Real Digital Zoom App on 3Gs?

Cropping and enlarging the image IS "real digital zoom." You lose resolution because pixels are cropped out. This is the same on any camera or phone that does digital zooming - there is no other way. It's a gimmick.

If those apps just crop and don't enlarge the image to fill the screen, they aren't zooming at all!

Camera Zoom and Camera Genius do actual digital zooming, FWIW. You can achieve the exact same effect "post production" by manually cropping and enlarging an existing picture in Photos.

Do you have Zoom enabled in Camera Genius settings? Sliding the displayed zoom bar will zoom the image.

If that is the case, there is something malfunctioning in your phone and you need to do some troubleshooting. Try the following steps as needed:

1. Reset the phone - press both the home and sleep/wake buttons until the Apple logo appears.
2. Restore in iTunes using a backup
3. Restore as a new iPhone

Apparently, sarcasm isn't your thing. I was responding to your rude question asking if I "actually" knew what I had told you about that app.

Most of these apps will crop without zooming, if that's specifically what you want to do. However, they also "zoom" by enlarging the image. Of course, it requires the ability of the user to follow simple instructions and comprehend the process.

If you really don't want to bother troubleshooting your phone and want to fool yourself into believing that all these digital zoom apps don't even zoom, so be it. I'm done trying to help you.

So, when you offer help to someone, telling him how something you use works, and his response is to ask you if your "actually" use it (implying that you were fabricating), you wouldn't consider that rude? Or is it not rude only when you are the one posing that question?

For the sake of dealing with the nonsensical misinformation in your post that might confuse others reading it, I will clarify this issue.

First, you seem to have no concept of what "zooming" means. To say "some zoom without resizing" makes no sense at all. When these apps zoom, the image you see is magnified and continues to fill the screen. If they were "cropping without resizing", there would be no magnification and you would just get a blank area around the un-cropped part of the picture.

That is exactly how Camera Genius, and Camera Zoom work, when I "actually" use them. When viewing the real time image, sliding the zoom slider magnifies the image while still filling the iPhone screen. The overflow portion not seen is cropped and not saved when storing the picture. This is why digital zooming is a gimmick - you actually lose pixels and resolution.

This also ties into the definition of image "size" vs. enlargement, which you don't use consistently or don't understand at all. The "size" of an image as it appears on a given screen is relative to how it's enlarged and displayed. The technical definition is the number and height/width ratio of pixels. When you digitally zoom, there are fewer resulting pixels and actual size is reduced.

Any app that claims tp maintain the same number of pixels after digital zooming is either saving the original un-zoomed image or interpolating phony pixels that don't represent real image information.
