You can clearly see from this that the best file format is a JPEG. It is the clearest photo and doesn't look pixelated. By changing the photo to a GIF and PNG, the image quality has deteriorated. The ideal way to save the image would be as a JPEG as it does not look much different from the original image.
I have saved the image as a JPEG because it is the best quality. I compressed the image from a quality of 100, 50 and 25. The original image has much brighter colours than the 25 quality image. The image has also become pixelated. The size of the 50 quality image is different. The difference in colour is less noticeable in 100 quality.
I changed the file type to a GIF and changed the colour depth. The difference with the 64 colour depth is that the colours are not as bright and the image looks slightly distorted. When the image has 16 colours the quality is bad. The size of the image is smaller and will therefore take up less memory but the quality is very bad.
www. D2. Well done. A well written and detailed report. You have clearly explained why different file types and compression techniques would be used, and illustrated it appropriately, showing the effect that the compression can have on graphic images.
