Maaco?

What I would most likely do is to use the lasso-tool, quick-mask, or whatever other selection method your comfortable with in Photoshop to select all the areas that you want to change (or conversely mask the areas that you do not wish to change).

Then, I'd probably start with a hue/saturation(colorize) adjustment to get the color relatively close, and then adjust contrast/brightness, etc. until it looks natural...

I like simple erasing myself (tedious whatever method you use. I created this camo texture (I have a cool Script-fu that creates these seamlessly) and then blended it in (many different layer blends and used the original as a displacment map reference too). I also added the OD Green on selective parts by simply doing a hue juxtapostion and erase through (in PS just do an adjusment layer; since I used GIMP, I had to do a Hue shift on a duplicate layer. Just different ways to get the same result).

As far as the result is concerned, yes, it's a sophmorish try (this is just my hobby; lol).

Thanks for the comments Donald/Justin. Again, if my life depended on it, this could be made better. I only approximated Olive Drab. I did a hue adjustment on a separate layer and commenced to erasing as I did before.

I wasn't real careful about masking it - actually its really sloppy but I was working quick.

I converted to BW changed the color balance to max green - Adjusted hue/Lightness then fiddled with the curves until I got the color I wanted.

How is this?

Does you friend just want to see what it looks look in OD or does he want a print?

If a print, then If you want to email me full size images, I would be happy to oblige.

I can also send you this image as a layered Photoshop file with the adjustment layers in tact so that you can tweak it yourself.

Maybe a pink one?

There are several ways to change colours. Most of us know of at least one way. However, for the benefit of others who don't know, the following describes my way of doing it.

Justin sent me a sample of OD colour. From that, I made a clean OD colour sample image

My work flow as a 4 layer process:

Preparation:
1 - Adjust levels of original
2 - make duplicate layer
3 - promote original to a layer
4 - add adjustment mask to original layer (Hue/Saturation)
5 - insert OD colour image as a layer
6 - create layer mask to duplicate of original

7 - Then set layer order as:
Layer 4 (top) = duplicate of original
Layer 3 = OD Colour image layer
Layer 2 = Hue/Saturation Mask
Layer 1 = Original

8 - Getting the right colour:
9 - Set layer 4 to be invisible and layer 3 to be visible
10 - Drag OD colour layer to the edge of an average density portion of the original
11 - Select hue/saturation adjustment mask and tweak Hue and Lightness to match the colour and density of the OD colour. Once happy, proceed to next step.
12 - Make layer 3 (OD Colour layer) invisible and then layer 4 (top layer) to visible
13 - (Important) click in the MASK portion of the top layer to ensure that it is selected.
14 - Select the paint brush from the Tools Pallet. You should see that the colour indicators at the bottom of the tools pallet are black & white. Select black.
15 - (The fun bit) 'Paint' black in the areas where you want the new colour to show.

Tips:
Take your time, this must not be rushed to to a proper job.
You will need to change the brush sizes and the softness of the brush from time to time..
In tight areas zoom in to 200~300% Never work at less than 100%
If you make a mistake, just change the brush colour to white and 'paint' over the mistake.

Remember: With the mask selected, painting black in the image makes that portion transparent so that the layer/s below show through. Painting white restores the image back to what it was...

Learning to use masks is a non destructive way of dramatically changing an image like these. You can always select any mask in the set and re-adjust your work if needs be.

Have fun... I did & Thanks to Justin for letting me have a go on the large originals

EDIT: Save your work often and in a format that will preserve layers. (I use *.psd). Precision masking is a time consuming job. It is heartbreaking to spend an hour or more only to loose the lot because of a power cut/glitch et al...

The object of the exercise was for evidential needs, rather than artistic.

I have just heard that the images showing the vehicle in OD did the job that they were needed for...

Extreme care must be taken in the blocking out - that is why using masks was essential. It is a non-destructive way. If a mistake is made, reverse the 'painting colour' to fix the error.

To do the job properly, each photo took 2 - 3 or more hours. Much changing of brush size and softness of brush depended on the area being worked on - very soft when working in areas where the DOF caused a blurring of image outlines.

Changing the brush softness is absolutely esential. You have to match the edge of the bit you are working on... Imagine a portion of an image that is well beyond the DOF. it is blurred as in 'out of focus' and a brush with 100% hardness is used...Not good.

I had the great advantage of having the full size original high definition images to work on and at times zoomed in at 3 - 400 % to get into areas like the nuts on the mirror stays.
