Hello all, and happy spring!
I come to you again, seeking wisdom... I've had an inquiry from a
client about photographing artwork (painted canvases) for the purpose
of creating prints... for sale. A couple of issues come to mind:
1) The actual photography... I'm assuming hi-resolution is the name of
the game here. Not sure yet how big they want to go with prints... I
think some of the actual canvases are fairly large (30 x40?)
themselves. From the research I've done, I'd think my K-5 is up to
the task... Should I consider renting a larger-format camera?
Alternatively, at what point should I consider 'stitching" images
together for large pieces?
2) Rights. So, this where I really have no idea... my standard
agreement doesn't provide for the sale of my images by clients. How
does that work? I'm reading up -
http://asmp.org/tutorials/licensing-guide.html has been helpful, btw -
but has anyone out there ever taken on this kind of project or
provided that kind of license?
Any thoughts or experiences you have to share are very much appreciated.
Thanks in advance,
1. First of all, consider the resolution of the print & how the print is
going to be made. A 30x40 print at 300ppi is 9000x12000 pixels.
K-5 sensor 4928x3264
300ppi - 16.42"x10.88"
240ppi - 20.5"x13.6"
150ppi - 32.85"x21.76"
I included 240ppi because I believe that's the default resolution
recommended for Epson printers. Take that with a grain of salt, I'm not
certain about it.
When I was running the photo-lab, I could make an acceptable print on
Kodak glossy paper (C-print, aka RA-4 photographic print) with as little
as 150ppi given the right image.
If you want a 30x40 @ 300ppi resolution without up-scaling you'd likely
have to stitch. Figure at least 3x3; 4x4 might be even better.
2. First question, does the person who wants you to photograph the
artwork own the rights to the artwork? Is this client the painter or
someone who bought the painting?
Assuming the client owns the rights to the artwork, I think you're
looking at "work for hire", and the person who is hiring the work done
will own the rights to the photographs. You may want to retain some
rights to use the image for self promotion. All that should be spelled
out in detail in the contract.
Charge accordingly for the taking and for the post-process assembling
the print-ready image.
