Thread: Getting larger photos printed

In the 24 bit mode you can have a high quality print on a 24"X30" enlargement however it all depends in the type of image that you selected to print.
To give you an example

The image bellow it is heavy in details and I would not print larger than 16" in the larger side on a D300s images @ 14dpi



On the other hand I have a print of the image bellow from the D300s which it is 40" in the large side and the quality it is good because there are no details on it.



I hope that this help

I have printed a few of my landscapes on canvas for display in local galleries, and some of them just don't look good on canvas. It has to be the right image to suit canvas.
I am still printing shots taken on my Canon d60 (6mpx) up to 1mtr x 1 mtr and they look great. Remember, you are not looking at them with your nose on the canvas!
Maybe crop a small section to A4 size and have it printed by a lab to give you an idea of the final result.

Hi Lou

Never had anything printed on canvas. It'd be worth talking to whoever is printing these as to what resolution is needed. Or what rule of thumb applies compared to photographic paper.

The largest print possible depends on the size of your file. Have a play with this calculator. Dpi doesn't equate to ppi.

Printing > Pixels, PPI, & Print Size Calculators

Of course, less resolution is needed as the viewing distance increases, i.e. with larger prints. I have a yellow sticky on my screen, with this table, showing print size (long edge) , printer resolution needed (dpi) and file size needed (ppi).

8" > 480dpi > 3840 ppi
10" > 360dpi > 3600 ppi
12" > 300dpi > 3600 ppi
18" > 240dpi > 4320 ppi
24" > 180dpi > 4320 ppi

I'll let you do the maths for larger again. And when it comes to sharpening for canvas, no idea. Talk to your printer, he/she may well do it for you.

We have a few canvas prints done up and they look pretty nice.

with 24 mp you should be able to get something pretty big.

What you want to look at is resolution measure in DPI (dots per inch). This will give you an indication on how clear the printed image will be.

For canvas printing something like 150 - 200 DPI will give you a high quality image and 100 - 70 DPI is kind of as low as you want to go. For printing on paper I believe you will want a higher resolution.

For example I have a nice image which measures 2848 x 4288 pixels taken on my D90 (lower pixel rate than your camera takes) and if I blow it up to 45x30 inches (1143x762mm) I get ~150 DPI

a quick google search gave me this site HERE which is pretty handy for letting you know what kind of DPI you will get when an image is blown up to common sizes.

You will also want to take note on what resolution they print at but in most cases this is much of a muchness to the untrained eye. I once had some photos printed on canvas and later talked to some guy who said the shop I had them done at does a horrible job... They looked fine to me but I guess he was in the business of printing and offered higher quality printing, it did however come at a much higher price.

A few years back i use to install really big billboards on the roofs of city buildings. When we were preparing them at the factory the images were so pixelated that sometimes even we didn't know what they were showing or saying on it. But once installed and looked at from the ground level it all snaps perfectly into focus.

So even a small photo blown up to a massive size can still look great. It all depends how close people are going to be to the photo.

thats a good point I really never thought about it like that...

perhaps I could print terrible photos and just put a red cord around it preventing people getting any closer than 10meters to view

I have blown up a couple of prints to B0 size (1000mm x 1414mm) from my old 12mp canon 400d. They are a bit pixilated up close but look at it from across the lounge room and you wouldn't know.

It's quite inexpensive to get B0 prints on photo paper at officeworks - about $60ish when I got mine last year. Try it out to see if your happy with it before spending big $$$ on canvas etc.

Lu,

When you bring the triggers back, I can show you a canvas print I had done from this pic of the participants in the 5th anniversary remembrance ride for Bucko.
