Camera Tutorial 04: Lenses

In this episode of "Learn to Speak Camera", I give a brief overview of the main types of lenses which most consumer and professional cameras can use. Since compact and bridge cameras are stuck with the lenses they have, some of this does not apply to them. However if you own a compact or bridge camera you may find it informative to learn what you could have access to. I would recommend hiring a DSLR body and a couple of different kinds of lens if you want to get practical experience of the differences. The errata for this episode are posted here: www.facebook.com The properties of lenses are important and intricate topics, which will be visited over the next episodes: Focal Length in episode 5, and Aperture in episode 7. The related topics of Crop Factor, Shutter Speed, and Autofocus will appear in episodes 6, 8 and 14 respectively. Sorry about the jaundiced look - lighting problems! I get this fixed by episode 7.

Digitally Optimised (DG) Filters EX DG filters benefit from Sigma's multi-layer lens coating, developed to counteract the highly reflective characteristic of image sensors. With older style filters, light would reflect off the image sensor, bounce off the lens and filter elements and re-enter the image sensor, creating a ghost image. The multi-layer coating dramatically reduces this effect. In addition to this, an optimum, neutral colour balance is ensured, increasing the white balance accuracy of the digital camera. Wide Multi-Coated Circular PL It reduces the glare and reflections from glass and water and other non-metallic surfaces. It deepens blue skies, and saturates the colors. The Sigma circular PL filter is designed to give best performance with AF Cameras. The Sigma wide multi coated circular polarizing filter is very thin, so it does not cause vignetting with wide-angle lenses. You can monitor the changes at different angles through the viewfinder as you rotate this filter.

This is a great lens for someone starting to build a lens collection. I have had great luck photographing lilies as well as portraits. Macro option makes it a great alternative to a standard lens.

Lens is lightweight but still has good construction.

Macro option can only be turned on at 90 mm this was a little confusing at first.

Great pictures great price.

Traditional Photography Printing


Image : http://www.flickr.com


Printing in the darkroom, is quite different from developing negatives. To do so correctly you need some specialized, although reasonably priced and easily available equipment. To begin this final installment of the Darkroom series I want to start by mentioning the tools, equipment, and chemicals you need to work on your darkroom printing.

The Tools:


Asafe box (a box that has a lightproof seal). The paper comes in many forms such as Resin Coated, Fiber, and Canvas.
Enlarger: An enlarger is the main piece of equipment needed to print from your negatives. The enlarger works by projecting the negative about the photo paper. Each enlarger is fitted with a light bulb, lens, film holder and filter tray, although some enlargers have a built in filter system. Different lenses need to be used depending on the film (i.e. 35mm, medium or large format).
Filters: Filters are used to adjust the contrast and tones of the negative being projected onto the photo paper.
Infrared light: Since you will be using light sensitive material, you need to work in your darkroom using infrared light instead of normal light conditions. Infrared allows you to see, but it does not affect the papers.
Developing trays: Developing trays are needed to contain the chemicals to develop the paper. They vary in size from 8"x10" and up.
Thermometer: You will need a thermometer to ensure that the correct temperature is reached while developing.
 Beakers & Stirrers: As with developing film you will need some beakers and stirrers to prepare the chemicals; stirrers are simply long plastic tools that mix the chemicals.
Bath: A water bath is needed to wash the final print.
Notebook: Printing and working in the darkroom means you have no exit data to help you with exposure times. Instead, you will need a notebook to record your data.
Dodging/Burning tools: These are easily made tools that allow you to control the light hitting certain areas of the paper in the enlarger. I will go through the dodging/burning technique later in next articles.
