everyone needs this but where is it panorama match colours ?

[Merlin3]

Hi,

I have 4 photos forming a panorama first two have same colour balance, light levels a bit dull,  but then the next two are notably different , duller still with a notable purple hue or tint ?

scans from 35mm negs. all taken within minutes if not seconds of each other. , swinging round into the light more.

so I could take hours fiddling with sliders trying to match all four up, or can clever photoshop do this whilst knitting them together?

I was hoping 30 yrs of evolution saw to it that such often needed tasks are solved and it knows photos in a panorama have to match.

Has it ?

Hi. Auto Blend Panorama is a great feature, and you can find instruction on this thread: https://community.adobe.com/t5/photoshop-ecosystem-discussions/automatically-match-color-for-panoram...

But since we don't have actual visibility of your images, we do have ways to make images match tonally, more closely. The Match Color command is really helpful for this (https://www.photoup.net/learn/how-to-match-a-color-in-photoshop)

And, it can be done even more manually, with the information in this article: https://digital-photography-school.com/how-to-match-exposures-when-stitching-panoramas-in-photoshop/

Hope that helps!

Hi,

method 1 made a pigs ear of things, nothing lined up, colours remained same.

method 2

https://www.photoup.net/learn/how-to-match-a-color-in-photoshop

how can one judge if the sliders are matching the target image when the target image is a 1inch square on the screen ? Impossible to do at that size. yet that article shows such.

Is there no way sampling the same area of colour in both images can be used to say match that to that and have the brains of Photoshop do it ? trying to fiddle around by eye is somewhat primitive.

Method 3 is about evening up differences in darkness.

My photos have differences in colour, scans from negs, a 4 set panorama across an airfield of grass, taken seconds apart starting off at the evening sky and panning left from it. first is a bit yellowy, the next seems to have gone a bit violet, then the last two are about same and a tad bluey for the grass. The grass thoughout needs to match.

Such colour variations can get in during the scan of the neg.

I just wish one could set the pipette size to 51x51 or 100 x 100 and click the grass in each shot and have it all marry up colour balance wise.

In Raw 17 there is not even an indication of the pipette size for when using the neutral colour pipette. I wish the colour sampler pipette had an indication of size, move it a fraction and the RGB values change. I have been trying to adjust tint to get the one picture match the rgb of the grass in another. but just getting the sample to give the RGB values of the target photo is not easy, it needs to be of an average sample like the pipette in photoshop provides. even that is dodgy as its not 51x51 of the image but of the 'monitor' so if you ar zoomed out it can pick up on adjacent colours !
