Thanks for your replies, advice and just generally the time you spent to help me, much appreciate it.
I have printed before, but the largest was A1.
I have also had my images printed this large, but I have not handled the printing process myself.
As far as the size of the resulting print and shipping is concerned, I'm lucky enough to be able to transport it myself rolled up in my vehicle, so I'm not too concerned about that.
Yes 3m which is almost 10 ft long is a significant width, it's for a space in my living room above a sofa which is almost 5 m wide. For a long time I've been looking for a print that would work in that area with an aspect ratio of roughly 2:1, 16:9 would also work.
Mitchell, you raise a good point and I think a highly reflective glossy stock or anything that has to go behind glass won't be suitable for the environment it'll be hung in. My home has lots of glass either side of this wall that will cause reflections that will make viewing the image frustrating.
I've thought about it and I think canvas is the only choice, unless there's a solution I'm missing. I can make a frame myself, probably out of hardwood, likely 20x20 mm square, wrap the canvas around this frame and staple the canvas to the frame. It would be light, strong, easy to hang and adjust and affordable and only approximately $50.
As for the cost of the print, I've been recommended to a printer and they have quoted AUD500 (USD330) to print a 3x1m (That's roughly 10x3 ft) on canvas @ 600 DPI. To me that sounds very reasonable.
Roaming Scott, most of the time it would be from a distance of 5 to 8m (16-26ft).
So I would think 600 DPI on canvas would be sufficient?
Ambient Mike, the image is quite old, however, if I remember correctly, it was captured with a Nikon D800E at close to base sensitivity with decent glass at a close to optimal aperture, so while it is slightly cropped and heavily processed there is a significant amount of detail and minimal noise, one of the reasons for choosing this particular image. The other is the subject matter and the fact that it suits this elongated aspect ratio (imo).
I'll attempt to upload a couple of images, one of the image to be printed and another of the space I'd like to hang the resulting print in.
Again, I very much appreciate everyone's efforts guiding me through this newish process.
