I decided against uploading photos for an iPhoto book, because of 1) limited flexibility and 2) uncertainty of the paper quality for a lot of expense. I have used HP premium plus photo paper for this purpose so many times in the past, that I was confident in what the end result would be concerning image quality. Mistaken. Thin paper and very poor color contrast resolution in side by side image comparisons. Perhaps the chemicals in the instant dry paper is the difference that makes the images appear flat. I am careful that my paper and inks are compatible, and I do not skimp on cheap paper, but this paper ranks with the worst. Sorry, and I will be returning it. The thinness would be acceptable if the image quality remained the same. New? not improved. Bring back the other.
