Discussion Overview

The discussion revolves around finding large images suitable for printing on A0 paper at 300 DPI. Participants explore sources for high-resolution pictures, the feasibility of obtaining free images, and the implications of resolution on print quality.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant seeks large pictures for A0 printing at 300 DPI and expresses frustration with existing search results.
  • Another participant offers to sell high-resolution prints of natural landscapes and suggests that prints made through traditional methods may offer better quality than inkjet prints.
  • Some participants emphasize the importance of 300 DPI for quality, while others suggest that 200 DPI could suffice for certain applications.
  • A participant mentions the required image dimensions for A0 at 300 DPI and suggests looking for stitched photos or graphic designs.
  • There are discussions about the challenges of finding free high-resolution images online, with some participants expressing skepticism about the availability of such images.
  • Some participants suggest purchasing images from street sellers or online stores, while others argue that these may not meet the desired quality standards.
  • There is a debate about the necessity of 300 DPI, with some participants questioning whether the difference between 150 and 300 DPI is perceptible at typical viewing distances.
  • One participant mentions a very large image (272 gigapixels) but notes difficulties in downloading it for printing.

Areas of Agreement / Disagreement

Participants express differing views on the availability of free high-resolution images, the necessity of 300 DPI for quality prints, and the practicality of purchasing images versus finding them online. No consensus is reached on these points.

Contextual Notes

Participants mention various sources and methods for obtaining images, but there are limitations regarding the availability of free high-resolution images and the technical requirements for printing at 300 DPI. The discussion reflects a range of assumptions about image quality and printing processes.

Who May Find This Useful

Individuals interested in large-format printing, photography enthusiasts, and those seeking high-resolution images for artistic or decorative purposes may find this discussion relevant.

I'm looking for large pictures. I want to print a wallpaper on a A0-paper (on a plotter) with the normal 300 DPI. I've used google to search for wallpapers 'greater than' but I end up with pictures that won't fit A0 with 300 DPI (they're in fact smaller).

I'm thus looking for a website for very large pictures (scenery, bridges, cities and so on) that will fit A0 paper with a very nice resolution (at least 300dpi). Can somebody help me?
 
Physics news on Phys.org
I have a few very large stitched photos of natural landscapes that can be printed A0 size at 300 dpi. If you're willing to go to 200 dpi (which still shows remarkable fine detail in a photographic print), I have more choices.

However, I would want to sell you prints directly rather than sell you a huge-resolution file that you can print yourself. These are prints exposed onto traditional photographic paper by laser light, and developed using traditional chemistry; they will look far better than an inkjet from your plotter. Since you want A0, I assume you are in Britain, but I think something could be worked out with a lab there.

In fact, I've been putting together a web store to sell my prints, and was planning to go live today. I feel I should ask the mods permission to post a link, since it's effectively an advertisement. I can certainly PM you, though.
 
Ok, but I'm actually looking for free pictures... And 200 dpi is still less than 300 and is noticeable. By the way I'm not from the UK.
 
a 300 dpi print on A0 paper requires an image size of about 14100 x 9900 pixels. I agree with Ben- you have to deal with stitched photos (or look for graphic design works generated directly on a computer).

For example, Better Light's scanning backs only go up to about 8k x 10k:

One of my colleagues has a GigaPan- the site has some images, but I don't know if they are available for download:

I've made an account but I'm unable to download these beautiful large pictures.

Then maybe you should make the picture yourself. These kinds of things take time and effort to create, not to mention specialized equipment and software (and hiking for miles with said specialized -- and heavy -- equipment). You should expect to pay at least a few thousand dollars for a finished print of such an image.

I doubt you will find large images on internet for free.

I don't understand why you going through all of this when you can simply buy landscapes for less than a buck from those street sellers.

You can also buy landscapes or posters online from websites like demotivators and many-many others. If I were buy one, I would try Nat-Geo or BBC.

I guess there are not too many countries with people named Dirk, like my uncle.

You can buy posters very cheaply, but posters are mass-printed with pigment inks (not a photographic process), and at resolutions of 50-80 dpi. I think the OP wanted something more impressive to look at.

At what distance?! 300 dpi is really, really high. I'd be surprised if the human eye can tell the difference between 150 and 300 at a distance of under a foot.

The average human eye can resolve angular separations down to about 1 arc-minute. At 300 dpi, that corresponds to almost exactly 1 foot of separation. Unless people are going to be burying their noses in these prints, I see no good reason for the super-high resolution.

A normal page is printen on 300 DPI so, that's not really really high. Furthermore, I want to put them in my room where a distance of 1 foot can occur.

Nice, but I can't download it and thus print it.

Read my mind exactly.
