Exposure triangle

When taking a picture there are a few things that can affect the image one of them is the triangle of exposure. 3 things affect the exposure, Iso, Aperture (f-stop) and shutter speed. These 3 settings can be changed to alter the exposure whilst taking a picture.

This is a normal image of the phone with all the exposure aspects perfect for the conditions, its a good colour, you can clearly see what it is, it isn't too dark or too bright. The shutter speed was on 1/100, so it wasn't open for long, the Fstop (aperture) was 5.0 and the ISO was 800

I then altered the ISO on each image but I kept the Fstop at 5.6 for each image and the shutter speed at 1/60. I set them at this because I took a picture on automatic mode to see what settings I would need so you could tell the difference between the Images
 100 ISO



 200 ISO

400ISO

800ISO

1600 ISO

As you can see the higher the ISO the more exposed the image becomes. It starts off quite dark on 100 ISO then on 1600 it looks over exposed/ too bright.

I then set up the Fstop at 5.6 and kept the ISO at 400, the one I changed this time was the shutter speed.
 1/10
 1/20
 1/40
 1/60
 1/80
 1/100
 1/160
 1/200
 1/250
 1/320
 1/400
 1/500
 1/640
 1/800
 1/1000
 1/1250

 As you can see the shorter the time the shutter is open the darker the image becomes. This is because the shutter is open for less time so less light can get through the lens, the longer it is open the more light goes into the lens so it becomes more exposed where ass the shorter time its open the less exposed it becomes.


After doing the ISO then the shutter speed I have now done the aperture (f-stop) I kept the shutter speed on 1/60 and the ISO on 400 for all these Images
 4.0
 5.0
 6.3
 8.0
 9.0
 11
 14
 16

 20

25

As you can see the higher the F-stop the darker the image becomes, so when it is quite a bright day its better to keep the F-stop quite high but if its a dark day, if you were indoors or it was overcast you should keep the F-stop low but not too low that it becomes over exposed 

So overall these 3 settings affect the exposure when taking a picture, so it can be a lot to mess with when taking a picture but if you get them right then your photograph will look very crisp and clear.

Lines in Photography

On our third day of taking pictures we got asked to take pictures of different lines that were vertical, horizontal and diagonal, pictures with lines within them make your eyes follow them across the image rather than on one point. We got given half an hour to get as many pictures as we could of different lines, so I went down to Hyde Park to take these.
These are lines on a fence we walked past to get to Hyde Park, these were the first lines we walked past, we thought they looked cool because they have water droplets on them so we took pictures of them. These are horizontal lines.
This mosaic has lots of lines on it so I chose this because it has such a range of lines within the picture, but because there are that many lines your eyes don't follow one specific line but the picture looks good because there is that much variety.


This is a vertical line in Hyde Park, because of the positioning of the picture and the angle of it, your eyes are drawn up the picture towards the top because the lines make your eyes follow where they are going, I used the macro setting for this so I could get the top in focus and the bottom out of focus.
Finally diagonal lines are good pictures as long as the camera is tilted, it gives the picture a different angle. As you can see I havent tilted the camera when taking the picture. I also took this picture on Macro mode but I should of upped the f-stop so more of the wood was in focus rather than just the middle of the plank, then the picture would look better.

Overall lines in photography are good because you look at the whole picture rather than just one focus because your eyes follow the lines, up, down, across and from corner to corner, depending on the lines in the photograph.

Autumn photographs

Autumn Photographs

Today we went down to a local woodland area where we went to get some pictures of the woodland changing because of the Autumn leaves coming through.

 I started walking through a woodland area and this was one of the first trees that I saw with orange leaves so I thought it would be good to take a picture because it had a nice Autumn look to it. I took it on manual and because it was quite dark I put the ISO up to 800 and it gave the picture a nice bright, clear picture.
 This picture was slightly out of focus so I edited it to make it look darker to give it more of a scary look but then I messed with the colours of the leaves and made them orange so it had more of a Autumnal look to it. I took the picture on ISO 1600, Fstop 5.6 and 1/60 shutter speed so at first it was quite bright but because the shutter speed was so slow and I was taking the picture hand held it was a little blurry.
I then found a conker in the middle of some leaves but to make the conker stand out more I put the picture into black and white in photoshop. I made another layer of just the conker then put it over the top of the black and white image so the conker still has its colour therefore will stand out. I took a picture of a conker because they only fall out of trees in Autumn so they are a very Autumnal thing.

Architecture

Our task for today was to go out and take pictures of new and old architecture, we started off at a church near college, then went down hyde and found a modern building which was the bus station.

 This was the first picture I took of the church I thought I would get the sun in the corner and an upward shot of it so you can see what it look likes from the front. The sun also gives it a good effect of a lens flare.
Then I wanted a different shot of the church that not many people would see so I went round the side to get a new angle of the church, in this shot I have the main building in the middle, another building closest and an extension on the left, this just shows the church from a different view.
This is the modern building I chose, it is the bus station, it is one of the most modern looking building within hyde so i thought it would suit the new architecture category. This is the side view of the whole station on a side that isnt viewed by a lot 
This is another angle of the modern building I chose in Hyde, this is from the front of the building so you can see what the entrance is like and the roof is very modern, you wouldn't see a building like this 100 years ago, it is a very modern building.

These pictures show how architecture change over years, the bus station is clearly much more modern than the church and it will always be evolving and changing as we get more advanced.
