The composite set consists of 78 dng files (40mp) and can be used for creating your own composites by mixing the different images. Almost all images are shot with the same light direction, so easy to match with eachother. Compared to many stock sites the images in this set are not jpg's but dng files. This means that you can process them in the way that you want because all the color information is still there and you get much more detail out of a single image.
