It is time to get out the Xmas wrapping paper for the happiest season of all. Have a wonderful and happy day!
A lily with a daffodil refraction reflected onto a black shiny surface.
My single image with post processing in Photoshop and Topaz.
These are antique cordial/liqueur glasses I inherited from my grandmother many, many years ago.
This image congers up memories of when I read The Night Circus by Erin Morgenstern. A very magical book and a good read!
Shot for Smile on Saturday, Sept 4th theme of Many Identical Objects.
La réfraction peut se définir comme la déviation que subit un rayon lumineux lorsqu'il passe dans un milieu de densité différente.
flowers in water drops,it's nice symmetry i think,one day i will have a blue sky and clouds in one of these!😊

Have a great Tuesday everyone!

En cette période de confinement et de brouillard, pourquoi ne pas s'initier à la photo en studio et à la réfraction... C'est une expérience que j'ai trouvé plutôt passionnante et surtout riche d'enseignements.
Nota: Vous pouvez trouvez l'explication sur la chaine " coaching-photo" sur YouTube 😀, le coach est génial !
camera is my red d5300,water used and with the same equip as the dandelions,bellows etc.,i used a thin linked necklace chain thats been left outside for a long time to get weathered and textured,its from the same shoot as the dandelion one previous,i just put a dande/drop in front for the other.thanks.ps,the one drop fell out of position lol!😊
Raindrops
Another raindrop image from yesterday.
Posting early as I will be out for most of the afternoon.
Catch up later.
I just can't help myself, when they're sparkling in the sunlight like this I have to take a picture :)
The light of late afternoon illuminates this window in the medieval Abbey of Santa Maria of Alcobaca in Portugal into a refraction of beautiful colors.

Messier 97 (top) and Messier 108 (bottom) in Ursa Major are two celestial objects that appear to be close to each other but in reality are separated by an immense distance in space.
M97, known as the Owl Nebula, is a planetary nebula located inside our own galaxy at about 2,500 light-years away and has a diameter of about 2 light years. It was discovered by Pierre Méchain in 1781 and it was included in the famous catalogue of Charles Messier as entry 97. Two prominent dark spots inside the nebula give the appearance of an owl’s face.
A planetary nebula is formed by the expanding shell of gases blown off by a dying star at the last stages of its life. The expanding shell is heated by the radiation of the central star (a very faint 16th magnitude star in this case) and it glows mostly in green light of oxygen atoms. The nebula will completely disperse into space over the next several thousand years, while the central star will cool and fade away over the next several billion years.
The estimated age of the Owl Nebula is about 6,000 to 8,000 years.
Galaxy M108, the Surfboard Galaxy, is harder to see in a telescope than M97, because its light is spread out over a larger area. It happens to lie near the same line of sight as M97 but is located at about 45 million light-years away. M108 is an edge-on spiral galaxy, heavily obscured by dust. It was also discovered by Méchain.

Earlier I already posted a picture of starlings and their wonderful plumage (www.flickr.com/photos/115540984@N02/50001279897/in/datepo...). Here is another one, in a different place (Eemnes) with different light (gray weather without sun).
I am still amazed by the fine structures and the color nuances, caused by light refraction. A wonderful bird for sure!
There has been some welcome light rain in Brisbane today. Here are some of the raindrops suspended in a spider web, each producing a refracted image of a hibiscus flower behind them.
When the light reaches the throat of the Brazilian Ruby Hummingbird (male), the green feathers change to golden or to ruby depending on the angle you are looking and the angle the of the light itself.
In these two photos you can see part of the transformation: golden in the first photo and light ruby (something more similar to orange) in the second photo. But I assure to you that the throat really changes to vibrant ruby tone depending of the light and movement of the bird too.
7 fun facts about hummingbirds
1- The indigenous gave very suggestive names to the hummingbirds, which perfectly described these charming birds:
For the "Caraíbas indians", they were the “colibris”, which means “resplendent area”.
The "Tupis" called them “guainumbis”, that is, “sparkling birds”.
For the "Guarani indians", on the other hand, hummingbirds were the “mainumbis”, that is, “those who enchant, next to the flower, with its light and splendor”.
2- Its huge heart, which represents 19 to 22% of the total body weight, facilitates the rapid circulation of blood.
3- In a single day, they are able to ingest nutritious substances up to 8 times their body weight.
4- Some hummingbirds develop average speeds ranging from 30 to 70 km per hour and the vibration of the wings can reach 50 to 70 beats per second.
5- They are the only birds that can literally stand still in the air, take off and land vertically, and even reverse in mid-flight.
6- The spectacular color of hummingbirds originates from the phenomenon of refraction of light, through the microstructure of the feathers. The color changes, observed in the same bird, vary according to the angle of incidence of sunlight or the movement of the body.
7- They say that Igor Sirkorski, who invented the helicopter, based his ideas on the continuous observation of the flight of hummingbirds. However, the helicopter cannot fly upside down. Hummingbirds can.
