1.) What does DPI stand for and what is the difference between a low DPI like 72 and a high DPI like 600?
DPI stands for 'Dots per Inch'. This is used to measure the resolution of an online image when printing.72 dots per inch will take less time to print but is at a lower quality. The printer only prints 72 pixels per square inch and can not usually display the image at its actual size. Higher DPI like 600 will take more ink and take longer to print, but it will be a much higher quality. The printer will print 600 pixels per square inch. The colors will blend more smoothly and the tonality will be better.
2.) What is an aperture and what do the different f stop settings mean?
Aperture is the unit of measurement that defines the size of the opening in the lens of a camera. This can be adjusted to control the amount of light reaching the film or digital sensor. The different F-stop settings are the steps of ratios of the lens's length to the diameter of the pupil of the eye. Its numbers represent a measure of the lens's speed. Each number represents half of the light intensity from the previous number.
3.) What is shutter speed and what difference does it make?
Shutter speed is the length of time that the shutter is open. It can either freeze an object in place or create a blurred image.
4.) What is ISO in photography?
ISO is the sensitivity of the camera to the available light. The lower ISO, the less sensitive the camera is to the light.
I wanted to do something simple for my painting so I chose a beach landscape. To show depth, I am going to do a large palm tree coming up from the bottom of the canvas into the middle. The pictures show my painting process. I started with the sunset and blended the sky. Then I did the clouds that are bad. Then I did the water with sunlight shining on it. I need to add waves and the palm tree to be finished!!
