Capturing the Iridescence

Iridescence is a very fascinating feature of feathers in many species of birds from all over the world. Certainly the brightest and most varied examples come from the birds of paradise, yet this kind of feathers are also found in birds that live in a much closer contact with humans, like ducks and chickens.

The former owner of this pair of iridescent feathers was a Pacific Black Duck, Anas superciliosa, one of the most common species of ducks, it is found along every creek and in every park around Brisbane. These two feathers are part of the secondary remiges group, one from each wing and in ducks this group of feathers is called speculum. Each species of duck has a slightly different colour, according to the angle from which we look, we can see a large number of colours, from dull green, grey and brown to a bright emerald green, purple, cyan blue, dark blue, magenta and a warm yellow-green.

Feather iridescence is the right subject to use Phthalo Blue and Phthalo Green with little or no mixing.

Representing feathers' iridescence with watercolours is challanging, one has to rely on the transparecy of the pigments, applying a number of layers of colours making sure to blend them in the right way, at the right moment. For this, I noticed that outside weather conditions also have their part in the painting process. I found particularly difficult to work on this painting during hot and dry weather, while, on the contrary, it was much easier on rainy days, when outside humidity conditions slowed down the drying time. You can probably see the difference yourself, the upper feather was painted on a wet day, the lower one on a very dry, hot day.

A newly opened website about Birds of Paradise gives, among other things, a very clear understanding of how feather iridescence works. The website is also packed with videos and photographs that are truly beautiful and worth a visit.

 And this is a series of eight bookmarks that I just released. They are printed on a beautiful 300gsm recycled paper, you can see more details following this link.

Matteo Grilli Wildlife Art Christmas Ideas

I've been rather busy lately stocking up my online store for the upcoming season, which is always exciting as it is a chance to look back into what I've been working on for the last few years and find a new way to look at my creative endavours. For instance, there was a big painting, a composition of many feathers of different Australian bird species that I was not sure what to make out of it, so I decided to cut out every feather with tiny sissors and mount them on a hard paper board and here we go! A new collection of bookmarks. The same with a few more feathers and a couple of Eucalyptus leaves from a painting that has never been finished.

I also decided to take some more paintings to be professionally scanned and released as open edition archival Giclee reproductions. It was the right time to get this Pale-headed Rosella out there, a bird and a painting I'm very fond of. This bird used to come and visit the big tree in our backyard and this is one of my earliest study of Australian birds. It is now available as small, medium-size and large print.

Probably not so colorful as a parrot, but certainly not less intersting or charming, the Bush-stone Curlews of the first painting of the Avian Faces Series could not be missing from this selection. The four faces of this awesome bird are also available as small, medium-size and large prints.

For those who love the colours of australian cockatoos, here we have the Galahs feeding on the ground after a storm. This painting is also available as small, medium-size and large print.

My last choice was for the Sulphur-crested Cockatoo, who after a feed on our veranda, decided to observe and study myself sitting on the chair in front of him, revealing his curious and inquisitive nature, as well as the other paintings this is also available as small, medium-size and large print.

Each print is individually signed and dated. For more informations regarding sizes and shipping, please follow the links provided.

My work is not over, I'm now organizing for getting greeting cards printed and I hope to be able to release them very soon.

I'm open to suggestions and feedback and I would love to hear from you, 

until next time,

all the best,

M
