I have an opportunity at a one-off job as a colorist for an image. The thing is, this is being decided by having people interested fully color a "test image". The questions I have are:
1. Is this a common thing for people looking for colorists? Or is this a huge red flag that the person is trawling for suckers to color the "test image" for free?
2. If I do go through with applying, would I best explain watermarks etc to the possible commissioner? I don't want to sound accusatory in case this is legit.
