Cool, Luc! Very photorealistic. The lighting and the surfaces are perfect.

Very moody! Looks great. The grass is very natural. And the girl's skin shader is quite good!

It's similar to filters in Photoshop when applied on boundaries of a image with that has no extended hidden canvas. When working on "higher quality images" it's always best have have a unconstricted canvas so effects can "span" off the viewport.

Yes, I also thought about the blur algorithm (for example, Gaussian) in Photoshop, which "paints" the image outside the canvas, so that the application of the filter becomes possible. As a color for the continuation of the image outside the canvas, Photoshop takes the color that was on the edge. In the case of a simple Gaussian blur, this is often justified, since this filter has no function to work only with bright light sources, but there is a need to "look beyond the edge". So we can avoid using a spare canvas along the edges without noticeable artifacts when using a Gaussian blur.

But Bloom and Starburst are a slightly different situation. Here I want to clarify that this is only my vision of this task. Specialization of these post-effects (Bloom and Starburst) - work specifically with bright sources that are visible in the frame. This is an imitation of the lens effect (internal scattering by the radiation detector), for which only what is in the frame is important. Behind the scenes for these post-effects should be taken blackness, and not some kind of "supposed scene" (which is simply necessary for a Gaussian blur). But it's in my opinion, maybe I'm missing some details.

WAS, you talk about a canvas on the edge. Unfortunately, this is not a solution to the problem, because the flash will still arise, it just will appear further from the final edge of the canvas. However, its effect can extend almost to the whole image, especially if the light source was bright enough. This means you need to create a canvas with a margin comparable to the size of the final image itself.

Fluffy Moss Shader v1

Working on another version but my ideas have hit some road blocks. Simple surface shader with complex internal node network. I spend a lot of time on small details and mixing, sometimes it pays off, other times it doesn't.

In this case I find the moss looks pretty good. Even close. And that's at a MPD 0.6 and AA 6 limitation, though I did bump GI cache and detail to 4, and Occlusion Weight (I believe it was) to 2 (feel it helps with fine detail being sharp)

A fountain I'd been working on the textues for a while and a spray I seem to recall adapting from an online mesh or maybe from some one here, there's no readme; once again sigh. The tree is fro 3D EXPORT, here:

the girl from one of those sites with no readme either and Dunes grass04

Very nice, the lighting works really well with the model of the girl and fountain. Is that water part of the object or procedural? It has me confused. The grass rolls very nicely. It just works well, should try and save that density shader haha.

Here a picture rendered by using this canyon scene 

btw GI have been boosted to 1 compared to version in original scene (was 0.85) else it was too much contrasted here for my personal taste..

very cool!
