DxO Optics Pro

Impressive French RAW development software.
It is no exaggeration to say that I was able to adopt a digital single-lens reflex camera because of this software.
Regardless of the sensor size, it is difficult to take a clear picture with an ultra-wide-angle lens. The LUMIX G series solves this problem well, as previously introduced in the LUMIX G1. It is an epoch-making system that seamlessly corrects various lens aberrations inside the camera.
DxO Optics Pro introduced here is, simply put, software that performs these functions during RAW development. Various camera and lens combination data is built into the software, and distortion, peripheral illumination, chromatic aberration, peripheral blur, etc. are completely and automatically corrected. This is really inspiring. In addition, shift correction, horizontal and vertical fine adjustment, etc. can be corrected intuitively and perfectly.
The SIGMA 12-24mm lens I'm using is super wide-angle, but (because?) it's a fairly problematic lens. First of all, there is a very large drop in the amount of light at the edges of the lens, and images around the edges tend to flow easily.
However, if you stop down to f16 and use it together with this software, it will quickly turn into an excellent super wide-angle lens with almost no optical defects.
This software is not without its flaws. First of all, the processing speed is extremely slow, probably because there are a wide variety of correction items.
As for the image quality, the resolution is quite high, and the finish is flashy, but the impression is good. In addition, the DxO Lighting function is excellent, and it is quite useful because it can be easily brightened as if the auxiliary light was used in the reflector version. To be honest, it is difficult to do the same processing in Photoshop.
It can be said that it is the strongest architectural photo development software.
If you look at the completely distortion-free examples of Verde Nakayama and Tokyo Great Visual , I think you can feel the effect.
