Some information on the specimen submitted

This is a pretty little plant from forty to sixty centimeters in height. It is very similar to Viola odorata, with whom she frequently hybridize, even under natural conditions, making the determination confused. The essential difference, according to the flora of Gaston Bonnier and by the Botanical Society od the British Isles (http://www.bsbi.org.uk/html/plant_crib.html) is the presence of stolons at the base of the plant for Viola odorata and Viola hirta not. Here, there was no stolon; flowers had no smell, so it is very likely Viola hirta.

The shooting conditions

The shooting was carried out by relatively covered: the lighting was low and the illumination by the sun low. With the 50 mm macro, I open at f / 2.8 (brightness) and photographed at 1 / 200 th of a second (to avoid shake), with a sensitivity equivalent ISO-100.

Obviously, the result of F / 2.8 is a depth of more limited scope, but ultimately, apart from the left petal, the flower is almost clear.

The next time I take advantage of a sunny day, early morning to redo the shot, in f / 8 to f/14, and with the tripod. With an additional test telephoto 300 mm, "to see".

Thanks for looking.

Hi Philipps

Your notes are very elucidative about the image, and the difficult to acheive it, but I think the result is great!
nice colors, very good sharpness and I like the DOF where only the object of interest is in plain focus...

well done!

Hola philippe

Que bonita flor, con ese colorido tan intenso, no la había visto nunca, con esos pequeños pelos.

Realmente bonita. Muy nitida.

Un saludo Antonio
