Understanding Evaluative Metering on Your EOS Camera Photo by Flickr user MiNe By Andrew S. Gibson – the author of Understanding Exposure: Perfect Exposure on Your EOS Camera (currently 36% off at SnapnDeals). Imagine that it is early 1959. Lidar to DEM Introduction Geographic Information Systems (GIS) often store representations of continuous surfaces representing physical properties such as elevation, temperature, water depth, etc., which can be approximated to a reasonable level of accuracy by smooth, single valued functions of the form z=F(x,y). Often such a surface is stored as a regular grid—or raster—of data values. When physically measuring the value of the surface, it is often impossible to collect data for every point on the surface. Instead, scientists collect a sample S of N spot measurements of the form (x,y,z) and reconstruct the continuous surface z=F(x,y) by interpolating the points in S.
Create a Photo-Realistic Orange from Scratch - Photoshop Tutorial Step 1 Create a circle using the ellipse tool. Orange should not have a smooth spherical shape. So we need to make it irregular. Add anchor points as in the figure and create and make the circle irregular. Step 2 15 Tips for Successful Fireworks Photography With the summer coming up and different celebrations you may have the opportunity to photograph some fireworks. If you’re in the USA you have the 4th of July, in Canada July 1st.

Image Scale Math Image Scale Math Educator Guide Audience: EducatorsGrades: 6-8 Image Scaling is an important first step that all astronomers perform in understanding image-type data produced by satellites and telescopes. Micro trends: Graphic design aesthetics We’re not interested in trends for their own sake. For many designers, the very word ‘trend’ is something of a taboo, conjuring up images of blind imitation of whatever’s hot at any given time, rather than encouraging genuine innovation and independent creative thought. Rest assured, you won’t find any of that here.
Photography: How to Take Sharper Pictures Welcome If I had a nickel for every time someone with a new camera blamed the camera itself as the reason why their pictures aren’t coming out as crisp as those seen in photo books, magazines, or even this website, I’d be able to pay someone to write this guide for me. Unfortunately, I don’t. So here I am. The application of remote sensing technology to marine fisheries: an introductory manual A sensor is a device which detects emitted or reflected electromagnetic radiation and converts it to a physical value that can be recorded and processed. Sensor systems may be divided into two major categories: 4.1 Global Acquisition Systems

Ron Herron's "Mamiya 35mm Cameras" Sunny 16 Rule The "Sunny 16" Rule and Other Camera Basics For some of the younger crowd it may seem hard to believe, but until the late 1960s very few photographers used electronic exposure meters. Most relied on experience (or secretly used printed exposure guides). Some photographers (us "Old-Timers") still prefer to work with the old mechanical cameras, and know that it pays to have some of the basics in your head, because the essential photographic facts, formulas and rules can help you get good shots, even when the fanciest of meters fail.
