When choosing a tripod it is important to consider many aspects such as weight, portability and durability. But it is also important to consider which tripod head would work best for you. When it comes to tripod heads they come in different styles to accommodate diverse situations. Some tripod heads are better suited to steadily hold a large camera in place for architecture or night time photography, while others are designed to provide smooth movement for sports photography or video shooting.

Any serious photographer should own a tripod. Tripods provide needed stability (especially for longer zoom lens shots) as well as fixed shooting point for slow shutter speeds and panorama images. A tripod is an excellent companion for numerous shooting situations such as sports, fireworks, macro, time-lapse, studio and many others. Tripods significantly reduce the effect of camera movement and improve sharpness of long exposure photos. Continue Reading
Lens manufacturers often have different names for similar functions. This is usually done because each brand trademarks their terms. While this is beneficial for their marketing strategies it can get very confusing for the rest of us. When choosing and comparing lenses from different manufacturers it can get hectic trying to figure out what each term means and the name of the same function on a different brand. People new to photography can quickly get confused by all different letters in the name of a lens (e.g. EF 100mm f/2.8L Macro IS USM or AF-S DX Nikkor 35mm f/1.8G). To ease this burden I have done extensive research and piled up this quick reference guide for lens terminology. Continue Reading
We work hard on creating our photographs, so obviously we want to save all of our work. With the latest high megapixel count digital cameras a task of storing this data becomes a real issue. And losing your work can be a real nightmare scenario. Today, I am going to discuss different data storage options and their best implementations. After all we all want our work to be preserved and when the rest of the work is done, data storage is a true final frontier.
There are several ways you can store your data. Each storage option has its own flaws and benefits. However, there is no one fail proof way to store your images, so consider implementing several of these options. Redundancy is the key to any data storage solution and the more copies you have, the better you will sleep at night. Continue Reading
An autofocus (AF) is an optical system that uses an array of sensors and lens motor to calculate correct distance between subject and camera and adjusts the focus accordingly. AF sensors and algorithms have become so advanced over the years that most people don’t even bother learning how they work, as long as it does. However, there are several common situations where camera’s AF might have a hard time focusing accurately and that’s when your knowledge and understanding can come in handy.
EXIF (Exchangeable Image File) is a format embedded into images produces by all digital cameras. EXIF data contains all information about the setting used to take an image. When you capture a digital image the camera automatically records all information it knows about this image and saves it as EXIF data. This is done regardless of which shooting mode you are in, whether it is Auto, Manual or anything in between. EXIF information includes camera make and model, date, shutter speed, aperture settings, ISO setting, focal length at which the image was shot and much more. Some cameras and smart phones that have GPS receiver can even record exact position at which the photo was captured (if GPS function is enabled). When images are saved to computer all this data is transferred as a part of an image. Continue Reading
White balance (color balance) is one of the easiest ways you can improve the quality of your photos. The concept of white balance may seem complicated, especially with all the theory behind it, but it’s really not. Essentially the colors of images need to be balanced because different light sources cast different color spectrum. White balance is a process that changes the entire color mixture, effectively performing a correction of color. Shooting a scene with a light bulb will make the overall image more orange while shooting a scene with blue sky might make the overall image seem bluish. Correct white balance will compensate for these colors and adjust the image accordingly. Our eyes are excellent at distinguishing different color casts and our brains adjust it without us even realizing it. But digital cameras use algorithms to do it and often they cannot reproduce “real” colors especially if a neutral color is missing. Continue Reading
Camera lenses are one of the most important ingredients in a photography formula. Understanding the differences between lenses can greatly improve your photographic performance. Choosing the right lens can open up a lot of artistic opportunities, while getting wrong lens for the job can greatly limit your capabilities. Choosing the correct lens for job can be quite complicated because each selection can open up a set of trade-offs between cost, image quality, lens speed, size, weight, build and reliability.

A memory card (sometimes called flash card) is an electronic storage device which has no moving parts. Because this device operates electronically, rather than mechanically, it is more robust, smaller and less energy consuming than traditional hard drives. This type of memory is often called Solid State memory and it usually has much faster transfer rates than Hard Disk drives. Flash memory cards can be found in practically any gadget that requires some sort of memory storage.
