An experimental journey

Posted in Art, Leica M9, Life, Zeiss on July 21, 2011 by sojournerphoto

A few weeks ago I travelled from Newcastle to Leeds by train and took advantage of the journey to experiment with some pictures , many of which have significant degrees of motion blur – through a train window at 100mph… This is one picture from York station that I enjoyed. I’m working on editing the set to something reasonable and will post a link to slideshow when I’ve finished. My first cut was quite long, around 40 pictures, and I am working through a thought process of how many to include. In a sense the question is one of greatest hits or a more immersive presentation that accepts pictures that do not stand on their own. My inclination is towards the latter, if only because memories of journeys comprise so many many impressions apart from the highlights. A bit like life really.

Monochrome inkjet printing

Posted in Film, Printing, Rangefinder, Zeiss on July 13, 2011 by sojournerphoto

I’ve recently managed to spend a bit of time making print profiles for a couple of papers and my Epson 3880 printer. The papers are Ilford Gallerie Gold Fibre Silk (an old favourite) and Fotospeed Platinum Baryta (a new to me paper that I like very much, apart from the price!). One area I’ve felt could be improved for some time is in setting ink limits carefully and separately for mono and colour printing. In colour printing it is often helpful to maximise the size of the printable gamut. It seems this is usually achieved through relatively high ink loads. However, maximising colour gamut often leads to difficulties with shadow separation that are very hard to address. This can be particularly frustrating in mono printing as the profile doesn’t just sort it all out for you!

I spent some time printing and measuring targets with different ink loads and eventually settled on using a setting with 20% less ink for a dedicated RGB profile for mono printing (or lower saturation colour) and have now printed a few prints using the full ink setting and profile and the low ink setting and profile. So far the low ink settings are working well to produce visibly bettter mono prints, with more shadow detail and an appearance of better linearity o smoothness through the whole brightness range. The prints appear slightly lighter, but my main independent tester approves the mono specific prints in every case.

Field curvature – or why the ZM C-Sonnar is soft in the corners

Posted in Rangefinder, Zeiss on July 1, 2011 by sojournerphoto


I was playing iwth the Zeiss ZM C-Sonnar the otehr day and noticed some significant curvature of field ide open and close up. No wonder the mtf is so poor* in the corners! This was taken at f1.5 (focus on the middle apple) and about 0.9m. Just look at the branch coming towards the camera that remains in focus right to the edge of frame!

 

* the mtf curve is a function of the lens’ design. The lens is one of my favourites, but this amused me.
