Hi, Leo. I’ve recently come across a number of apps that claim they will transform your poor quality media files into a higher quality format, such as HD for video files. Now, I don’t know enough to say that it’s just not possible, but I do remember a golden rule from my photography days. If it isn’t on the film from the start, no matter how skilled you are in the dark room, it won’t be on the print in the end. That was in relation to the exposure in the film; if you don’t expose the film sufficiently to form an image, then all was lost. Surely, this implies to computer files also. Or am I missing something?
Fundamentally, you are absolutely correct. You can only have so much information in an image. When you take a picture, that is all you have. You can’t enhance it to create more information than what’s in the existing image.
It really annoys me when a police drama on TV has a scene where somebody enlarges an image and zooms in on a tiny area… to find that area is now all of a sudden enhanced and crystal clear.
In real life, it just doesn’t work that way. Still, there are some things that can be done. Let me talk about that for a minute.
Ever since I got a new Acer laptop, an Aspire, two years ago with Windows 7 Home Premium, and I transferred my old files to it, I’ve been unable to open certain files that I receive in email: JPG, PNG, or PowerPoint presentations. I get this message that basically says, “The file .jpg could not be opened because the associated helper application does not exist. Change the association in your Preferences.” Can you explain what this means and how to correct the problem? I work around it by saving the photo, going to the folder I saved it in, and then opening it the way that I would any file or photo.
It’s odd that you can view the files after saving them. That implies that you have the program that you need to view pictures.
Unfortunately, you didn’t mention the email program that you’re using. That plays a key role in this problem. Let’s talk about what’s going on here.
