Renaissance fair with the Leica APO-Summicron-M 90mm f/2 ASPH lens and Topaz Labs Sharpen AI


I have always had a hard time correctly focusing fast manual lenses. My hit rate wide open is about 50%. With the latest developments in image processing and AI, I started experimenting with different tools that can fix blurry images in post-production. The first tool I used is the new Topaz Labs Sharpen AI that was announced a few weeks ago (you can get a 30-day free trial). Here are some of the results I got - I worked with the original DNG file directly in Topaz Labs Sharpen AI and I did a JPG export without any additional editing. For comparison, I also generated a JPG file in Lightroom without any modifications (click for larger view):

All of the above images are cropped for better comparison. The full-size JPG files can be found on Flickr.

My main complaint about Topaz Labs Sharpen AI is the processing time - I have an 8 core iMac Pro with 64 GB of RAM and it still takes a while to process each action (usually over 1 minute when working with the original DNG file).

Topaz Labs just released Gigapixel AI 4.0 - this is another machine-learning enlargement software solution (existing customers can update for free, for new users Topaz is offering $20 off until April 1st):
