I am curious to know if and how others are pre-processing their images before publishing.
Here is my experience but would love to hear from you.
Topaz Labs - I mostly use Topaz Denoise and also Topaz Gigapixel with their auto-settings to batch process photos.
Mapillary seems to reject photos that are enlarged using Gigapixel but has no problems with Topaz Denoised photos. Google seems to be okay with any of these formats.
What other software are you using to improve your images and what are your likes and dislikes…
Cheers and thanks
