Merge the Images Challenge/Play
Apr 23, 2012

I have often been troubled trying to merge two images of different lighting and hues/mood. Especially if one was taken at a different time of the day or different weather conditions.

Just as an example, I picked (almost at random) two such images both taken in Italy. I extracted (very roughly) the two girls in the one and changed the b/g to uniform green to make it easy for you to take the girls and put them anywhere in the other image. You may need to rescale. The emphasis is on getting the girls to blend naturally in the b/g. Don't worry about composition, small details etc, as long as you produce a 'believable' blend. And tell us how you did it...

Feel free to use images of your own as long as they have noticeable differences in brightness and tonality.
Thanks for playing

Hi

Not sure it is possible......

Easy to drop in the image but one (the girls) has strong sunlight...the other more dull.

Shadows on girls and direction of sun not the same as in buildings.

Shadows on/under vehicles not consistent with the light on the girls......

You would need a new sky to reflect the sun on the girls and then amend the shadows under/around cars etc to match...

Just my thoughts...

Best wishes

Ray

Like Ray said, you'll never get a completely believable blending of these two images.

Here is my try anyway. I used two layers. One Levels and one Hue/Sat. I player with the sliders until I thought it looked somewhat decent.

Realistic mikes. Well done.
In reply to Sunshine_boy, Apr 23, 2012

Maybe a little less shadow under the cars on picture right to match the direction of the lighting on the subjects? IMHO that is ..

Hi Ray,

You are absolutely right. I deliberately picked two images with a lot of contrast between them just to see what issues arise and what/how retouchers face these issues. From what I have seen posted so far, I note:

  • Choose the right position of the placing

  • Resize placement to fit background perspective

  • Need to decide which image to adjust to the other or make them meet halfway...

  • Use Levels/Curves or Hue/Sat to make adjustments

  • Deal with the Shadow problem and/or create convincing new shadows

Something I have not seen used (yet) is the 'Match Color' which I think is useful and effective (or no good at all). I always test it to see its results.

Yes, it's a tough one!...
Let's see what other ideas/methods are brought to the table

Thanks. I know the shadows aren't perfect, but I am confronted with this problem everyday at work, usually not to this degree though. So spending more than a few minutes just isn't feasible.

What I do know is this. We know the pics are fake, but if it was shown to someone who never saw the originals, and to see/hear their reaction to the photos, will give us an indication of the realistic quality.

The trick I have learned is to match contrast more so than color. And to increase saturation on the brighter parts of the photo only.

My Impression......

Impressionistic painting that is, although not totally impressionistic.

I am surprised not more forum members participated in this exercise!

Hi Mike,

It is a good exercise/practice for a very common problem. Maybe too exaggerated but a lot can be learned from it I believe.

Nice take (both your 'entries').
Could you share your technique in getting the girls' shadow like you did?

My try

This was not the best merge as light on merged subjects different from main light.
