Scanning & Resizing Evidence Photos: Maintaining Quality for Larger Format Reprints

Hello. I apologize in advance if this is not the place for such a question. I wanted to find out if it is possible to scan a photo in the format of an evidence photo and enlarge it in order to reprint it in a slightly larger format. Basically, I need to develop photos at the photographer's without taking a new photo. If it is possible? I heard something like that about my ears. I mean to maintain the quality of the photography, won't such a procedure spoil it? I will be grateful for your response

You cannot scale a physical photo to a larger size without losing quality. A good photographer might also use some processing program, but it would be cheaper to take new photos.

1. If you are scanning, scan in the highest possible resolution and the highest, the so-called dpi, ie dots per inch. you can make smaller with the bigger one, but vice versa, you won't lose quality
the resolution is enough, the larger size is 1920 and the dpi set to 300 will be ok.

Scanning should be done at a much higher resolution to eliminate various artifacts resulting from the scanning process itself. And printing even this size of photos shouldn't be a problem. However, usually such a raw image after scanning also requires a few adjustments.

There are also several specialized programs that deal with image enlargement using the best methods of generating or supplementing image fragments. Unfortunately, I only read about them and I have no experience working with them.

Today, when digital cameras are widely available, one can also try to photograph such an developed / printed photograph as a pseudo-scanning method. Of course, you have to experiment with lighting so that there is no reflection of light, etc.

Buy a bun and turn it into a loaf of bread. It's not possible. What format are you interested in?

I need a 3.5x4.5 format to enlarge to 4.5x6. I have to do the whole procedure at the photographer's anyway, because I need to print these photos later. I know it's better to take new photos, but at this point I am not able to. therefore I am considering another solution

I really realize it's easier to take new photos. I don't like making my life difficult, I just can't do it at this point. That's why I wanted to take advice from people who know it or are interested in it

The quality will not be so bad as to disqualify this method immediately. For a friend, I made such enlargements from a photo that she had in one copy and additionally pinned with a stapler and, after a minor treatment, it was possible to look at it.

A separate issue is the requirements of a given institution in a situation where photos are to be submitted as an attachment to an application. Things can get mixed up here, and they may question a photo you think will be acceptable.

Is it not possible to get to the file from which this print was made? In most cases, photographers keep the files and they can be purchased even after a long period of time.

Eeeee I thought you wanted to enlarge to 20cm.

this is about 1.28 it's not a problem write what program do you have a graphics file viewer ??

unfortunately I can't get to the file. Image file viewer? basically I wanted a finished photo to be taken to a photographer to take care of it. someone who knows the case

fuse09, I don't understand your prolemu. If you have a scanner or a digital camera, why take the photo to a photographer to print it? If you scan a photo, as the previous speaker wrote, at 300 dpi, you already have the file ready for printing. Because I assume you have a printer. If you still want to improve the quality, I recommend PhotoZoom Pro. It has several algorithms for improving the quality. But I think with the 4.5x6 format it doesn't make sense. Regards.

I also stopped understanding my colleague's fuse. Take a picture with your camera or mobile phone and take it to the photographer. He will know what to do with it. I think that we will not advise my colleague on the fuse more.

Probably too late, because people need such things "for yesterday", but if the photo was taken at the same photographer's, where it is to be printed, the bigger one, it's worth asking. Photographers I know have an archive of photos they took, and this is a matter of entering the date and finding the photo on the disk, most often it is the original + a copy prepared in the ordered format. The photographer will be happy to print it in a different format, of course for the right price. It is really worth checking when the photos were taken, "probably this year in April" sometimes it turns out "last year in March"
