This one really adds to the last post. I think maybe I've had a string of difficult customers recently that's got me thinking about this. They fall into 2 camps:
First is the "Could you just...?" crowd. Could you just airbrush my arm fat? Could you just make my nose less red? Could you just make it look like a sunny day? (All real examples by the way!) All of my pictures are individually edited and I do make a great effort to remove any non-permanent blemishes like spots or bruises. But my prices are based on the standard work I do. Please understand that if I have to make your nose less red on every single photo this add a massive amount of time to the process.
Second is the deal hunter. You know the conversation. "That'll be £220 please." "Oh. I only have £200. Is there anything you can do?" Well yes, there is something I can do. I can not sell you £20 worth of photos. It sounds a bit harsh but my prices are very fair for me and my clients. I think the worst are the ones who ask for the digital file if they buy the print. I only make money from selling photos from a portrait shoot. It might sound very mercenary, but if you want 3 copies of a print, please buy 3 copies of a print. Don't try and wangle the full size digital file out of me under the pretense that you're just going to "put it up on Facebook and that". I will sell you the digital files, but they are deliberately disproportionately expensive. I will only ever sell that once and it could turn into dozens of prints for the whole family meaning I lose out.
You wouldn't take your car in to get new tyres and ask "You couldn't just replace a few bulbs and tighten the handbrake at no extra charge as well could you?" Equally you don't barter with the automated checkout at Sainsbury's to try and get a free tin of beans because you didn't bring enough cash out with you!
I'm a big believer in 'if you don't ask you don't get' so by all means ask. But don't be offended if the answer is no.
Sorry if I sound a bit ranty but it's good to get things off your chest sometimes!
