Has C1 considered adding a gausian blur tool, preferably with the option to feather the effect?

What problem do you see this solving?
Ability to blur all or part of the background of an image. In outdoor photography using my Sekonic 858D in spot metering mode I've frequently measured the dynamic range of natural light as exceeding 17EV, and sometimes well over 20EV. I prefer to use camera systems featuring leaf shutters (for reasons that I don't need to explain to a company that used to be a part of P1). After exposing to the right as far as I dare I can indeed often recover much of the shadow detail and colour, but this comes at the cost of having stopped the lens down to a point where I've got more of the background in focus than I'd prefer, and diffraction adversely affects the entire image. Another way of looking at this is that the ability to separate a subject from the background is often severely constrained.

When was the last time you were affected by this lack of functionality, or specific tool?
Today.

Are you using any workarounds or other solutions to achieve your goals in Capture One?
I can and do use the blur tool in Affinity Photo, it's similar to what is in Photoshop in its' limitations and capabilities. It's often advantageous in both Affinity and Photoshop to create a layer or layers with a mask or masks as both programs allow considerably more control through use of filters.

Location and time allowing I can and have put my digital back on a view camera. While use of a view camera is not always practical, the use of movements can, of course, sometimes be very helpful in minimizing the sort of issues I've described. Where used, the limitations of the leaf shutters available on appropriate lenses are more severe than many more modern lenses that attach directly to a camera; use of lenses with electronic shutters, or the use of the electronic shutter in the digital back yield results that vary over a great range with the particular electronic shutter used.

Are you happy to be contacted further about this suggestion or request?
Yes.
