Resolution- The detail of which an image hold, the term applies to digital and film images and it can be measured in a variety of different ways. In terms of images the higher the resolution is in an image means the more detail that an image will have.
Who’s Uses Resolution and Why?
Resolution is mainly used by photographers and image editors in order to make their image quality better. If you have an image with a really low resolution then it won’t have much detail and it will also look quite blurry. It is important for a photographer to have a high resolution in their images as it means that they will be able to show all the detail that they can possibly show and it also makes their images look very sharp. There is a very big difference between images with a low resolution and a high resolution and I think that the quality of an image really shows in terms of how professional you are as a a photographer and also it shows how seriously you take your work and whether you really want them to look good or not. I have included an example of the difference between a low resolution image and a high resolution image.
As you can see from the high resolution image the image is really sharp and you can clearly see all of the detail. Where as in the low resolution image you can’t really see much detail and all around the outside of the hand and the lamp it looks quite pixelated and blurred.
How Is It Useful?
Resolution is useful in photography as it makes your images look a lot more sharp and it refines the details in the images. It allows you to see a lot more detail and it can also make an image look a lot more professional. There are many different ways that you can change the resolution of an image including using preview of images on a mac and also using photoshop. Using photoshop means that you have more control of the resolution and you can change it to whatever level you want meaning you could have a really high resolution a mid range resolution or a really low resolution. This also shows how it is relevant in photography as this type of resolution is to do with images and pictures and there quality.
Whilst focusing on resolution we were required to do a task involving resolution and taking our own images in order to back up our research and to show that we understood resolution. To do this we took a cut out of a sudoko from a newspaper and stuck it to the wall and using our cameras we shot the cut out nine times. Each time we were constantly changing the aperture and the focal length. We used nine different shots one for each different image;
I have included the contact sheet of my final nine resolution shoot images.
This was the first task that we completed for resolution we then had to use these images and zoom and crop on photo shop to be able to clearly see what resolution was the best and the worst for each focal length.
To do this task we loaded 3 images from each focal length all with a different F stop into photoshop and loaded the navigator. After doing this we then zoomed the image up to 100% on the navigator so that we could identify if the image was still clear and whether there was any colour fringing around the lines and also the words and numbers. We then cropped the images so we just had the left hand corner in the frame rather than the whole thing, this was so that we could focus on just the lines and the corners of the puzzle. We then repeated this two more times so we could test it with each focal length. There were a variety of different results which all depended on the focal length and the F stop. After zooming in and cropping around the left hand corner, we repeated the same process but this time we cropped the middle of the puzzle so that you can focus more on the numbers and the thinner lines in the centre rather than the thicker black lines around the edge this is also showed a variety of results depending on the F stop and focal lengths. We then saved these images and created three different contact sheets for each different focal length each of which containing the first images that we took from the original contact sheets, the zoomed in pictures for the left hand corner and then the zoomed in pictures from the centre of the image. There is a total of 9 images on each contact sheet 3 for each F stop that we focused on. I have included the three different contact sheets below with an analysis into the results and which image I thought had the best and which one had the worst resolution.
I am very happy with the way that my images came out and I am very happy with the final results.
I think that this task was good to do as because in our triptych project our images are being blown up quite big and displayed in a place were a lot of people can see it, it is important that we are able to get the resolution right so that the image looks good and that the quality is good enough for it to be blown up quite big. I think that if they were blown up quite big and the resolution wasn’t right then my image wouldn’t look as good as I first expected it to and I won’t be very happy with my results. I think that knowing the resolutions now and knowing what F stops I should use a different focal lengths will give me the ability to get good high resolution images in my final project rather than taking one image and it being wrong and of a low resolution and having to take it over and over again until I get it right. I will use my knowledge of resolution and F stops whenever I take my images or change my focal length.
