Cyanotype
The inventor of the cyanotype is Sir John Herschel. The cyanotype was introduced in 1842. Cyanotypes are created wit potassium ferricyanide and Ferric ammonium citrate. Cyanotype is a photographic printing process that produces a cyan-blue print. Engineers used the process well into the 20th century as a simple and low-cost process to produce copies of drawings, referred to as blue prints. DaguerrotypeThe Daguerrotype was invented by Louis Daguerre and was first introduced in 1839. The Daguerrotype is a picture taken used by iodine-sensitized silver plate and mercury vapor. It was the most used method when it came to taking pictures. It was wildly popular for over 20 years.
The Dog and the owlA lonely owl sitting upon a tree, just pondering life. The owl wants a new friend because he's been alone to feast on field mice. The owl thinks about making a new mice friend. Then he realized that mice are food not friends. The lonely owl spots a dog in the distance far enough where the dog doesn't see him. The owl jumps down to the grass to become friends with the dog. The owl is skeptical because he doesn't know how the dog will react. he sits waiting to see if the dog will approach in a friendly fashion. The dog spotted the owl and chases him barking relentlessly. The dog chases him and the owl spots an old abandoned wear house. The owl runs into there with the dog right on his feathers. The owl was able to manage to fit through the broken wood and slip in the wear house. The dog follows him into the wear house and got his head stuck! the owl fled no where to be seen. The dog is left starving and whimpering for help but no one is near. The dog figures he will die so he prepares himself for the worst. He realizes his life as a stray is hard and this death may be fortunate. The dog has passed but into a better place. All dogs go to heaven, and he went to never starve again. The stray dog with his newly found wings flies into heavens gates. The owl is to never be seen again. As for the dog he is eating squirrels and all the food he wants. All dogs go to heaven.
These three pictures were taken at different apertures and shutter speeds. When changing the aperture the shutter speed automatically adjusts to the aperture. The lower the aperture f/# then the more focus on one specific subject and the blurrier everything else is. The higher the aperture f/# the wider the focus is and other subjects can be in focus as well. The shutter speed fractions get smaller when the f/# gets bigger and visa versa. I noticed this in the picture especially the f/1.8 it is more noticeable that the focus is all the way on the middle box to the right.
DSLR stands for “Digital Single Lens Reflex”.
A DSLR is a digital camera that uses mirrors to direct light from the lens to the viewfinder, Which is a hole on the back of the camera that you look through to see what you are taking a picture of. Exposure
Before taking a Photo, Consider the following
Aperture in a camera
Size of Aperture- Large VS Small Aperture -In photography , aperture is expressed in f-numbers (for example f/5.6). These f-numbers that are known as “f-Stops” are a way of describing the size of the aperture, or how open or closed the aperture is. Apertures
Shutter Speed
For example ¼ means a quarter of a second, while 1/250 means one two hundred and fiftieth of a second or four milliseconds. Rule of thumb for shutter speed The slowest shutter speed for handheld is 1/60. Anything lower then that should either be on a tripod on a straight, solid surface. Any slower handheld shutter speed begins to get motion blur and your photograph may be out of focus. ISO
General rule of thumb
Modes on the DSLR M- Manual Control over aperture and shutter A- Aperture Priority (Focus on the flower and not the background) S- Shutter Priority (Focus of moving objects and captures movement) P- Camera sets shutter speed and aperture How to hold a DSLR
The image above is an camera obscura. A camera obscura is an image carried by light illuminating the image from outside into a dark room. The image is what ever is outside from whats on that side where the light is coming in. The image is flipped but can be set right with a mirror. This helped start the world of photography because it helped grasp an understanding of how light works and how to capture it. In order to make a camera obscura. The time to do this is when the sun is out, then you will also need a dark room. Keep the room entirely dark and make a little hole where light can travel and carry an image through. The light travels into the dark room and projects it onto the wall or what ever is in front of it. What you would want to do it=s cover all windows or any ways light gets in by putting black curtains or black paper anything to completely darken the room. then create a hole where the light can travel right through.
