There should be at least a month's post-release silence for each issue! I'm phoning my post office first thing tomorrow!

Looks like there is an article on digital art by our own @el48tel.
I recognise his avatar in one of the images.

Well done!

Thanks Teg!

Interesting article Terry. Some of my colleagues in my research group Cardiff University worked on nonphotorealistic rendering - computer algorithms that take in a photo, and automatically re-render it in an "artistic" style.

Below are one or two results from one of my photos; if anyone else wants to try, you can upload your own photos at

Thanks Ralph
I'll try those out and forward the link to my Art colleagues

BTW .... how did you know my old "handle"?

This is really interesting Ralph, thank you for sharing! I didn't read the details, but it feels very similar to the style transfer in deep learning area: https://www.tensorflow.org/tutorials/ge ... e_transfer

Edit: Results from an app called "Deep Art Effects" (Deep Art is the term worth a look!):

Original photograph of my Fenestraria in flower (absolutely not the quality you're used to on this forum!):

And the "Deep Art" collage based on it:

Edit: I just reached Terry's article in CW - it's absolutely a coincidence I posted the collage above, it does indeed seem to be the best form to show this art technique! How they say - great minds think alike!

The photo on the front cover had me stumped - all I could come up with was a hybrid Copiapoa Krainziana / Cinerea but the background coast didn't fit in. I didn't even consider Melocactus. For an amateur society, we're producing a very professional magazine.
