The Golden ratio

Divine Composition With Fibonacci’s Ratio

Also known as the Golden Mean, Phi, or Divine Proportion, this law was made famous by Leonardo Fibonacci around 1200 A.D. He noticed that there was an absolute ratio that appears often throughout nature, a sort of design that is universally efficient in living things and pleasing to the human eye. Hence, the “divine proportion” nickname.

Since the Renaissance, artists and architects have designed their work to approximate this ratio of 1:1.618. It’s found all over the Parthenon, in famous works of art like the Mona Lisa and the Last Supper, and it’s still used today. The divine proportion has been used by companies like Apple to design products, it’s said to have been used by Twitter to create their new profile page, and has been used by major companies all over the world to design logos. It’s not talked about in most photography circles because it’s a somewhat advanced method of composition and can be confusing to a lot of people. It’s so much easier to just talk about the “rule of thirds” because it’s exact, precise and easy to follow.

This ratio can be used in many ways to compose a photograph. Lightroom 3 even has a golden ratio overlay option when you go to crop on image. This way, you can line up a grid of the golden ratio to coincide with lines or points of interest in your photograph. At this point, you may be quite confused. If you are, please take a few moments to watch any one (or all) of these videos that seek to explain this ratio. Taken from digital photography.com

Hopefully, this article has shed some light on a somewhat mysterious subject in the world of photography. Fibonacci’s Ratio is a powerful tool for composing your photographs, and it shouldn’t be dismissed as a minor difference from the rule of thirds. While the grids look similar, using Phi can sometimes mean the difference between a photo that just clicks, and one that doesn’t quite feel right. I’m certainly not saying that the rule of thirds doesn’t have a place in photography, but Phi is a far superior and much more intelligent and historically proven method for composing a scene.

Making Cyanotype Prints 

Making Cyanotype Prints 

A few days before the new year Lens Culture featured the work of an artist, Lindsey  Beal who using her smartphone made use of a early 19th century technique known as the Cyanotype process.

 How to  make your own Cyanotype Prints ?   

  Article is from Freestyle Supplies web site 12/30/2014 

"Cyanotype is a contact print process and you will need a negative the same size as the size of the print you want. A cyanotype with a blue image on a white background is obtained using a negative transparency. In order to obtain a pale white image on a blue background, a positive transparency must be used.

Cyanotypes are created with a simple solution of ferric ammonium citrate and potassium ferricyanide. If you don't want to find your own chemicals, Freestyle carries an excellent all-in-one kit for you.

The cyanotype emulsion is sensitive to ultraviolet light. Therefore either sunlight or another UV light source must be used for exposure. For consistent results, a UV light box is recommended. Freestyle offers an excellent, hand made version that is perfect for this application. Another option is to use a General Electric 275-300 watt sunlamp, but the light gets extremely hot, so keep your material at least 12-18 inches away from the bulb. It may be tempting to use a piece of glass to keep your negative down, but bear in mind that glass does not transmit UV light well.

Besides all the chemicals and a UV light source, Freestyle Advisory Board Member Jill Enfield recommends the following:

Apron, gloves, cheesecloth, hair dryer, clothesline, mask, clothespins, mixing rod, contact print frame, newspaper, cups and bows, pencils, distilled water, plastic spoons, drafting tape, plexiglas, drying screen/blotter book, scale, fan, tongs, glass and wax paper."
