Hi. I have a stock photo site that gives photos away for free, and I need to have images I've sourced described and keyworded.
Here is the process: I will share a Dropbox folder full of low resolution images with you, and you will populate the IPTC metadata fields with and Image Title (short title for the image), Description (expanded, but still short, description of what's in the image), and Keywords (generally 8-30 words describing the image). All the data will be embedded in the images, and once you send back images via Dropbox, we will copy the data to the full sized images before we upload to our site.
Regarding keywords, there are tools online to help you do this well. I'm fine with, and would even encourage the use of, tools like this one: [url removed, login to view] These tools make it easy to find common keywords and appropriate concept words, but it is easy to get unrelated terms if you're not careful.
I have several thousand images to keyword at the moment, but I will work on a per-image basis.
Please bid based on an initial batch of 250 images of various topics. All work must be done in English.
Please let me know if you have questions. If you're not sure what the end product should look like, visit any stock photo site and look at how images are described.
