Does Topaz AI Gigapixel AI remove the need for high megapixel camer for amateur landscape photographer? I don’t sell photos, I wish I could, but I don’t know how and am not that good. But I want to get better and print large prints for myself and family. Do I need a full frame or would my sony dsc rx10 iv with Topaz AI be enough to create quality prints?
How big do you want to print?
Your camera already has a fairly high pixel count and you should already be able to print as big as you want, assuming it’s going to be a longer viewing distance the bigger you print.
I cannot speak to Topaz AI but Gigapixel AI does a nice job but it is not always perfect. You need to pay attention to settings and use the before/after slider to carefully check your image. With the wrong settings it can result in less detail. I mostly use gigapixel AI for upscaling AI art though I have done upscaling with it for photos as well.
I find with upscaling photos that if you have the RAW file LR super resolution can be better than Gigapixel in some cases. Even Lightroom super resolution though is not perfect and there are some photos where it introduces more artifacts than I would like.
How big are you planning on printing?
I have gotten excellent 20x30 prints out of 10MP photos many years ago by using a quality print shop. If you have a modern 20-24mp+ camera unless you are planning massive prints or are cropping significantly you probably do not need to use Gigapixel AI.
