Having looked around, it became immediately apparent that finding a ‘natural’ image for blue would be difficult. Weather being what it was, I couldn’t rely on the sky to provide this. My initial thinking was an evening sky might be an appropriately ‘pure’ blue, as the sky in daylight was too bright, as shown here:
So, I continued to hunt for the other colours, thinking I’d come back to blue. Eventually I found a man-made option as I was heading back inside.
The closest match to the colour circle here was an under-exposed shot of the sign. Take on ISO100, 1/250s and f/6.3 (manual). The ‘pure’ blue is a fairly dark colour, so the bright sign wasn’t a good match without under-exposing it.
These are the correctly exposed (f/5) and slightly over-exposed (f/4) versions of the shot and the blue is too light in each of these to really match the blue in the colour circle.
I’ll post the third painters primary – Yellow – on Thursday, before going on to the secondary colours later.
This exercise involves taking two shots of the same subject filling the frame – one with a telephoto (zoom) lens and one with a wide-angle lens. The objective is to look at how perspective is altered by taking different viewpoints with each lens.
The subject I chose was a bridge over Rochdale canal.
The first photo, using the telephoto:
The second photo, using the wide-angle:
Straight away there is an alteration in perspective because of a rather obvious limitation in getting the bridge to fill the frame; I wasn’t on a boat so I had to approach on the tow path.
Comparing the shots, the first does give a sense of distance from the bridge while the second does feel notably closer. Comparing items within the scene however, the lock gates feel much closer to the entrance to the bridge than in the second – where they are very much a distant element of the scene. Essentially the first shot feels much ‘flatter’ while the second has much more depth and the canal present lines of interest.
