**FEATURE REQUEST** Would be very useful to be able to compensate for the loss of sharpness due to heat convection / atmospheric conditions. These types of aberrations are typical in wildlife photography, especially over the body of water, or even able the grasslands. ---

This sounds like an interesting idea! I see there’s an old paper that discusses some considerations online (at least for video) - wonder what implications for current day still image sharpening models (if any). Apparently there’s a PDF of it available at: [https://www.researchgate.net/publication/368308523\_Sharpening\_and\_contrast\_enhancement\_of\_atmospheric\_turbulence\_degraded\_video\_sequences](https://www.researchgate.net/publication/368308523_Sharpening_and_contrast_enhancement_of_atmospheric_turbulence_degraded_video_sequences) # Sharpening and contrast enhancement of atmospheric turbulence degraded video sequences - January 2010 - Conference: Proceedings of the Twenty-First Annual Symposium of the Pattern Recognition Association of South Africa - At: South Africa Authors: [![B.D.

This turbulence causes a phenomenon called heat shimmer which appears as a blurring and a wavering geometric distortion of the target scene which limits the effective range of the imaging system. We explore an image processing approach to mitigating the blurring effect of this distortion by using a blind deconvolution technique to sharpen the video signal and a dynamic illuminance-reflectance correction technique to improve the signal’s contrast. The algorithm is implemented on a Graphics Processing Unit to achieve near real-time performance. ---

Thanks, I hope Topaz team is seeing this. P.S. I can’t vote for my own topic:) ---
