IMAGE RESOLUTION:

 
Low Resolution Photos and Images

We receive dozens of images from customers asking if they can be enlarged. Most of these images are obtained from websites or scanned in from a magazine. Images need to be at least 200 dpi (dots-per-inch) for purposes of enlargement, and 300+ dpi is even more recommended. (On a computer screen this is really ppi or pixels-per-inch. Dpi or dots-per-inch technically relates to a printed picture. Most people just say dpi when refering to either situation.)

Exactly one year ago in our image resolution newsletter we explained about image resolution and how you can find the image resolution values of a digital picture. We are finding that even when we refer our customers to this article, it isn't explaining what is really happening in terms of why an image with low resolution cannot be enlarged. This newsletter will explain more about why low resolution images are not very useful for enlargement purposes.

Digital images can appear beautiful to the eye and still be very "lossy" in their actual content. "Lossy" means that the image is saved in a format that is stripped of a major amount of content. The popular JPG and GIF image formats are known as "lossy" formats because it is easy to decrease the substance of images down to the smallest possible size that still "appears" satisfactory. Images in these formats can appear substantially attractive to the human eye and still have a lot of their image information stripped out of them. This is done so that their file size is smaller and they load on web pages quickly.

Images scanned in from magazines or newspapers are also low resolution images. They were printed to save ink yet still appear adequate - even very pleasing. Take a look at the image below. This appeared to be an image that we could enlarge big enough to build a floor-to-ceiling wall mural with YottaPrint. We scanned it from a magazine advertisement using a new scanner at 600 dots-per-inch, a resolution so high that it made the file size very large.


Original Image - Scanned in at 600 dpi

When this original is enlarged, the lossiness of the original is evident. Since the original was a low resolution image, there simply was not enough information in the photo to enlarge it satisfactorily. See the two examples below. You can clearly see what the human eye missed:  dots in the original that are not visible until the image is enlarged.

As you can see, when a low resolution image is enlarged, even the best scanned image using the best photo enlargement software (Imagener, of course) is only enlarging content that simply does not exist - pulling apart what is there and revealing what is not.

The high resolution scan served to create a really detailed image of the dots that the scanner could "see," then the enlargement process perfectly enlarged the dots. Images taken from websites can often be much worse than this, completely coming apart into large blocks when enlarged. This is because in their original form they may look okay, but the human eye is really looking at very little actual digital content.

Again, the original image in this example was scanned in at an extremely high resolution - 1200 dpi - but the beginning image just did not have sufficient content for image enlargement purposes even though the human eye sees a beautiful picture in its original form. If in this case the picture we scanned had been a glossy actual photograph with at least 300 dpi resolution, the image could have been enlarged or used to create a beautiful wall mural.

THE ONLY WAY TO PUT AN IMAGE ON A WALL
Kneson Software's YottaPrint is still the only reasonable way that anyone can possibly put a picture on a wall from the floor to the ceiling. Before now, there has been no affordable way to get an image onto a wall as a wall mural. YottaPrint - Print Wall Murals and Print Posters from your printer
In our Volume III, issue 1 newsletter we wrote about the Magic of Modern Murals explaining how a wall mural can dramatically change the environment of an interior room. Our YottaPrint customers have reported that this software is truly changing their interior spaces.

Yottaprint extends the Imagener technology to one of its most practical applications - printing wall murals or posters from your own printer. YottaPrint allows you to print any image as large as you want and seamlessly assemble the image temporarily or permanently on wall surfaces. YottaPrint is intended to allow you to create great looking wall murals with just normal printer paper. You can of course use higher grade papers, and/or photographic quality paper with a high resolution photo printer for even better results.

Follow the instructions for putting up wallpaper - with the only differences in materials and procedures described on the YottaPrint help page - CLICK HERE.

You can create an even better result if you have one of the modern wide-format printers on the market today. Just in the last several years a whole new line of printers have been introduced that print on paper that is wider than traditional 8.5" X 11" printer paper. With one of these modern printers and YottaPrint you can cover large wall spaces with pictures or photos that have deep personal meaning instead of a painting or poster that doesn't relate to your life.
