They are sometimes referred to as a “digital negative”. This means they are not processed by the camera at all and represent the purest image, as taken. These files take data straight from the camera’s sensor. So, if you were looking to print images above standard sizes, you would need to choose less compression. Just bear in mind that the overall quality will be affected the more compressed the file. The camera will allow you to set the level of compression, so more, or less, photos can be taken. This results in a greater amount of pictures possible when compared to lossless files. Whilst the actual number will vary depending on the camera used, it is possible to take over 1500 images using just one 2GB memory card.īecause this is a lossy file, the images are compressed. This is the most common file format used by amateur photographers, mainly because so many pictures can be recorded on one card. A TIFF file is, in principle, a flexible format that can be lossless or lossy. To reduce file size, the camera can discard part of the data not easily perceptible to the human eye. If all of the data is stored, this is known as a lossless file. When a picture is taken, the camera records the data onto the memory card as a file. For viewing, the file is decoded, and there are three main types of file used: JPEG, TIFF and RAW.īefore we look at these file types, it’s pertinent to explain the difference between “lossy” and “lossless” files. With digital photography, images are stored as a digital file. Then, after development in the darkroom, a negative was produced. In past times, photographs were captured onto light sensitive film. “Half Dome and the Better Half” captured by Thomas Hawk (Click Image to See More From Thomas Hawk)
