Hey.

I'm printing out a large family shot, with about 30 people in it and i had to crop the image to get it into a panoramic ratio.

I'm printing out the canvas 20x40, and i was wondering if 127.9 DPI would be enough for sufficient detail?

Should i upsize it first?

Thanks

Depends on the level of detail you want... but if you already have the image, nothing you can do about it. Don't bother resizing it, most printers do a better job than you do (when smugmug uses bay or ezprint, they use lanczos resizing to get to the printer's preferred size, and lanczos>>>>>>fractals>>bicubic)


I don't hate macs or OSX, I hate people and statements that portray them as better than anything else. Macs are A solution, not THE solution. Get a good desktop i7 with Windows 7 and come tell me that sucks for photo or video editing.

Yes. Let the canvas people do it, they do it all day every day.

I did a canvas print from a portrait out of a 400d at 24"x36" and it worked out fine (works out at 108 DPI).

Just make sure there are no small details that you didnt notice prior to sending it for print - I didnt notice an area that i hadnt masked while doing some of my alterations - fortunately i caught it before printing! It would have looked awful if it had gone to print with the error though.

canvas guy that i use says 100dpi is normally fine

bearing in mind that you do stand so close to a canvas.

Dynamite is right here - generally viewing distance is a few feet as you normally blow your image up quite large. You'd actually be surprised about what you can get away with on canvas - we get some really good results with JPEGs as low as 1mb blown up to 60 x 85cm! Obviously if you have larger files you can get pin sharp images on canvas contrary to the believe that the texture dulls the print quality...
