Cutting out a subject and putting it somewhere else
Take a figure out of one photograph. Put it into a landscape from another. That single operation — cut out, drop in, blend — produces a large share of the covers in any bookstore, and it is also the thing an amateur cover gets wrong most visibly.
The failure is rarely the cutout itself. Software is good at cutouts now. The failure is that the two images were never in the same world, and a reader can see that in under a second without being able to say why.
What compositing actually is
You are not pasting a shape onto a background. You are claiming that light behaved the same way on both pieces of your image, and every mismatch is evidence against you.
That is why the fix for most compositing problems happens before any editing: choose source images that already agree. Similar light, similar time of day, similar lens. Five minutes of picking the right pair saves an hour of work that still looks wrong.
The tells, in the order readers notice them
Edges. A cutout with a hard, perfectly clean outline reads as a sticker. Real subjects have slightly soft edges, and some of the background bleeds into them. Hair, fur and foliage are where automatic tools give up entirely — they produce either a helmet with a smooth outline or a fringe of the original background color still clinging to the strands.
Lighting direction. A subject lit from the left, dropped into a scene lit from the right, is wrong in a way people feel and cannot name. Check where the highlights are on your subject and where the shadows fall in the scene. If they disagree, no amount of blending will rescue it.
Color temperature. A subject shot under cool overcast daylight placed in a warm sunset scene stays visibly cooler than everything around it. This one is fixable, and it is the most common single reason a composite looks pasted.
Scale and perspective. The camera that took the background was at some height, which puts the horizon line at some point on a standing figure. Get it wrong and your subject is either floating above the ground plane or standing waist-deep in it. A figure whose feet are at the wrong place relative to the horizon is the classic giveaway.
Missing contact. A figure with no shadow floats. Even a soft dark smudge where the subject meets the ground anchors it, and its absence is what makes an otherwise careful composite look like a cardboard cutout on a stage.
The fixes an amateur can actually apply
Pick agreeing sources first. It is worth repeating because it does more than everything else combined. Sort your candidates by lighting direction before you sort them by how much you like the subject.
Feather the edge very slightly. A pixel or two of softness, not more. Enough to stop the outline reading as a cut line, not enough to smear the subject.
Add a contact shadow. A soft, low-opacity dark shape under the subject, falling in the direction the scene's own shadows fall. It does not have to be accurate. It has to exist.
Unify everything at the end. One adjustment over the whole finished image — a color grade, a light grain, a subtle vignette — puts both pieces through the same process and pulls them together. This is why so many covers have a strong color wash over them. It is not only style.
In the Cover Maker. Drop your finished composite in and it reports the real DPI at your trim size, flags art under 200 DPI, and checks the cover at thumbnail size — while the title and author stay live vector text over the top, never flattened into the image.

Silhouettes are the reliable shortcut
If the composite is not coming together, make the subject a silhouette.
A solid black or single-color figure against a sky, a doorway, a horizon, has no edge problem to solve because the edge is the design. It has no lighting mismatch because it carries no lighting of its own. It has no color temperature to correct. And it reads at thumbnail size better than a detailed figure does, because it is a shape rather than a picture.
This is not a fallback for people who cannot composite. It is a legitimate and much-used cover idiom, particularly in thriller, literary fiction and speculative work. The cost is that a silhouette is anonymous, so it works when the figure is a role rather than a person — see Faces and people on covers.
Resolution, twice over
A composite has two resolution problems rather than one. The background has to be big enough to fill the whole panel, and the subject has to be big enough at the size you are scaling it to, which is often larger than it was in its own photograph.
Enlarging a cut-out figure past its native size is where a composite goes soft while the background stays sharp — and that mismatch is itself a tell. Resolution: why a good-looking image prints badly has the arithmetic.
Check the license on both images
A composite uses at least two source images, and both of them have terms.
The two things to confirm are that the license permits modification — some licenses allow use but not alteration, and cutting a subject out is very much alteration — and that it permits commercial use, which selling a book is. Check the terms on each image before you build anything with it, not after. Model and property releases are a separate matter again where a recognizable person or a private building is involved.
Stock images: what the license actually lets you do covers the terms in detail, and Public domain art on a cover covers the case where one source has no license at all.
Make your cover
The Cover Maker is free to use: name your book, bring your artwork, and it draws the full wrap — front, spine and back — to your printer's own measurements. You only pay when you want the files without the preview watermark.
