Photography vs Snapshot


photo by Elizabeth Photog


A snapshot is popularly defined as a photograph that is "shot" spontaneously and quickly, most often without artistic or journalistic intent. Snapshots are commonly considered to be technically "imperfect" or amateurish—out of focus or poorly framed or composed. Common snapshot subjects include the events of everyday life, such as birthday parties and other celebrations, sunsets, children playing, group photos, pets, tourist attractions.

10 Silly Mistakes Photographers Make

1. Shooting without a battery

Well, you cannot really shoot without a battery in your camera. But you definitely can head out without a battery in your camera. Things like these happen in a hurry when you are traveling to new places and you have too many other things to attend to. The days of AA batteries are over and you may find yourself helpless if you went hiking to some remote place without all your gear.

Always shoot a test photo before you head out!

The Exposure Triangle




Photography is about seeking for the perfect light
Without light we have no photograph.
There is only one shoot of a theme that's perfect.
All the others have problems....
They may be overexposed (too bright) or underexposed (too dark),they may be blury or may be with a lot of digital noise.

Understanding the f-stops (of your lens)





On every lens there are some letters and some numbers...
One of them is written in a way like 1:1.8
The number 1.8 is the max f-stop your lens can open
The minimum the number the better the lens
This number shows how much the blades in your lens can open.
As you understand 1:1.4>1:1.8>1:2.8>1:3.5>1:5.6
So a lens that goes to 1.4 can manage more light than a lens that goes to 3.5
That means that you can keep ISO number lower in order to avoid digital noise.
Except that the bokeh you can get at 1.8 is much better than the bokeh at 5.6 as you can isolate the subject from the background.

Reverse Lens Macro Technique



The concept goes like this...
You get a cheap lens like the 18-55mm and you reverse it...Yes you hold it the other way in front of your's camera sensor. The technique really works great if you give it a try and the good news is
that you do not need expensive gear to make beautiful macro shots.

Basically, reverse mounting a lens moves the lens farther away from the camera,
giving it the ability to focus at closer distances,
which has a similar effect as using a set of extension tubes.
Both ends of the lens are not made equally.

High-dynamic-range imaging (HDR)


                         HDR                           Non  HDR

High-dynamic-range imaging (HDR) is a technique used in imaging and photography to reproduce a greater dynamic range of luminosity.
It is a post-processing task of taking either one image or a series of images, combining them, and adjusting the contrast ratios to do things that are virtually impossible with a single aperture and shutter speed.
An HDR image is commonly made by taking three photos of the same scene, each at different shutter speeds. The result is a bright, medium, and dark photo, based on the amount of light that got through the lens.
A software process then combines all the photos to bring details to the shadows and highlights both. This helps to achieve the same task in the final photograph that the human eye can accomplish on the scene.
