K-h, I am really enjoying all your Gif images. Would love to know how to do this.
Still raining, and I am still playing with water.

Thank you Birdie. Sorry, I didn’t notice your question earlier.
Great question. Shooting mostly at 30 FPS, at minimum 15 FPS.
I use a number of apps in combination in my workflow.
First Capture One (CO) to manage the raw images.
Then DxO PureRaw or DxO PhotoLab 7 for de-mosaicking, optical corrections, noise reduction, sharpening.
The images get send back to CO as DNG files.
Next CO sends the images to Adobe Photoshop (PS) for alignment of images.
This is very important because it’s very hard to hold the camera steady enough.
Jerking the camera around results otherwise in jerky GIFs, unpleasant to watch.
I discovered this trick on my own.
Didn’t see this discussed for creating GIF animations.
IBIS results in sharp individual images.
But it does not smooth out from frame to frame as video mode would do.
For alignment to work you need enough things in the images to not change from frame to frame so that they can be aligned. However that does not mean that the object being focused on cannot change. Quite to the contrary. It only requires that the object of the photography has to stay within the background frame. PS does an amazing job aligning the images though there can be quite a few changes in them from frame to frame.
After successful alignment the now aligned images get send back as TIF files to CO.
I then edit and crop the aligned TIF files either in CO or in DxO PhotoLab 7.
Then converted to JPG files they end up in CO.
Up to this point I worked with full size images. In order for the GIF animations not to become too large in size (say less than 100 MByte) I limit the JPG images to a max length of 1500 pixels.
Next the JPG files get send to PS to create the GIF animations.
PS allows to enter a delay after each frame to control time behavior.
So a delay of 0.03 would give correct time evolution for 30 FPS shot images.
For images shot at 15 FPS a delay of 0.07 would give correct time behavior of the GIF.
I then from PS save the fGIF animation on my Mac drive, then on SmugMug.
The GIF file can then be animated in Safari.
That’s it.
Here is an example with and without image alignment.
Good luck.
K-H.
