E-Book covers are images containing a perspective-based (i.e. looks as if 3D) representation of a book, folder, binder, report or other document. You can get best idea about books creator via https://firewirecreative.com/.
They are very popular with authors, publishers and marketers of E-Books and you will often seem used on web sites, in advertising materials, and in some cases even in the product itself (for example, many E-Book authors like to put a copy of their E-Book cover on the introductory page of their E-Book).
E-Book cover graphics are most frequently prepared as PNG or JPEG files, as this generally allows the highest quality images to be displayed – as both formats allow 24 bit color (allowing over 16 million shades of colorto appear in a single image). A really good E-Book cover design can look truly beautiful, and the best ones could almost (but not quite)be mistaken for a photograph.
There are at least four different ways that these graphics can be prepared. These are:
1. You can try and draw the image by hand in an ordinary painting or graphics program (e.g. the Paint accessory that comes with Windows, Corel Paint Shop Pro, Adobe Photoshop, etc.
The trouble with this approach, is that it can be very difficult to add text or graphics in a way that matches the perspective of the background (the same skew, the same orientation and the same shrinking with distance) – and if you don't match the perspective of the background it will completely ruin the effect. To avoid this problem, some backgrounds/templates have the covers in a "flat" orientation so you can just add your own text on horizontally – unfortunately these kind of backgrounds/templates often don't really 3D at all.
