Can a 6000x4000 pixel image be printed 48x60" w/camera having

First, decide whether you will crop - because the aspect ratio of the image is different than the proposed proportions of the print - or will have lots of white space. Either way, you have somewhere around 100 pixels to the inch to work with. Some images will look good if viewers are kept at a reasonable viewing distance, but in general no.

APS-C does not matter. It is all about how many pixels of image per inch of print that you give the printer.

Yes, approx 100ppi is not going to be good looking 'up close'.

You want to keep it 150-180 -> 300 if you can.

• but, shooting 3 different images and merging them. Would that work?

Howard Moftich said:

what is the finished image size (post-merge) ?

Divide that by X dimension and see what you get.

If the *finished* image is 4000x6000, then yes, you're still marginal on quality.

I'm referring to the X/Y PIXEL size of the finished image (before you specify paper size).

The image has no sense of 'inches' or PPI until you specify the paper size.

OK, so the Leica X has an sensor size of 4928x3264

Let's assume NO real cropping but a straight-up 3 image pano merge, you're looking at something like 15k x 10k pixels.

That gives you approx 15k / 60" which is 250DPI which is perfect.

Of course there WILL be cropping as the merge overlaps (you *did* overlap the images enough to get a good merge, right?) but still, I think you'll be fine.

Contrary to popular belief, a 4000x6000 image printed 60" wide will be perfectly acceptable.

How?

To start, your print will end up at 100 ppi. Pretty low, as we want 300 ppi for the best quality. This is where practical viewing distances come in. Seriously, on a 60" wide print, who looks at it from 12 inches away? Snobby pixel peepers that's who. Anyone who is actually viewing the print as artwork instead of a technical printer evaluation will be at least 4-5 feet or more away. Do you watch your 60" tv from only a foot away? No, your realistic viewing distance is much farther away than you think.

So what's the deal? Well, that poor 100 ppi resolution effectively becomes 300 ppi when viewed from just 3 feet away. If you can abstain others from sticking their noses against the print, they will be none the wiser at 3 feet away.

Anyone is free to quickly and cheaply test this. Simply print out an image at any paper size using 100 ppi. So a borderless 8x10 would use a 800x1000 pixel image. Then simply view it from 3 feet or more away. That 8x10 may look small, but it's the same resolution that 60" print will be.

If you can use pano stitching then do so, you'll be much happier with the final image quality that way. But as others have already pointed out, if you're standing far enough away 100ppi will work.

I use pano stitching for all my landscape work and have even done both fine art copy work for friends and studio still life using it with excellent results. If you don't know how it's a useful technique to learn.

Thanks Mike! It will be in a conference room. I think it will be fine but will try a pano..did one 48"x144" first time and came out but landscape

Thanks
