It is a common rule to believe that only 20% of images worth being post-processed, 80% can be discarded or archived. This ratio is arguable and can even be significantly higher but that’s not the point of this article. Therefore, it is very interesting to display images by group of typically 10 images. This way will let the software display large thumbnails and 10 images is OK for a human being to “process”. I mean, the photographer with just a little bit of experience can decide almost instantly from this group of 10 which one is the best. And sometimes, it will be 2 of them, hence the same ratio of 20%. However, most of the screens are now with a ratio of 16:9 and most of the cameras are shooting 3:2. So, showing 10 images is not efficient. It means “too small thumbnails” compare with the size of a 16:9 screen. But if you just reduce this number by a little bit, 8, you come to a good ratio, kind of nice compromise. That’s why there are (almost) always 8 images maximum in Futura Photo after having grouped similar images altogether.
