Technical controls P3 (b)

This image is one of the first I took on this shoot, my aim to frame the picture correctly allowing all object on view, and framing the leaves as though they were on the ground, rather than sitting on a table. I did not take into great consideration the shutter speed, aperture or ISO for this shot, hence resulting in an over exposed image. I had my aperture at f/32,  meaning the image was very light and over exposed.

2nd Picture

The factors of this image were more complex than my first, I took into consideration my shutter speed, ISO and aperture. Lowering my aperture to f/11, meant less light was let in when the image was taken, resulting in a darker image. I planned to shoot a sharp image when taking in all factors. I had the ISO at 6400 as the studio was very dark, fortunately I did not get much grain on the image, however I believe having such a high ISO left me with a painterly image as light sensitivity was high, which is what I hoped for. It is sharp yet slightly grainy, similar to a painting in some aspects.

3rd Picture

This image was during a trial and error stage, I was changing the aperture value to see how I could achieve the sharpest and better exposed image. Unfortunately the image turned out over exposed. Too much light hit the sensor for this shutter speed, meaning the result was an over exposed, light image. 

4th Picture

I used another groups set for this image, allowing me to see how the light in their set was different in comparison to mine. I ended changing my aperture to f/25, allowing more light to hit the sensor within the 1/64 shutter speed. The ISO was left at 6400, meaning light sensitivity was still high, as the studio was still very dark overall, only lit by certain studio lights. This resulted in a slightly grainy picture, however again it adds to the painterly affect I hoped to achieve.

5th Picture

For me, this image has a very good contrast with dark and light, the pumpkin is very bright and powerful in the image, with the aubergine in the middle third and then the block of wood in the right third, which is much darker, but very sharp which contrasts the brightness of the pumpkin. This image follows the rule of thirds, every third has a large item and the subject (watch) is offset to the right third. For this image I kept my shutter speed at 1/64 but raised the aperture to f/32, meaning a good amount of light was let in creating a well exposed image.

White Balance

The process of setting white balance is very simple to achieve. Firstly, I took a properly exposed indoor image of blank, white paper. Then on the Canon 7D I navigated to the 'custom white balance' option, and pressed set, subsequently I selected the white image, assuring it had been exposed well enough to give me the correct white balance for the room, following this I clicked 'set' again and then changed by cameras white balance settings to 'custom white balance' allowing me to shoot in the white balance I just created. I repeated this process when moving to an outside location for different images. 

This image was taken with my 'custom white balance', the approximate colour temperature is 2000-10,000.  The image is very similar to the actual scene, meaning the custom white balance works well, showing a neutral colour that suits the image.

This picture was taken with the white balance set to 'Tungsten light'. This created much lighter image, causing the colour temperature to fall to roughly 3200, therefore meaning the image looks colder and less natural compared to the actual scene.

 As I moved outside I had to reset my custom white balance to achieve a more effective image. If I had not adjusted it, my images would come out under exposed as lighting is much brighter outside. The custom white balance allowed me to take a well exposed, sharp image.As the white balance was correctly set, and aperture priority was on, this allowed me to keep ISO low, so light sensitivity was low, resulting in a sharper image.

 This image came out well exposed with my custom white balance. I kept a low ISO of 100, to prevent the image from having noise or grain. My aperture was set at f/1.8, and my shutter speed at 1/1600 meaning it was fast assuring I captured the flag at the correct time with no blur.

This image is one of my favourites from the shoot, although it is not a striking photograph, the overall composition I feel works well. Having set my custom aperture, the colours of the image are shown similar to real life. The ISO again was set at 100, with a f/1.8 aperture and shutter speed of 1/1600, it resulted again in a sharp image with warm/neutral colours.
