4 Steps To Blend Photo in GIMP

Published on:


When I was new to the gimp, gimp seems to me as unusable software, that’s not because the software was faulty, it’s because there are not good enough tutorials on the internet that can give me satisfying results.
Gimp is a complex software, and we need to understand that it’s free software and developed by a few developers.

Blending image is a very crucial part of manipulating photos, and we will cover this topic in 4 steps, here are 4 Steps To Blend Photo in GIMP.

4 Steps To Blend Photo in GIMP

Match luminosity

Matching luminosity is important if you are replacing background or matching multiple photos, it can make an image look much more realistic.

Always create duplicate of original layer before applying any effects.


Step 1. Create a check layer by creating a gray layer and set image mode to HSL Color or Lch color.

Step 2. Use a level or curve to match the luminosity. (I will recommend levels because it’s easier than a curve, but the curve is much more powerful)

Step 3. Hide check layer and check your result.

Match Color

Matching color is the 2nd most important process in blending images because it matches the environment of the image.


Step 1. Create or use the same gray layer but set the image blend mode to Luminance (It can help you to match color)

Color balance

Step 2. Use Color balance to match the color. (You can switch between highlights, midtones, and shadows to match more effectively)

Step 3. Hide Check layer and check your results

Match saturation

Matching saturation is not gonna apply to every image, but if you think your image has high saturation or it’s looking unrealistic after doing all those steps then matching saturation can help.

Step 1. Use saturation to increase or decrease saturation in your image.

Match source light

The matching light source is also not gonna apply to every image, but it can make your image more realistic.

There are many ways to match light source, but doge and burn are the best ones.

Step 1. Create a group and put the subject in it.

Step 2. Create a gray layer and set the image blend mode to overlay or soft light.


Step 3. Use dodge and burn tools to the bright and dark image.

Additional Trick

Step 1. Use focus blur to give depth.

Final result.
