Trying to eliminate green cast in portrait.

This is a scan from a colour neg. of my partner's eldest daughter. It was a crop from a dinner party image.



As can be seen, there's a greenish colour cast, mainly on the lower face and neck.

I've had a half-hearted go at it, but I'm sure there are those on this forum that can make a much better effort.

I'd be grateful if details of the PP are posted with any adjusted images.

Jim

Re: Trying to eliminate green cast in portrait.

You can get better results from scanning as a colour negative and post processing the results rather than have the scanner convert it to a positive.

The colour temp of the scanner light through the orange film base is the cause of the green tint.

The scanner software surely should have compensated for the orange?

Unfortunately I don't still have access to the neg., so I have to work with what I've got.

Re: Trying to eliminate green cast in portrait.

I had a quick play in faststone

My suggestions
Cloud adjust
Red +5
Green -3
Noise reduce to blur and smooth the skin tones a bit

Regards
Andy

Re: Trying to eliminate green cast in portrait.

If you have Lightroom then in Develop module select Adjustment Brush.

set Tint slider to 100 red
make brush very soft using these settings
size 11
feather 90
flow 20


Then simply paint over green tinted areas you want to change as required. Make multiple brush strokes to make the change stronger.

I have not done anything else to the image.

Unfortunately it's a different base colour for different films and the temp of the light source changes with age, so a "White" setting needs to be made before scanning.

Pity you don't have the neg, as I'm sure you could do better by photographing it.

Re: Trying to eliminate green cast in portrait.

Thanks for the replies - they've given me something to work on.

I didn't take the photograph, but I thought that it had a nice, natural unposed look. I think this is because the photo was of a group, and she didn't feel that her photograph was being taken, and so was more relaxed.

Re: Trying to eliminate green cast in portrait.

I got most of the way there in OV3.

Auto Tone Correction : manual, strength 4
Contrast: +10
Colour Balance: red -13, Green -25, Blue -20
Hue: +1
Saturation: -1

Although I liked the overall feel of the OV3 edited photo there was still a slight green/yellow tinge remaining in the neck area that was too intrusive. From here I took two different routes.

Carrying on in OV3 I adjusted the tone curve for the seperate colour channels. I placed an anchor for the green channel at the midpoint on the diagonal line and brought the top endpoint down 15% to form a smooth curve. For the red I also anchored it at the midpoint but brought the top down by 10% in a straight line.


From an original by Jim Ford

I also tried bringing the red down in a slight banana shaped curve of no more than 5% concentrated at the top end which gave much the same effect as adding the RED filter. I liked the overall warm feel of this as it gave her hair a nice lustre and gave her neck the best treatment but this might be too much of a departure from the original for some.


From an original by Jim Ford

As I could not find a completely satisfactory way in OV3 of reducing the yellow component (there being no "yellow" tone curve or slider and I could not find the right mix of reducing the red+green) for my second route I popped into Elements 12 and added a Hue/Saturation Layer to the picture from my first set of OV3 changes...

Master: Hue +9, Saturation -12
Yellow: Hue 0, Saturation -72
Green: Hue 0, Saturation -100

This gave a better reduction in the green and yellow cast but the overall effect is a little harsher as though it had been lit by a too strong flash. On the plus side it is closer to the original.


From an original by Jim Ford

I did try doing everything in Elements but much preferred the result from using OV3 first.

It was particularly interesting that you used - and preferred - Olympus Viewer 3.

I have OV3, but never use it. (I even had to look up what 'OV3' meant!)

I do my PP with PS 4, but only really scratch the surface of the facilities it offers.

Perhaps I ought to look into OV3!

Re: Trying to eliminate green cast in portrait.

Thanks Jim. OV3 is my goto tool and I only switch into Elements if I need to use masks to apply different treatments to different parst of the picture. Sometimes I will just use it to mask and merge two different treatments from OV3 where I have got the processing I want but can't specify which parts of the picture to apply it to. I use Elements or PhotoDirector where I need to do spot healing, touch up, or object removal as OV3 does not deal with these situations. I also use Paint Shop Pro 4 where a more direct application of bitmap editing, cloning, or blurring is required as it is quick and easy to use.

Re: Trying to eliminate green cast in portrait.

Having mentioned that I sometimes use PhotoDirector 4, and having 15 minute to play, I thought I would see what I can come up with. This is an easy to use photo editor. There are no picture layers but you can define multiple masks which can each have their own panoply of "regional" adjustments all controlled by sliders (think multi function adjustment layer with layer mask); overlapping masks apply adjustments from all overlap areas. Masks can be painted on with a brush or by selection.

Global adjustments:
Red: -25
Orange: -9
Yellow: 25
Green: 56
Magenta -3

Hair and Eyelashes:
Clarity: 100
Red: 3
Yellow: -9
Green: -25
Purple: 46
Magenta: 63
Sharpness: 5

Neck:
Green: -100

Lips:
Clarity: -100 (to soften)
Vibrance: 57
Red: 50

Eyes:
Brightness: -7
Clarity: 63

Face and Neck:
Clarity: -69 (to soften further)

I then used the eye blinger to brighten up the whites of the eyes a tad and the tothbrush to give more definition to the teeth. There were some small dark areas in the corners of the mouth cleaned up by cloning other parts of the lips with the object removal tool.

Very impressive 'OM USer'!

I've not heard of PhotoDirector 4 - I'm going to have to look it up.

Many thanks, Jim

Thanks Jim, its always nice to have a good model to work with. PhotoDirector has moved on since version 4, I think it is now on version 9. I got version 4 when there was a good offer on for about twenty quid - last of the big spenders.

As I liked the colour of the dress I got using OV3 I decided to merge the OV3 jpeg with the PhotoDirector 4 jpeg in Elements. I took the opportunity to use the smudge tool to straighten up the lines around the mouth and lips and lessen the reddish tint in her forehead. I don't suppose you remember the actual colour of the dress?

I have rather monopolised this thread [sorry] by posting my thought processes and jpegs along the way but I hope mine and the other replies have given you thought for what you can achieve. Don't be afraid to use whatever photo tools you have available. By the way, I have enjoyed this - thank you for letting us be free with your original image.

No, I wasn't at the function where the photo was taken.

It's been very illuminating to follow your work on this image. I probably need to make better use of the software I have - Faststone (which I rarely use) Lightroom (which I bought, but have never used) and Photoshop 4 (where I use only basic functions).

I'm currently decorating, but when I've finished I'll try the free trial of PhotoDirector.
