I have some phone photos (android) that I would like to enlarge, but am afraid will lose their clarity. Has anyone used Topaz AI resize to enlarge these type of photos? Is the enlargement clear or does it have a lot of noise?
I assume you mean Topaz AI Gigapixel. I have tested it only on photos from my DSLR and it does a brilliant job. But how good a job it will do depends on the quality of the input image to be enlarged. It shouldn't matter if the photo comes from a phone or not.
I would think the best option is to download it for the free trial period, enlarge some images with it and see if you like the results.
When I click both your images to view the "enlargement" and then right-click each "enlargement" and select "View image info" I see that both of your "enlargement" images (original and 400% enlarged) have been sized to 640px x 853px for web display.
You can't accurately evaluate how well AI Gigaoixel enlarged the original image.
The only way for a visitor to evaluate the images properly would be to download the original and AI Gigapixeled enlargement and view them at 100% on a screen and/or make prints.
These 2 images could be exactly the same image as far as I can tell by looking at them on my screen.
Pat - Up to 400%, there was no added noise or loss in clarity as shown by my example photos. For some photos I've enlarged, the 400% enlargement actually looked better than the original. At 600%, there was a slight loss in clarity.
AI Gigapixel is now version 2, so if your original download was v1 then you should be able to download v2.
If for some reason Topaz doesn't let you install v2 and you have a static ip address, a common well known workaround is to use a free VPN (Virtual Private Network) so that Topaz sees a different ip address from your ip address they might have stored when you first downloaded it.
You might also have to provide a different email address. There are plenty of free email sites on the www.
