Mist, photo cropping and relativity

I've been using my relatively small DSLR body (Nikon D5300) and one relatively light and small lens (AF-S Nikkor 18-140mm 1:3.5-5.6G ED) as my walking camera for several months now. I'm relatively happy with the combination's relatively low weight, relatively high quality and relatively wide zoom range. If that makes me sound relatively unenthusiastic, I'm not. Bear in mind that I was raised in Yorkshire, a county where the compliment, "Not bad", is high praise indeed. Seriously, I'm very happy with the results I'm getting: the technical qualities of the sensor, camera controls and lens are very good.

However, the 1.5 crop factor (relative to 35mm) means that the lens' range is 27-210mm and that's not quite wide enough or long enough for me. Better would be 24mm-300mm. However, such a lens would be bigger, heavier, probably not as bright, and probably not as sharp. All equipment involves compromises and my reluctance to carry the Canon 5D2, 24-105mm and 70-300mm (which clearly does cover my desired focal lengths) means that sometimes - maybe 5% of the time - I can't get the shot I want using the Nikon. But, one of the benefits of a good 24 megapixel sensor is the ability to crop the image and simulate a longer focal length, so one of the shortcomings can be addressed.

I took today's photograph with a heavy crop in mind so I ensured the camera was well stabilised. I estimate that I'd have needed a 400mm (equivalent) lens to secure this shot. Yet, cropping has left me with a file that is perfectly usable for most purposes. It shows a view from near Herefordshire Beacon in the Malverns, looking across the low hills around the Severn valley. On our recent walk in that area the mist was clearing when we arrived but started to thicken again as we departed. I liked the colours and gradations in this composition, as well as the detail of the trees and the plumes of smoke. It reminded me of traditional Chinese ink and wash paintings.

In praise of small sensor cameras

Those who use digital SLRs often have no time for small sensor cameras. Not only do they lament the lack of control that compacts offer, they also bemoan their low-light abilities, the image quality and the difficulty in producing out of focus backgrounds - what is today called "bokeh". I use both a DSLR and a compact digital camera, just as for a couple of decades I used a 35mm SLR and a compact rangefinder camera. Why did I then - and why do I now - accept the limitations of a small camera? The answer is simple: convenience, and because usually what it produces is good enough.

Take the LX3 that I use. It has what many see as a woefully short zoom (24mm-60mm in 35mm terms), but that's a range that covers about 80% of my photography. Moreover, the limitation is actually liberating, and interestingly I find myself using 24mm much of the time and ignoring the rest of the zoom. Additionally, with most of my shots I'm aiming to maximise the depth of field, so for me the "disadvantage" of the small sensor becomes an advantage. The maximum aperture of the LX3 is f2. In the days of SLRs that wasn't anything special, with 50mm f1.8 lenses being two a penny, and f1.4 and f1.2 being not too uncommon. Today though, f2 is wider than probably 90% of DSLR lenses. Then there's the image quality, noise, etc. The LX3 output isn't as good as a DSLR: that much is obvious if you view images on screen at 100%. However, that's not the way I look at photographs. At the usual screen size I see no difference, and in prints up to A3+ I struggle to see a difference, so the output, for my purposes, is clearly good enough. Where the LX3 really scores is in its pocketability - it can go everywhere I go with no inconvenience. But there's also the quality of the straight out-of-the-camera JPEGs and the very effective iA (Intelligent Auto) mode. Because it's an enthusiast's compact the user control and the ability to customise the set up are at the level of many DSLRs. All told its a good little camera that is, yes, good enough. Having said that, I couldn't see myself with a wide-angle compact such as this as my only camera: but as camera that is complementary to the DSLR it works well.

Today's shot exemplifies some of its virtues. I set the dial to Intelligent Auto, overrode it only to the extent of dialling in -0.66EV to control the highlights, and, in a church on a dark January day, ended up with this sharp, hand-held image. The background is sufficiently out of focus to emphasise the chandelier above me, but the roof timbers and wooden angels staring down are still discernible, largely because it opened up the lens to the maximum of f2. When I compared this shot to the version I took using Aperture Priority mode it was certainly no worse.
