When is our images over saturated ?

13 Aug 2021 8:35AM   Views : 524 Unique : 327

Ever wondered if the colours are a little to strong or one colour is ?
How can we check this and even fix it.

Here is a classic pin up which by there very nature were always over saturated but will demo what we can do.
1. Open image.
2. Open an "Invert" adjustment layer. Change the blend to "Color" and the opacity to "50%".
3. This should now be black and white. If you see any colours they are over saturated.

The Fix...
4. Go below the "Invert" layer and open a "Hue/Saturation" adjustment layer.
5. In the panel click (or double click) on the finger with arrows on either side.
This will change the cursor to an eye dropper.
6. Move ove the image and click on any colour you see.
7. Now move the saturtion slider down until it just takes away the colour.
Repeat for any other colours.
8 Turn off the "Invert" layer to see results.

This is very quick and will help you to control those colours.
The opacity slider on the Hue/Saturation layer can always be decreased if you want to push that saturation.

These are quick tips to try help people understand PS as it can be a bit overpowering at times...

This is really useful - thank you Robert. I don't use PS but I'm sure your guide will be just as effective with other software.
Thanks again.

That's a useful and interesting tip Robert.
When colours are oversaturated the fine detail gets lost so bringing saturation down does help there.

That's an interesting and clever technique, and no doubt some will find it very useful, though personally I'd rather just trust my eyes and my judgement.

Been thinking about this a bit more, Robert. You say " If you see any colours they are over saturated." But I have a few questions:
By what authority is such a judgement made? Who, or what, is the arbiter here? How is the datum defined? And crucially, how did you arrive at precisely 50% opacity for the 'invert' layer ?

I tried a few images this afternoon, using my standard jpeg settings. The sooc results, from the point of view of colour saturation, looked very close to reality ( which was the intention ), but subsequently using your technique, and following your instructions to the letter, I was required to desaturate some colours, and the result in each case, I have to say, did not compare well with my memory of "reality," very definitely appearing comparatively undersaturated.

( I view images on a MacBook Pro 'Retina' screen, with the display set to sRGB, and all 16 levels of the Epz 'calibration guide' clearly defined. My browser is Firefox, adjusted for 'advanced' colour management... i.e, not just for images tagged with ICC profile)

Hopefully you can give me some clarity.

Hi Alan
This was a tip I have picked up and like any adjustment that you make it is down to what you as an individual want from an image. No one adjustment will fit all.
I did state that you can use the opacity slider to fine tune the level you want.

I have to say Alan that I find the tone of your post rather aggressive, not for the first time.
I am happy to discuss anything with anyone when conducted in the correct manner.

For that reason I think it best to stop this here...

Hi Robert
I apologize if the directness of my approach to enquiry offends your sensibilities I can assure you that no such offence was intended.

But if you are therefore disinclined to discuss the subject further, that's fine by me it no longer seems necessary, as your response has more or less confirmed what I was thinking anyway.

Regards
Alan

I will deal with as it not that hard.
First the inverted layer: - The blend is set to colour as that is all we are dealing with. The opacity is set to 50% as there are two layers , the image and the inverted layer which is equal and opposite in the colour wheel. For the Image layer to seen through the inverted equally the opacity of the inverted layer needs to be 50%.
By what authority is such a judgement made?
This is really easy: - That judgement is yours and yours alone. It's your picture and you set what ever level of saturation you want.

"reality," very definitely appearing comparatively undersaturated.
The adjustment will set the colour at a mid point which will be a more muted colour as the pin up image showed. This is where we either increase or decrease the level of that colour. Does this make saturated colours wrong, no of course not as life and nature is full of saturated colour on birds, flower or even red lipstick. Our brains get use to these colours as the normal but they are still saturated.

The whole idea of this was to give an easy way to see which colours are saturated and as the adjustment is made you can turn the muted layer off to see how much you want to adjust each colour. Once again I use the word "you" as it's your picture...

"I apologize if the directness of my approach to enquiry offends your sensibilities."
The use of the word directness is just another way of being rude. As a inner London council house kid I can assure you that you could never offend me but that doesn't give you the right to take an aggressive or as you put it a directness with anyone.

To everyone else I am very sorry that this post has turned out this way but some times people have to be called out.
