Catalan evening

Thursday, May 30th, 2019

It was around a quarter past five by the time the Catalan protest got going on the steps around Eros, and in mid-February this was sunset, though it seemed rather darker than this suggests. Of course with the amount of street lighting and lights in shop windows and traffic it never really gets dark, but the contrast between the brightness of the advertising display on one side of Piccadilly Circus and the opposite side of the monument was pretty huge, and the protesters seemed to be in very deep shadow,

Using the Nikon D750 and D810, with both set to ISO 6400 allowed me exposures of around 1/125 at f5.6 without flash, though these were deliberately underexposed by a stop or so to keep something of a night look.

I didn’t have any fast lenses with me – and don’t own anything faster than f2.8 for the Nikons, finding them too heavy to carry and unsuited to most of the work I do where wide apertures mean the depth of field is too limited, though there are times when a fast telephoto would certainly help. But apart from the cost of the lenses I’d probably find myself needing the services of an osteopath. Although the Nikon lenses are remarkably good wide-open, when possible I like to stop down just a little, and most of these were taken at 1/2 to one stop down from the variable maximum.

I used flash for about half of these pictures, with a Nikon SB800 in the hot-shoe, but still worked at ISO 3200 to avoid getting people looking like cardboard cutouts in front of a black background, making sure that areas too far away to benefit from the flash were still getting enough exposure from ambient light. Although normally I work with the cameras on the ‘P’ setting (but often altering the selected shutter speed) Nikon’s flash system doesn’t really work with this, and when using flash I switch to aperture or shutter priority or sometimes full manual.

Flash on camera is always a problem where important parts of the subject are at different distances from the camera, and sometimes I make use of the fall-off of flash away from the centre, angling the flash head away from the closer parts of the subject. But inevitably some, often considerable, burning and dodging is needed when processing the images. Even in those taken without flash the lighting was pretty uneven and some correction was needed. If I can tell which of the images was taken with flash and which without except by looking at the EXIF data I don’t think I’ve got it right.
