wrap, rather than a clumsy pouch, which could actually be useful. As opposed to all other PRO lenses (and a number of AMATEUR ones), it has no “manual focus clutch”. This is no big deal - in my opinion this is only really useful on prime lenses. I can switch to manual focus on the flick of a switch on the camera body anyway. Otherwise it is clearly a member of the PRO family, both by design and heft. Addressing the number one question, is it really that much smaller than the 12-40 PRO? Well, side by side there is less in it than you might expect. But when mounted on the EM-5 MkII, the difference is very noticeable. While the 12-40 PRO unbalances the handling (to some extent, let’s not exaggerate), the 12-45 PRO feels absolutely perfect.

So, I bolted the the Olympus M.Zuiko Digital ED 12-45mm f/1:4 PRO lens on the front of OM-D E-M5 MkII body (sorry, I seem to be drifting slightly towards the Sarcasm Sea here, I’ll try to stop it) and took it for a brief walk while waiting for a doctor’s appointment (I’m fine, thanks for asking). Unfortunately - or not, who knows - I didn’t notice that the camera was still set to use a custom colour setting I’d been playing around with, and to record in JPEG. Just as well I’m not into “tests”.

Drm 20200722 EM520054

My initial impression was just it was just seamless to use. It fits perfectly onto the E-M5, and is a really nice, flexible walk around lens. The zoom range is very useful, and it does have one special trick up its sleeve in that is has a very short minimum focus distance of 12cm at all focal lengths. This gets close to macro range. It’s sharp - at least as sharp as the 12-40 PRO - and as far as I can tell at all focal lengths, starting from wide open. Of course, wide open is “only” f/4, which some bespectacled angry geek will pop up and correct to “f/8”, but that’s part of the design. Frankly f/4 is good enough for me. I’m far more often struggling getting enough depth of field rather than complaining I’ve got too much.  Of course it could be brighter, but then it would be a 12-40 f/2.8, and, well, start at the beginning if you didn’t get the message on that yet.

Drm 20200722 EM520062

A close focussing test.  At focal length 12mm.

I’m pleased I bought this lens, although the special price had a lot to do with it. It has its own niche, and for me that will be getting glued to the front of my E-M5 MkII. This, and just maybe the 17mm f/1.8, will fit very nice into a corner of my small Domke shoulder bag, and be a perfect companion for casual photography. Which is most photography, for me.

Doubling down

and moving out

in Photography , Saturday, December 28, 2019

The frequency at which I updating this site recently hardly justifies the hosting fees, or indeed all the work I put into upgrading it some months back. This reflects my currently diminished interest in “engaging with the community”, where more and more I’m finding that an audience of 1 is all I need.  There’s nothing world changing or meme generating about my photography, so it would only be counterproductive, and probably depressing, to fish for likes and whatnot.  Although you’re more than welcome to boost my ego on Flickr.

Another brake on my visible creativity is my processing, in both a computing as well as a mental sense, of the too vast haul I brought back from Greenland in September. The problem there is that the overall quality is too high. It was really difficult to cull the stragglers when a very high proportion of the photos was pretty good, even if I say so myself. And to a reasonable extent I avoided repetition and taking “just in case” shots. This is problematic because I don’t have to time to edit thousands of photos, and I already have a significant backlog. On top of that, I’ve been busy planning another imminent trip, once again Deep South to Antarctica, with an Hors d‘Oeuvre of Argentinian and Chilean Patagonia. I’m kind of telling myself that the Patagonia leg will be focused on trekking, with at most a little vacation photography, but we all know where that ends up.

Which brings me finally to the point. My last few, far between posts have pretty much been about gear, and so is this one. After quite a lot of thought and dithering, I have decided to redouble my reliance on micro four thirds gear, and in particular Olympus. There is a significant advantage in polar regions to having two cameras, generally one with a wide angle lens and one with a telephoto, so I have replaced my older E-M1 (which did fine in Greenland) with a second E-M1 Mark II. How do I explain this extravagance? Well, lucky me, I work in a Swiss Bank, so I’m insanely rich, darling (well, really less rich than insane). And considerably more truthfully, the fact that the Mark I and Mark II have different batteries means more weight and bulk to carry, and the slightly different control and menu layouts are annoying.  The new Mark II came with a free grip from Olympus, which is also useful in Antarctica. And both, together with a set of Pro zooms covering a wide focal range, snugly fit into the camera bay of my fabulous Atlas backpack, which is perfect for trekking. So there we have it.

I expect the Sigma dp0 will come along too, although my objective of keeping weight down to 20kg + 8kg backpack for a 30 day trip is under quite some strain.

Regarding the Olympus stuff, I‘ve mentioned the mushy far distance effect which I dislike a few times. Actually I‘ve looked at raw files from other cameras, including medium format, and seen pretty much the same thing, it just sets in at a greater distance or higher frequency. Probably another aspect of the same root cause is a plasticky look which sets in on surfaces like exposed rock in certain circumstances. Processing software has an effect on both of these behaviours - I find Adobe Lightroom / Camera Raw to be the least bad. Interestingly the Sigma cameras seem to be free of these effects, as does film, so maybe it is a Bayer filter thing, but these systems have their own drawbacks.


This is what I mean by “mushy”.  This is a 1:1 screenshot, probably further damaged by compression, but maybe it shows what I mean.

Finally, does any of that make an iota of difference between a good photo or a bad photo? Of course not. But it can be annoying.

So, my objective now is to take as few photos as I possibly can, and to try to be aware of and work around the limitations of my gear. Oh, and to put a memory card in.

** I was hoping to fit in a “my favourite shots of the year” before heading off, but I ended up spending the time unpacking and repacking everything again.  I’m a hopeless traveller.
