For example, 20 different images of the same thing, or a front and a reverse photo of 10 things, or a single photo of each 20 different things would all be classed as 20 images, so the cost would be $50 setup plus 20 x $16 = $370.

Similarly, an individual photo of each of 40 things, and then a further 5 "group shots" of each of the model ranges would be 45 photos in total and would cost $75 setup plus 45 x $15 = $750.
