On the other hand, upsizing of images files is necessary for making large prints if they are to support close distance viewing. Upsizing images is almost never necessary if they are to be displayed online, or even used in magazines or books.īy the way, that was the coolest book cover: the publisher created a half-inch deep 3D cut-out from the horizontal version of the photograph, which worked really well with this scene because the telephoto had collapsed the scenes into slices of depths. The San Francisco Bay is not a top sailing spot for nothing. I’ve since returned several times to the same spot with better gear, but never observed again the glassy water that created the reflection of the bridge.
I photographed it in January 2004 with a 70-200mm lens and a 1.4x teleconverter on a newly bought Canon EOS Digital Rebel, resulting in a focal length equivalent of 450mm for the vertical image. This is because creating such an alignment of the city skyline with the bridge required a quite distant and un-intuitive viewpoint near the Pt Bonita Lighthouse, more than 2.5 miles away from the bridge. The photographs look straightforward enough, but if you look around the Internet, you won’t see them replicated often for such an iconic subject.
In this post, the third and last in a series devoted to the Topaz suite of AI-based tools, I examine Topaz Gigapixel AI upsizing capabilities and limits using a pair of images of the Golden Gate Bridge.
Even with such a basic task, there is much to be gained by using appropriate apps. If you are making prints, sooner or later you’ll have to upsize the image file.
