Objective and Scientific Photography

Photography as well as being an art form it can also be used in a scientific and objective way for example it can be used in forensic science and could be used in other professions such as police work and images could be needed by doctors. for my piece of objective photography I was going to do some photography with an infrared filter but the place I bought it from messed up my order so instead I chose a simpler thing, I chose to photograph a flower over ten days to see how it would change.

Photographic Practices - My Final Images

The subject I chose to focus on for the final images of my Photographic Practices project was wildlife and nature, while photographing my chosen subject I decided to try and capture a lot of different things within the subject.

Street Phototgraphy

When I first started street photography I felt very nervous and my confidence were very low, I think this was due to me think about what reactions I could get and if they'd be negative towards me taking photos, especially when it contained them. throughout my experience the longer I did it the more confident I felt and felt like a was more able to take certain shots, whereas a lot of photographers stay in one place and wait for the right moment I decided to walk around and try to capture the right image, like most street photographs I decided to shoot in black and white I felt this created a more atmospheric effect and captured more detail. 

Raw Workflow

Raw Workflow 

Taking photos in Raw is a way of saving a photo with the minimum amount of data, this type of file can be capture on a digital camera, motion image scanner or an image scanner, the image is taken with the camera, the information is taken in through the sensor and saved immediately, it isn’t white balanced, saturated sharpened, ect., it is called a raw file because there hasn't been any processing done to the image or film yet and is not yet in a position to be printed off. Once the file is open it is then possible to edit and change the images information to suit what the photographer or filmer wants. This type of file has many positives and negatives.

Positives

-You have more control over your image
raw files let you change almost anything when it comes to processing your image, for example you could have taken a image and it appears to exposed you can open the raw editor and change the exposure to whatever you want, another example of being in control is you could have taken an image which hasn’t captured the colours correctly so you can show certain colours more and even change certain colours to what you want.

-You can change a lot of little things individually

You are able to change things like contrast, highlights, shadows, clarity, vibrancy and saturation, even though you can change things like this on a normal image file raw gives you more of a natural effects, noticeable effects and allows you to change a lot of things separately.

-Raw images have a better quality than other files such a JPEG 

You get a better quality because the sensor on the camera is able to detect a lot more date than other forms of file.

Negatives

-It takes a lot of time to correct and change images

it takes a lot more time to change and edit a raw file because it is all done individually and a lot of things have to be changed rather than just a big change with JPEG for example if some wanted to change the exposure with JPEG they could do it all at once but with a raw file it is better to scan over and change everything individually to get the best outcome

-File sizes are a lot bigger
the size of a raw file is a lot bigger than other files which will cost the photographer more money on memory for the computer, storage devices and memory cards in camera, because the files are a lot bigger if you have a pc which isn’t that good it will take a longer time to open and edit the image.

Guessing Shutter speed, ISO and Aperture

This was the first time we went out to take photos during this assignment, we went out into a surrounded courtyard at around 9:30am while the sun was low so shadows were created, before we went out we set our cameras up to a default setting which was 1/125 shutter speed, F8 aperture and and ISO of 200. the first image was ok at a low level where it was darker but started to become over exposed towards the sky where it was much brighter than the bottom, we tested and changed the camera settings to throughout the images, eventually i picked the right cameras settings, i kept everything else the same but just upped the shutter speed

In this image i did the same thing, guessed then started two change setting around, although in these images instead of changing the shutter speeds and aperture it was easier and more effective for me to change the ISO, but in the later images i wanted to capture the detail on the windows this meant it was easier to change the shutter speeds and aperture to capture the light.

These images were harder to capture because the lighting went from one extreme to another, from the sky the light was very bright and over powering to the camera and behind the wall there was a lot of darkness and shadows which took a lot of detail away from the wall, there was also a third factor and that was the brick wall to the left of the image which was reflecting light.

These images were easier to guess and change the settings because there wasn't a lot of information to deal with it was usually just one area of light and shadow and one area that would have to be changed, for example in the one of the ice arena it was only the sky which was over exposed and needed to be captured in detail.
