Saving RAW size and resizing in ON1 RAW Resize: I have a bit of a problem figuring out how to make a very large print using a shot from my Canon 70D which has 20.2 MP. RAW size image...

I have a bit of a problem figuring out how to make a very large print using a shot from my Canon 70D which has 20.2 MP.

RAW size image is 5472 x 3648.

Assuming an image is well in focus, after processing in LightRoom, what is the optimum size I can export the image at 300 dpi before going to ON1 Resize and enlarging it to, for want of argument, something like 16" x 24" or larger?

Any help would be much appreciated. The techie stuff gets me every time.

How big a print are you going to make?

You don't need 300 ppi.

Lightroom is a great program, but not for finishing. You can get more sharpness if you use On1's dynamic contrast and other detail enhancements. Many people love resize for making larger prints, but truth be told, 5472 x 3648 is more than enough for anything you want to do. Large prints are generally viewed at greater distances, and the eye cannot resolve 300 ppi fine detail at 10 ft, which is a good viewing distance for a 40x60 print.

This should help clear things up a bit.

a 16x24 only "needs" 80 ppi for the perception of sharpness, and your image size will provide 228 ppi, which is way more than you need.

When you want 24 inches at 300 dots per inch just multiply 300 times 24 and that tells you the number of pixels (dots) needed for that side.

Do the same with 16 inches.

You want to resize to 4800x7200 pixels.

Which totaly ignores the OP.

One way or another if it is printed on a Canon printer (300 PPI) the image will be resized to said 4800x7200 first.

In the link you provided it says:
If you enter a resolution that's unnecessarily high, your eyes will not see any improvement in the print, and it will take longer to print.

So are there any drawbacks to increasing the ppi, if you have the print made by a company. Would the company charge more if you want more ppi?

The printer will resize the pixel count appropriate to their printer. Sending an image with too many pixels guarantees it will be down sized and lose resolution.

Thanks for all these answers. I print anything 13x19 or smaller myself. I always print at 300 dpi. It has always been my understanding that this is the optimal dpi for printing. It always gets complicated when people ask a simple question. I'm trying to get a simple answer. So let's try to be specific. I'm blowing up portraits.

Question 1. How big in inches can I make a photo at 300 dpi shot with the Canon 70D? That would be sharp and unpixilated.

If the biggest possible size isn't as big as I want it, then presumably I can make it bigger in ON1 RAW.

Thanks for any assistance you can offer.

PS, I'm sending the work to a local lab for printing on deep matte paper.

First off, do not bother going to ON1 resize. Lightroom will do the upsize for you when you specify a certain size; it does a great job at upsizing. 18 x 12 is the print size intended for the dimensions you state so you are not really upsizing much at all. If the print is sharp you should not have a problem. I've upsized many, many times straight from LR without issue. You can also choose to print at a resolution under 300ppi but all the printers I've used seem to want that 300ppi, but printing at 240ppi should not be a problem.

12 x 18 is the answer to the question. The way you asked it it was simple math.

You may have had something else in mind???

As per via, it would be 18x12, not 12x18. ;-)

I look at it like this. First, I think that RAW is RAW and changeing resolution is done in the output product, like a JPEG, not to the RAW data. Next, simplify the math. An image that is 6000x3000 ppi (pixels per inch) at 300 ppi is nominally 20" X 10". So you could print that image at 20x10 inches without having to digitally enlarge it. Now add to that the complications with photos taken in pixels per inch and printers working with dots per inch in their output. Simply boggles the mind. And I haven't even talked about my own vision yet, which is less than optimal at my age.

You can get a 12x18 with that size...If you want to view farther away you can go bigger...that also makes a difference (distance to view)

OK, so directly from my original shot raw image in LR, I can export a 12" x 18" print at 300 dpi. If I want to make an image much bigger than that, at 300 dpi, I can resize it in ON1 RAW. Am I correct?

Thank you all for your input.

What the link says is that at a "normal" viewing distance, you are not likely to see the difference. I believe it also says that if you anticipate closer than "normal" viewing distances, then increase the resolution.

No drawback to providing more resolution than needed, and I've never come across a company that charges by the pixel.
