If I bend the self-imposed rule about being done, finished, over with talking about soft images just a little I can sneak in another little missive about soft focus pictorialist effects, this on that does not involve optics nor filters.
I know I've written about this before, but in light of what I've recently learned about soft focus lenses, soft filters, and image processing, it might be good to make a clear comparison between the various approaches.
What if there was a way to create a "convincing" soft image from a sharp one? I could avoid having to carry a soft focus lens or a soft filter. I might have very good image processing flexibility, right? Color. Black and white. Sharp. Soft. All from a single RAW digital image.
Back in the film days someone popularized an image softening technique that is known as the "Orton Effect." Micheal Orton is the photographer. His film technique is easily adaptable to digital image processing.
Though the previous links talk about the effect as it applies to landscape photography. I'll take a short look at how it might work in portraiture.

Note: The image processing choices I made here are to my taste and are based on trial and error. It's easy to add or subtract "softness" by varying the Gaussian Blur settings. It's a little more difficult to balance the contrast, but I found that varying the Opacity gives me flexibility in this regard. There is no specific "magic" in the fact I used Hard Light and Soft Light blend modes, except they add contrast (sometimes very quickly) at the same time they soften the scene. I could just as easily have added a Normal blend mode layer that was Gaussian Blur'd to help manage the contrast.
Image Comparison ~
As always, click on the image and enlarge to 100percent to see whatever there is to be seen.
Here is the original sharp image -
Here is the Orton Effect processed image -
For additional comparison purposes, here are two more images. The first is soft filtered and the second is using the Pentax 85mm f/2.2 Soft lens.
It should be pretty obvious that each softening technique has it's own "signature" and are each unique in their own way. I'm not sure there's any one "good" nor "correct" nor "proper" way of doing this. It's good to have choices and flexibility in image making, isn't it?
I've enjoyed exploring this topic again. It's something that I've tried to come to grips with over the years and it feels like I'm getting close to being able to fully control an outcome based on a more complete understanding of the underlying materials, science, options, and effects.
I imagine a person could choose an approach and stick with it until they'd mastered their chosen path.
