Client wants canvas print 48x72?

I sell some landscape photos on Etsy from time to time and I received a message from someone wanting a custom print on canvas at 48x72... My image was taken with a Canon 5D Mark III. I have ordered canvas prints from Canvasondemand before but they don't go this large. What should I do here? Will my 5D mark III file hold up to printing this large?

Any advice is appreciated on where to go from here.

Thank you!

The first step is to get a copy of topaz gigapixel. It does an excellent job of upsizing files. I can't help you with a vendor though. Good luck.

You may want to work with the printer - most of the canvas printing sites I just googled recommend ridiculously low minimum resolution for larger prints. Canvas prints generally will not require as many PPI as a gloss or fine art print. Also, the printer will probably have software to up-res the art if it is not high enough in pixel count. In that case, work with them to print a small portion of your image with details and continuous tone (like a gradient from a sky or sunset) at the full, final resolution and inspect that small print yourself to see just how you camera's native resolution prints in that printer's workflow.

The 5DIII has a native output res of 5760 x 3840 pixels. At 72 inches, the native 5DIII image will yield 80 pixels per inch of print (5760 px/ 72 in). The canvas printing sites I was looking at were asking for as low as 60 PPI as a minimum so you may be ok. Again, work with the printer.

After up-resing, it may be useful to add a very slight amount of grain to break up the appearance of interpolated pixels - this might help the image appear more natural.

If you cropped your native file, then obviously you are starting with fewer pixels and you may need to judiciously up-res. You can do this in PS, but if you want an excuse to buy the latest AI-based up-resing software, have fun! Depending on the content of your image, you may find a lot of artifacts for the AI algorithms, so print small crops at 100% of the final resolution as hard proofs before paying for, and delivering, a huge print that looks terrible.

Have fun!

One can get very fine large prints, even from relatively low pixel count original images! Upsize the image to provide the pixel-per-millimeter you desire for the final print size. This is what I have posted on POTN about taking a 12MPixel image up to 20 x 60" canvas wrap, 200 ppi was the resultant print, 67 ppi was the original image pixel density if printed to 60"...I used PaintShop Pro, nothing special to upres. No one -- even veteran expert photographers -- has ever stood 3' in front of the print and commented about pixellation or lack of detail.

Unfortunately the outfit that printed this on canvas is no longer in business, or I would provide their name to you.

If your image is 5760 x 3840 ... 80 ppi will give you the size needed.

It's the viewing distance that will allow for low ppi ... that size should be approx 10' view distance ( 6' x 4' )

I buy all my canvas from Pro Print (https://www.proprints.​com/)

They are exceptional quality and their prices are excellent IMO.

You need a good software to size your image to your output size, others have recommended to go to for it.

Good luck.
