Guide to Exposure: Aperture, Shutter, ISO, Light

My brother Joel and his wife Lindsey own a small business specializing in salt water aquariums. (Coral Cove LLC). Typically the fish store is very dark with special lighting over the aquariums. Often Joel asks photography advice. Whether it be asking what type of aperture provides the depth of field he is looking for, how to make the shutter speed faster or slower, explaining the use of ISO and what exactly "grain" is, and overall that photography is just a big light game. Oh yes, and my favorite one was when he asked about white balancing... which is not white like he thought, but actually 18% gray. You see? He did not know this, many people do not know all these things. However, this is exactly why I enjoy helping others.

Want To Learn Some Things? Remember I use a Nikon D90 currently, but this is still the useful for all cameras. I am going to teach you a few things starting with the basics of digital camera operation. I want to help as much as possible to help people become better photographers and separate themselves from just snapping a picture.

Exposure is basically the amount of light reaching the sensor. GOOD and CORRECT exposure consists of four main factors which are ISO (sensitivity to light), Aperture (lens opening, also called f/stop), Shutter Speed (how long the sensor is exposed to the light aka the long click), and last but not least... Light (how much light is in the scene).

This all has to do with light!
E = I x T is known as Exposure = Intensity x Time       Aperture x Shutter

See isn't this easy? It all fits together and makes perfect sense! Now lets talk about scales and mess your easy thinking up! Haha just kidding, it's easy peasy. Just be sure to study and memorize the scales. If you dedicate yourself to that then you will be a much better photographer I promise. Lets work on ISO, Shutter, and Aperture scales now...

The ISO scale for the D90 runs from Low to High. I just about always use the lowest ISO possible. Remember, the higher the ISO the more light sensitive (grainy/noisy). The lower the ISO the less light sensitive (clear/clean). ISO are as follows:
Low (100), 200, 400, 800, 1600, 3200, High (6400)

Aperture (f/stop) is the physical opening of the lens. The more open (f/5.6) the aperture the more shallow the depth of field (blur) in the image. The more closed down (f/22) the aperture, the more full the depth of field (sharp) in the image. Stops double or halve the exposure... for example: f/5.6 is twice as large as f/8 ( + one stop) and F/22 is one half the size of F/16 (- one stop)... Full f/stops are as follows:
1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45, 64, 90

Shutter Speeds are the amount of time that the sensor is exposed to light. You know, the length of the click! Stops double or halve exposures on this camera setting also! 1/60 is twice as much exposure as 1/125 (+1stop)1/500 is one half as much exposure as 1/250 (- 1 stop)Your Camera will have 1/3 and 1/2 stop shutter adjustments. The numbers indicated are actually fractions, for example: 60 is 1/60th of a second and 30" is 30 actual seconds. Bulb setting is a manual setting where YOU hold the shutter as long as you want. Full Shutter Speed Scale are as follows:
30”, 15”, 8”, 4”, 2”, 1”, 2, 4, 8, 15, 30, 60, 125, 250, 500, 1000, 2000, 4000, 8000

Sunflower Field Mini Sessions 

It just so happened that one day I turned left out of my plat instead of right... I never go this way but today was different. My son, Connor, and I noticed there were thousands of gorgeous yellow sunflowers in a field blooming. There is honestly no better way to start the fall season. I decided to grab my camera and start photographing some wonderful little mini sessions.

❤  Equipment & Settings
  • Nikon camera 
  • Images are captured in RAW 
  • ISO settings were 100-400
  • Lenses 50mm & a 18-105mm


Photographed over several days during Golden Hour. All images were captured with the natural light. First day we photographed Connor at sunrise and sunset. Second day we photographed Julie at sunrise. The goal was to capture the dramatic and endless depth of sky. The sunrise and sunset coloring of the sky against the warmth of Autumn are some of my favorites.
 
Clothing choices for this session was inspired to emphasize cool color tones against the warm color tones. Also wanted texture to offer a cozy sense of Autumn season upon us. The light leaks in images were welcome and playing with depth of field was pure joy!


These four images are just a few favorites. We enjoyed the mornings with yummy pancakes. Julie coming over was an extra treat of quality time. I am thankful for these beautiful blooms - it is not very common to see fields of sunflowers, let alone to have them so close to home.
To stop the rushes of the day and be part of something beautiful is  cherished. These images represented beauty life has to offer. It was the choice to stop and take a moment to feel what something in nature has to offer.

MORE Levitation Photography!!

Lately we have been working on a ton of Levitation Photography and Photo Manipulations. We have made several tutorials for people to learn the basics of levitation photography.



Comment below which levitation image is your favorite and we will make a tutorial showing step by step how the image was achieved.
