How can I make a composite from two different cameras look more natural?

I’m compositing a person from one photo into a wedding photo shot on a different camera. The source images differ in sharpness, color, and overall quality, and the result looks obvious even after scaling, rotating, adjusting levels/color, and doing some dodging and burning. What can I do to make the two images match more closely and make the composite less noticeable?

Three things that are likely making the composite not look right: differences in sharpness, color and lighting direction

  • Lower quality of the image of your wife taken with the Coolpix - only real solution here would be to lower the quality of the main image to match. For a start, try adding a bit of blur to the main image, and once you've added your wife in, resharpen the entire image together.

  • Lighting. This is probably the most important. The lighting in the two images must match as closely as possible. If the light is from the right and behind in the main image, then it needs to be the same in the image of your wife. If it's from the opposite side you could try to flip horizontally.

  • Color. If the main image was taken outdoors, and your wife indoors (or the lighting is different in color) then you'll need to adjust white balance or color correct in some way.

Your best bet is probably to retake an image of your wife with a higher resolution camera, in the same light as the main shot.

The camera difference itself matters less than matching the images in three areas: lighting, color, and sharpness.

  • Lighting is most important. The inserted person needs to be lit from the same direction and with similar intensity/contrast as the wedding photo. If the light is coming from the opposite side, a horizontal flip may help.
  • Match color and white balance. Different cameras and lighting can shift color. Adjust overall color so skin tones and scene lighting feel consistent.
  • Match sharpness/detail. If the cutout image is lower quality, it may never fully match a sharper DSLR image. A practical trick is to slightly blur the main image, composite the subject, then apply final sharpening to the whole image together so both parts share a similar look.

In many cases, it’s easier to degrade the better image slightly than to make the lower-quality image look better. If the lighting direction or scene lighting is very different (for example indoor vs outdoor), the composite may still look unnatural no matter how much editing you do.
