Photography Class 6, Manual Setting & Lightmetering
This week we are moving from having our cameras on the Aperture setting to Manual, wooohoo!
Aperture Priority Setting
Up until this point in Aperture Priority Setting we set up the camera/photo we are going to shoot with the following in mind:
- A setting
- Depth Of Field
- Check shutter speed
- Change ISO if a faster shutter speed is required
However on manual setting this is how the flow goes:
- Depth Of Field
- Set the shutter speed
- ISO change only if a faster shutter speed is needed
Looks the same?
The main difference between Aperture and Manual settings in the flow is the consistency in results.
So in Manual Mode we move on to working with our light meter.
This can be found on the screen at the back of your camera, it has a 0 in the middle and a + to the right and – to the left, it looks something like this:
When you adjust your shutter speed it adjust the light metering.
You can easily find the shutter speed as it is denoted by numbers, for instance 1″, the ” denotes seconds, if there is no ” then it is a fraction of a second as in below 1/8th of a second.
I am no good at maths and find trying to work this kind of thing ends up ruining my photography as my instinct and spontaneity dampens, however I suppose it is to get a good basic understanding of these things of course, so below you will see a table of how the shutter speed changes every three clicks.
1/2 second- 3 clicks moves it to 1/4 second and then onwards 1/8 1/15 1/30 1/60 1/125 1/125 1/500 1/1000 so basically it halves the exposure between two f stops.
3 clicks = 1 f stop which halves your exposure time (less light) or doubles, depending which way you are going. One click is a third.
The aperture will also change if you move it on 3 clicks in the following way:
1- 1.4- 2 -2.8- 4- 5.6- 8-11-16- 22-32-45
Every 3 clicks is the same as changing the shutter speed 3 clicks.
If I zoom out, my camera will give me the lowest aperture of 3.5
If I zoom in the lowest is 5.6
You can see this written on your lens as shown below.
Our teacher asked us to go outside and set up our desired Aperture setting after having chosen our target, a skyline, then to set out shutter speed to 0, if this was then too slow we were to adjust our ISO to avoid camera shake also.
You can set your camera up to show a histogram. Some cameras also show you a photographic example of what you are going to take before you actually take it which is really handy, mine does not. You can set your camera however to show you a histogram of your photograph afterwards, this is how mine works. It can show you immediately afterwards bits of your photograph that flash, this is where it counts pixels of specific brightness and means that that particular section is over exposed, you can also look at the graph on the histogram to see where any amendments could be made next time around if you don’t want to rely on just your visual determination when looking at your photograph through the screen afterwards.
Left side is where the darker pixels get recorded
Right side is where the lighter pixels get recorded
Middle section is grey.
Too much at either end shows over or under exposure depending which end it is.
A histogram is a statistical representation of information and looks roughly like this:
Our homework was to shoot in the settings above and play around under and over exposing shooting a landscape. The landscape part was the bit that got the better of me, playing around with the exposure however was the easier bit. After a manic week of work and studies I had no time to go shooting during the week, with a weekend full of exhibitions/work I had very little time there and so after an exhibition on Sunday went out trying to find a landscape. I ended up driving all over the place, as soon as I got to the North Downs it started pelting it down, so I had to rely on a few dry spells, literally minutes at a pub that was frequented for lunch.
However my landscape turned out more to be a wet landscape as in a river, a river landscape?
Can you guess which one above was at the correct exposure without looking at the stats?
You can see in the selection of photos below that I went from slightly over exposed to under and then totally over to a point where it just almost became white. I actually really like the under exposed ones, as they are similar to taking all the colour out except for a key colour which I really like doing in my editing, plus I think it looks more striking. This is for me an example where the histogram in my personal view shouldn’t be rigidly stuck to because it is personal preference on your style, just use it as a guide.
