What is Tilt Shift Photography ?�
This is the realm of photography that involves tilting the lens with respect to the picture plain and taking photos in that configuration. “Tilt-shift” actually has two movements: the rotation of the lens, called Tilt and movement of the lens parallel to the image plane, the Shift.

 On a regular camera, the image plane, lens plane, and object plane are parallel, and objects in sharp focus are all at the same distance from the camera.. When the lens plane is tilted relative to the image plane, the Point …

The angle-of-view is how wide an area is seen by a given lens.
Angle-of-view is determined by two factors, the focal length of the lens, and the area of light sensitive material used to capture your image. That means, when your lens becomes longer the angle of view is reducing and the final image will contain lesser area of the image plain. This is what gives the effect of zooming in or enlarging what is being seen to a particular area of interest.

As a general case when the focal length …

Let us take it from the basics of what super macro photography is. Super macro is referred to the photographing of subjects at a ratio of more than 1:1. Normal macro is when we shoot at 1:1 magnification ratio, that is the 1mm of the subject is produced on the sensor as 1mm. Now super macro photography is when we represent 1mm on the subject as more than 1mm on the sensor.

Lets get some things cleared first, the larger the aperture the smaller the depth of field that means the smaller the f stop the smaller the depth of field.  I repeat in bold
Large aperture = Small DOF
Small Fstop  = Small DOF
So what does that mean when u are using say 2.8 Fstop on your macro lens the depth that will be in focus will be less than when using say 4. I would like to look at depth of field as the volume in focus. Remember that the DOF extends …

Today most camera’s have the capacity to focus, that is previously there were cameras that had an infinite preset focus but today any camera selling above 50- 60$ have an auto focus system. Auto focus is a system where the focusing lens arrangement is repositioned to attain a focus image, by the camera itself to get a sharp image.�

The above image shows the standard auto focusing system in a very simplified diagram. This is the system that most DSLRs implement. Such a system is expensive dues to …

Have you been wondering what this Bokeh, that most pro’s talk about, is? It is actually the misspelling of a Japanese word if you take it in a literary sense. The real spelling is Boke and its a Japanese word meaning Fuzzy. OK don’t wonder where your friends learned Japanese from. Photography has a lot to do with Japan and there are a lot of Japanese pro’s this word was commonly used by them to explain the fuzzy areas and its quality. Now an English writer writing for an English …

Monopods are devices used by photographers to stabilize the camera. When shooting in low light condition the cameras shutter needs to be kept open for a longer period of time. When this period of time is long enough for motion to happen the motion will come on the photo thus taken. This motion some times is a useful element in the photograph but mostly it is unwanted. This motion is referred to as blur. The motion can be due to two reasons, one being that the people or object being …

You must have seen the flower like contraption fixed in front of many telephoto lenses. Sometimes, u find them on normal lenses also; what do they do ? If you have had the chance to see a professional movie camera at work, you would have seen a device like an elephants ear fixed to the front of the camera; these are called matte boxes.

The basic purpose of these devices are to prevent glare and lens flares. Now, coming to lens hoods, again, there are different variants. The …
