Returned from a two-day trip to London last Thursday, with a couple more snaps I would like to share with you all.
In a contest on Leica's blog I had won tickets to attend a Gala auction at Christie's, at which a large set of landscape pictures were sold for the Positive View Foundation. Did not get to buy any prints myself (though I would have loved to get this Philip Jones Griffiths print), but at least I had the opportunity to shoot some more London pictures of my own.
I'm not quite done sharing Paris photographs, but figured I might as well start on London. I may also add some snaps from previous trips to London later, since I took so few pictures over this two-day trip.

I can't see your EXIF, Bjorn. Are you facing any banding at high ISO, in situations like this? It certainly doesn't look as if that's the case, but I heard that it occurs with the M9/M9-P sensor, as with my D700 in high ISO situations at night with point light sources

I am facing pretty severe banding issues, yes, mainly in the green (and yellow) spectrum. It's something I have to take into account while processing, but with the right adjustments to the color sliders it typically disappears. The circumstances under which it appears are quite unpredictable. Mostly it only arrises at ISO 2000 or 2500, but at the auction I shot one frame at ISO 1250 and it had similar problems. The second frame below is the picture (pulled the green and yellow sliders in ACR all the way to the right to emphasize the banding), along with the version I processed correctly to make the banding disappear (the careful viewer will notice some banding still appears in the hair of the lad, but that doesn't bother me enough to spend time getting rid of it).

    2. Whisper. Christie's, London, 2013
    Image

    Aperture: f/1.4
    Shutter Speed: 1/125th
    Sensitivity: ISO 1250



    Image

Obviously the dark lines on the people in the background would not normally appear, that's just because I processed the image in a more extreme way. When I'm not careful with the green channel in particular, the main band will show up. It is always at the same vertical position, and runs from the left to the middle of the image or beyond it (but never all the way across). If I weren't a black and white photographer, I would probably have sent the camera back to Leica. When processing these images in ACR for B/W, I can almost always get rid of the banding. However, if you're processing for color, I am sure it would take a whole lot more work to get rid of the green band running across the image.

Hi Bjorn,

There were reports that the banding issue was made worse by some memory cards. I can't imagine the mechanism if that's the case but if you have a few different makes/models of card to hand it might be worth experimenting.

Bob.

I might give that a go some time Bob, thanks for the tip. All my cards are Sandisk, but I do have a variety of models, with different speeds and capacities.

A view from the silver department of Fortnum and Mason. Quite a store, I wonder how Harrods is so much better known...

There are probably few things people do out in the open that look more stupid than taking pictures with a tablet... To each his own I guess.

Part of the lyrics from the song that inspired this set of pictures:

    The moon that lingered over London Town
    Poor puzzled moon
    He wore a frown
    How could he know we two were so in love
    The whole darn world
    Seemed upside down
    The streets of town
    Were paved with stars
    It was such a romantic affair
    And when we kissed and said goodnight
    A nightingale sang in Berkeley Square

Cannot think of a title for this picture. Any suggestions?

I like the last image a lot. It's a (very slight) shame there's another pedestrian in the frame which only slightly dilutes the image IMO.

I don't know if you know what "Cobblers" means in colloquial English, Bjorn? Maybe a play on words around that subject....

I sometimes get banding when I use my Panasonic 20mm wide open at night. Some luminescence noise adjustments in LR tend to fix it. I think it's sometimes specific to a particular lens. I know you currently only have one for your Leica though, so I suppose you have limited options.

Your images have a pleasant film-like grain to them and I assume you've not used any NR in post? The one of Westminster Palace has some more complex banding in the shadows at the bottom of the frame. I think that is easily solved with LR's NR features.

Thanks Phil. I do agree the man in the background should not have been there, but he ended up in the frame. If I had been a little faster it might not have happened, but I'm not that fast... :) I have looked into the different meanings of cobbler in English (suppose I should avoid using that word now), but have also gotten a good title suggestion from a friend on Facebook (Passing interest, which I adapted to Passing fancy).

Thanks Kimchi! I do not do any NR in PP, no. Quite like the noise the M9-P produces, and as you write, it gives them a bit of a film-like quality. I hadn't really noticed the banding in picture 6, but then that was so underexposed that I'm happy I got at least a bit of detail in the shadows (the Nike logo for example). I like to think that whatever I do in ACR could be done in the darkroom, and while I've never developed a picture in a darkroom (I want to though), I suppose that means I do minimal processing.
