Here is my workflow for the magazines I work for;
I am called with an assignment. Typically, I get all a verbal description of what they are looking for, and brief idea of what will be written, and any emphasis they want to see in the images. For the magazines that I shoot more product based items, I just get an idea of what will be shipped to me, and a general idea of what the article will be about. Some are very specific on what they want, others are very open and ask me to provide the ideas and creativity. I've never seen a draft or finished article prior to the actual shooting.
Depending on the shoot, I will generally shoot RAW, but on some occasions I shoot JPEG if the coverage will be significant in the amount of images I'll need to provide to the editor. Once shot, I edit out any test shots, bad focus, closed eyes, or other issues. I take a second pass at it, and rate all the best shots on a scale of 1-3. Then I'll send the editor the best shots from the shoot for their selection. They are sent via overnight FedEx, or FTP depending on the client. If the images were of a specific item, like a product, artwork, etc, I may only send 3 or 4 shots of that item.
I never send out unedited images. They are all processed for color correction, exposure, saturation, etc, but more importantly processed to match the reduced dynamic range and color space of the final printing process. Many clients want me to convert from Adobe RGB or sRGB to CMYK for printing. This means you need to understand how to do the conversions properly while keeping the colors in check. Some magazines will do this themselves, have an in-house person to do it, or leave it to the printing companies personnel. But either way, they are all processed before I send them out.
For some clients/jobs, IPTC data needs to be entered for captions and general information. Some clients have be provide this in a separate file with filenames as the reference. Others want it in the metadata so it goes with the images. Either way, all that data needs to be handled.
The editor then makes the selection for the magazine. Sometimes they will come back to me for help in selecting, or for additional information on the shoot or images. But generally, I don't know what images they have selected till it shows up on in the book store newsstands.
My challenge is I am a color blind photographer so I struggle seeing slight tints in my images. I'm not comfortable making the final call on the image with out someone double checking skin tones or if there is a tint.
Color can be a big issue with stuff that goes to press, especially if you are doing conversions to CMYK for printing. You use the color balance tools in PS to adjust your colors, and can calibrate your workflow to keep the color consistent. But its probably best to have someone check it at your end before it goes out. And you would need to know now to correct an image if the editor comes back to you and says that many of the images have a green tinge to it. You need someone that can assist you in figuring out which ones are green, and making the right corrections.
I would guess that you could find an independent retoucher that can help you with that portion of your workflow. Checking your select images for color casts and correcting them for you. Just include them at some point of your workflow before you send the images off to the magazine. I'm sure something like that can be worked out for you.
