photo manipulation help

PureFire · Post by **PureFire** » 09 Mar 2008, 21:50

hi all...
right, i have a picture of a car that i would like to edit!
mostly, just changing the colour of the car, from silver, to yellow!

how would i go about doing it? where would i start?
i have paint.net, gimp2, deneba canvas 8, and corel draw 8!

which would be the easiest to use?
ive tried looking in the help files and online, but havent found something useful yet!

thanks!

I recommend getting photoshop CS2/CS3.

There is an easy tool to replace the colour.

I have not used these programs except corel, and that would not be of any help.

in photoshop you would use a function called gradient map, there might be a similar function in the other pas, but I am not sure...

outside of a professional environment, how many people would go and splurge multiple thousands of rands on photoshop for something like this?

unless the 'recommendation' had nothing to do with legal aquisition?

@PureFire: Gimp has the same "select by color", (Shift+O), you will find elsewhere.. a combination of this tool, along with the magic wand should see you through. thereafter you could use either the hue-saturation tool or the RGB tools to get the result you're after...

im slightly stuck?
i have pixels that dont want to recolour according to the rest of the car?
and they just happen to be on the bonnet!

i have read through some of those tutorials, but its not helping?

post a link... let us loose on it

in most cases, i use additional layers to manage this sort of manipulation.. purely because you can use a gradient blend, or transparency, to achieve a far smoother result than directly modifying the base image...

alright! thanks... give me a few minutes!
i'll post the original pic, and where ive gotten up to!

Original Picture - Top
My Editing - Bottom

btw, this is the holden coupe 60 concept car, that celebrates the company's 60th year of production!

will have a peek later, but i get why you're having trouble...

the "select by color" tool would be used to select the majority of the target area. you will still need to zoom in and use the magic wand, (shift+left click adds to selection, ctrl+left click removes from the selection), to refine the selection... (in the Tool Options window you can set the tolerance for either of these...)

once happy with the selection, copy and then 'paste as layer'. you can then modify this new layer, leaving the original image intact... once this has been achieved, (and you've aligned the new layer), you can start playing with the various layer blend options in the layer toolbox - if you're feeling a little more adventurous, you could also look at using a layer mask to control the blending...

dude, forget the "select by colour" tool...seriously, it doesn't work. get yourself the "pen" or "path" tool and draw around what you want to change. then make a new layer and quick mask your selection and fill with yellow. then play with the blending options... or use the gradient map tool on your selection...

edit:

that car is AWESOME! Chevy concept coupe FTW!

ok... i think i got it...
but i had to cut the bonnet from another copy of the image and paste it onto my edited image...

how does it look to you guys?

Final edit?

anyways, if someone else can do a better job on this, please feel free to!
thanks!

Did this quickly in photoshop. I might have missed some spots. If you want to use this point 'em out and I will fix it quickly.

That color layer is so rough over the black parts of the image its not even funny! Glad you like it.

Its quite easy in photoshop. You make a color layer over your image, set the blending style to multiply, and remove it where it shouldn't be. From what I understand, multiply literally adds (or multiplies?) the value of each involved pixel to the pixel directly below it. So you get accurate color without actually doing anything.

thanks for the explanation...
you guys have been a great help! thanks again!
now i understand about adding the layers and editing those instead of the image itself!
thanks again!

5 minute gimp effort..

the 7 minute, jamin_za pimped, effort, (because he has special tastes):

selected the shaded areas 'by color', knocked out those parts i couldn't care about, inverted the selection and proceded to remove the pixels around the car using the magic wand. a simple copy-paste thereafter and we could then flush everything surrounding the car, leaving us with a fully textured copy with which to muck around...

the bottom of the grill worries me...

5 min gimp effort is GORGEOUS! :drool:

lol at pimped effect!

i must try this with a lighter yellow as well!
i dont have time to play now, but i'll try again later!
thanks again guys!
