View Full Version : Removing Colours from jpeg
06-23-2008, 09:30 AM
I have a rather complicated piece of artwork that needs to be edited. The problem is the only files I have are jpegs and pixelated at that. The the colour blue is to be removed and a white background turned transparent for screening purposes. The selective colour tool is not working out so well, and the replacement colour tool, well, I won't go into the headache that's giving me. In the end it should be 3 colour, red - orange/yellow - black.
I tried simply creating a new document, rewriting all the text and making my own colour boxes, but there is a image of a burner that needs to be transferred over and when I try to get it, it always just looks bad. Also the logo needs to be transferred over and gives me the same problem, pixelated with sharp edges.
I have attached the file (with blocks covering the name, etc)
Basically I need to know if what they want me to do is even possible.
an odd request from someone using the handle "photoshopdesigner"
Without a better original, you're pretty much hosed into either extensive retouching -- practically rebuilding the whole graphic ... or starting from scratch, building the graphic using vectors, then colorizing.
If it were me, TIME becomes the issue -- either solution above is going to take hours and hours.
If the client wants a "photo" rendition of the object, then I would recommend the most effective, quick and inexpensive solution would be to RE-SHOOT the object on a white-out background, then build in the background.
Otherwise, get out the Pen tool and start rebuilding -- once the client knows it's going to take a couple of days of hard work.

First I would like to thank you for answering my question. But I gotta say, not everyone can know everything, and after reading all of my post, which surely I assume you did, I was asking if there was perhaps some secret I did not know about that would save this person my time and their money.
That being said, they won't talk to the previous designer to get the photo but a pen tool recreation won't cut it for them either. I suppose I have to tell them this can't be done through the computer magic.

Dont' know if the result can do for the client but I did try the color replacement tool. Run it a couple of times with moderate fuzziness.

Technically, its not a complicated piece, you are making it complicated because you are using the wrong tools to do the job.
The first problem you are getting into is that you are using a scan from pre-screened art, in other words this is a picture of a printed piece, so you have screened art that is further complicated by the low resolution. You can thank your cheap client for that.
Personally, I would build everything you need in a page layout app like InDesign (or Illustrator if you have to) and then import the image as a graphic. If you use the pen tool to create an outline of the original and save it as a clipping path, you can import it into InDesign and apply the clipping path having built the background gradient already in InDesign.
As far as knowing everything, welcome to the world of comercial art. If you want to be a successful designer, you better get proficient in a number of programs and give your Photoshop a rest. I don't know how well you know InDesign, but you are looking at maybe half an hour doing the text and background work (and most of that would be typing), another half hour to do the clipping path and then maybe an hour to recreate the logo in Illustrator as vector art (depending on its complexity).
Despite what anyone says or thinks, having a computer and a couple applications does NOT a designer make!
