My friend Matthew Simmons and I did recently did a photo shoot with an amazing little girl named Desi Robinson. After sending Renee, Desi’s mother, the finished images and talking to her a few days after, something really hit me.

Renee thanked me for asking Desi to do a shoot with Matthew and I, because she had “come so far” since having that experience. After hearing this, I wanted to explore this idea a little more.

I had always believed that it was important to have your portrait made at least once, but I didn’t have any solid, real life examples as to ...ادامه مطلب...

2. ISO

ISO is a measure of how sensitive the sensor of your camera is to light.  The term originated in film photography, where film of different sensitivities could be used depending on the shooting conditions, and it is no different in digital photography. The ISO sensitivity is represented numerically from ISO 100 (low sensitivity) up to ISO 6400 (high sensitivity) and beyond, and controls the amount of light required by the sensor to achieve a given exposure

At ‘low’ sensitivities, more light is required to achieve a given exposure compared to high sensitivities where less light is required to achieve the same exposure.  To understand this, let’s look at two different situations:

Low ISO numbers
If shooting outside, on a bright sunny day there is a lot of available light that will hit the sensor during an exposure, meaning that the sensor does not need to be very sensitive in order to achieve a correct exposure.  Therefore, you could use a low ISO number, such as ISO 100 or 200.  This will give you images of the highest quality, with very little grain (or noise).

Taken at ISO 100, the image does not show signs of noise

(even when looking at the 100% crop (right)

High ISO numbers
If shooting in low light ...

گام اول:
توصیف عکس: شامل شرح موضوع عکس و صحبت از محیط اتفاقی عکس است. اطلاعاتی درباره‌ی عکاس، زمان عکاسی و محیط اجتماعی که عکس از دل آن سربرآورده است. این مرحله مهم است زیرا باعث گردآوری اطلاعاتی است که به درک عکس کمک می‌کند.
