Post your photography!!

Hey folks....

Is anyone in this group regularly using DARKTABLE on Linux? I just started using it a week or so ago. I might have some questions...would be neat of someone here was a experienced user. I am coming over from Lightroom.
Cheers!

Don't know DARKTABLE.
I've been using Lightroom since 2010.
Been using Photoshop since 1989. Before it was released to the public.
 
Doing de-noise last seems unusual to me. Can you explain more?

I de-noise in LR on almost anything with noise.
It will sharpen up and enhance contrast to the images and you can even make the images even more sharper.
Overkill, but I'm usually pixel peeping at high resolution.

btw... I was the previous president of the Maui Camera Club (since 1936).
I taught LR, PS, photography and stuff.
Created and made the website. Sadly it went down downhill after I left.

I've had the cameras out on the balcony for most of the afternoon. Random lightning strikes have followed along with the storms, and at times when you'd not expect it, such as when a storm isn't really that close.

The TV towers on the west side of Madison have been popular today. I have several of these.

This was off to one side of the frame, thus the vertical. I'll have to remember to center the frame on the towers because they're probably going to be hit before anything else. Will be breaking out 70-300 in the future, but that damn 70-350 APS-C lens shows severe pin cushion distortion on a full frame. I'll have to fix that, if I bother. The images are ok, but nothing to write home about. Darktable doesn't have a profile for the 70-350 either, so no correction.

That looks like just the right amount of adjustment. What camera are you using? It depends what camera I am using to expose for and keep in mind to adjust for dynamic range.

That camera is a 2017 Sony A7r3. Sony 16-35mm GM, f2.8
No processing (lit by passing cars). Straight one shot. Long exposure.
Normal processing
Extreme

You make the image."

I'm still plugging away at figuring out how to use the 20X and 50X objectives I have.

I tried downscaling the images, and it works pretty well. I'm shooting with a Sony A7R IVa which has a 61 MP sensor. The pixels on the sensor are very small, which means there's diffraction issues on high magnification macro photography. Downscaling helps reduce diffraction in a way that's similar to using a camera with a sensor with larger pixels (somewhat like the FLIR camera I have).

This is a horsefly wing after the downscaling the RAW images to TIFF files and then processing the stack of 101 images in Zerene Stacker.

There's a lot of dirt on the wing, and it's reflecting a lot of light around the spikes on the edge of the wing that causes problems where it wrecks detail and clarity. Some of that was due to reflections on those spikes as well which means I'll be adjusting the diffusion on the flashes.

I'll clean the horsefly in an ultrasonic cleaner and try it again.
