Week 3 The Science of Art. In our third week we discussed how to put to use all the science we learned last week into creating artistic photographs.
Week 2: Science vs. Art
In our Week 2 Class we discussed Science vs. Art. All the science behind photography: Shutter speed, aperture settings and ISO Speed.
Week 1 Intro: Digital Photography. The next six weeks will be dedicated to posting class notes for the Adult Education Intro to Digital Photography class I teach. Whenever I teach the class students ask me to send them copies of the slides and the web links I talk about in class. Starting with the session that begins today, I will post the slides right here after each class and you can come to that week’s post to review them, download them or print them. Free!
Welcome to 2017!
It’s a New Year and a time when many people set overreaching goals for themselves that usually fall by the wayside before the month runs out. I learned long ago that I will not lose 50 pounds before Spring; I will not exercise 4 days a week for an hour; I will not squeeze enough money out of my monthly budget to buy that new $1,500 camera. With advanced age, sometimes comes a little wisdom in knowing yourself and realizing you just should not set completely unrealistic goals for yourself. So, I set small, attainable goals. These are the ones you may actually have a chance to fulfill. Let’s talk about some Photographic Goals you can set for this year –and actually attain them.
This is the season of hope and love for humanity. We renew our faith and take stock of our families and the love we share. The memories of this season are captured in our photographs for future generations to admire and reflect upon. It’s a time of sharing family history and of retelling the stories and traditions past. Yes, Photography plays a role in this sharing of memories and traditions, but there is much more to it than that.
Filters cover a wide variety of uses. In the old days of film, filters were used to create effects that would enhance or change the way the film was exposed right in the camera. There were a whole host of filters available for many effects. Today, most of these effects can be created right in your camera, or on in your photo editing software. In fact the software usually refers to these effects as applying a filter. This makes, by and large, the purchase of filters unnecessary.
With a few notable exceptions.
So far we’ve covered shutter speed, depth of field, aperture and the Exposure Triangle. These are the main building blocks of taking the pictures you want with the effects you have in mind. Once you learn these basics and understand your camera well enough to actually take some photographs and be pleased with the results, spend some time and thought finding your photographic style.
Photography, like most forms of art and science has rules. The rules are meant to be your guideposts to creating an aesthetically pleasing image. The rules of composition have been around since long before photography was invented; their origin goes way back to the old masters who first put brush to canvas. We have become “genetically engineered” to expect these rules in our art. However, art being what it always has been, sometimes it’s exciting and daring to break the rules.
The Exposure Triangle consists of Shutter Speed, Aperture and ISO Speed. These topics represent the three variables that create the perfect exposure. These three pieces of the Triangle work together, balancing and compensate for each other. If your camera is in an Auto setting, as one changes, the other two react to keep everything in balance. If you are shooting in manual, you will need to consider the effect changing one of these three settings will have on the other two. Sound complicated? Not really, once you understand how they work together.
ISO Speed was, in the “olden days”, the sensitivity to light of the roll of film you loaded in the camera. Each roll of film had an ISO Speed. The higher the speed, the more sensitive to light the roll of film was. A low speed of 100 was great for bright daylight. 200 was a good general purpose speed for most uses. As you went up in the ISO Speed range, 400 was the typical black and white speed for general use. A Speed of 800 was used for low light conditions.
