Unfortunately, it’s one of those things that you pretty much have to do as a sales agency. I’ll make it light enough to the point of being subliminal in the final version…that was just to show object placement.
I frequently have to work up photos of fishing trips and whatnot for clients, to remind them of the good times that they had at such-and-such an event, and one of the requirements from our end is that the logo has to be in there. I’ve figured out how to do it so that not a single client has ever even noticed it.
I agree they’re obtrusive. But they cost money to create, and serve a function to keep the business alive. I try to be delicate about it.
