I'm using a low megapixel camera (16mp), just wondering if in post I put it through Topaz Gigapixel to increase the megapixel and then Sharpen AI (if it needs it at all) would make the image look as though it came from a camera let's say about a 20mp image and most of all, clearer and better? Just wondering.

Every time you press the shutter release, the lens focuses an image onto the sensor in your camera where the light is converted into a digital file as measured by the pixels of the sensor and the resulting file.

What would be accomplished by using software to 'add' pixels to the image that were not captured by the camera? These added pixels weren't captured by the camera from the lens. What could the pixels add to the image that the camera didn't originally capture?

The Sharpen AI can do wonders to an image that otherwise should just be deleted during culling. But, unless you've captured Nessie the Loch Ness Monster or Sasquatch and fumbled the camera in your excitement, why not just practice your skills so you capture sharply focused images on a reliable and consistent basis? For general sharpening, rather than image recovery, you probably own software tools already that are more efficient at sharpening images than Sharpen AI.

For digital viewing of images, you'd be challenged to see the difference between a 10MP camera and a 20MP camera. There's no way to look at a 20MP image and say 'a ha' this image is obvious and clearly from a 20MP camera vs this other image from 16MP.

Thank you CHG CANON, I've been following your replies and I think your a wealth of information, may I ask what camera are you using?

You asked about Sharpen AI in the past. There were some reasonable examples presented in that thread. https://www.uglyhedgehog.com/t-611142-4.html

To my eyes, these various examples show my contention that either (a) the image should have just been deleted with no further consideration. Or, (b) the AI 'sharpening' is no greater than could be done by most any editing software.

When you consider these software tools, on increasing the pixel resolution in general, what do you seek to accomplish?

Regarding cameras, my tag-line is current for the 22MP EOS 5DIII and 24MP Sony a7II. I have about 6 yrs of images with a 10MP EOS XTi and 2 years with a 18MP EOS 7D. I can give several examples of the same subject for 10MP vs 22MP or 22MP vs 24MP. You'd never say which was which, without being told, from visual inspection of the digital files.

when I crop I lose pixels, just trying to regain some of the 16mp lost from cropping. The final image is kind of muddy. I must've not kept track of my asking, sorry.

I went looking for examples of your work and the AI question was rather recent. You shouldn't 'lose' anything from cropping, so maybe it would be more effective to look at this issue in more detail to determine was is happening.

Is this to make a larger print ? I believe the software adds pixels via AI & some post work in a program like PS may be needed when you pixel peep. I have never printed larger than 13"x19" & just going on info of watched videos.

Giga is really intended for making prints from cropped images.
Sharpen is intended to repair images not that close to being in focus...it's definitely a hit and miss endeavor.
DeNoise does a better all around job ... if you did your job.

I agree you can't make real data, but I used gigapixel on some Astro images and was quite surprised at the results. The image of the horsehead nebula was now 6? x larger, but looked fine. I was actually quite surprised it worked period since I doubt they trained th AI on such images.

Topaz recommend Gigapixel be the last software modification and only if you are cropping a lot or making a big enlargement.

Perhaps a billboard size enlargement?
