& Composition

Basic Formula for Photography

Basic Camera Concepts

– Exposures: It takes a certain amount of light for a certain amount of time to capture an image.

– You can adjust the amount of light required (ISO-Film Speed)

– You can adjust the amount of light let in (Aperture)

– You can adjust the amount of time (Shutter)

– All of these adjustments are directly related, and will have a direct effect on each other.

Photography Basics

Think of the formula as a Bucket, Pipeline, and Valve Combination.

ISO Aperture Shutter Speed

ISO settings/changing

ISO is the Film Speed (or the size of the bucket)

In other words, it determines how much light is required to make a picture show up on the film/processor

Concept: A larger bucket takes more water to fill

ISO film speeds generally range from 100 - 6400

The higher the ISO number:– The more sensitive the film– The less light is required to expose the image– The higher the “grain”

The numbers are proportionate. ISO 100 requires twice (2x) the light as ISO 200

ISO settings/changing cont’d

High ISO “Grain”

Although we have a very high quality camera, we need to be aware of “grain” while using high ISO settings

Try to use the lowest ISO setting possible to get the highest quality results.

How to set ISO on the D200

How to set ISO on the D200:

Auto Mode - Go to the Menu Manual Mode- Hold the ISO button,

and spin the rear dial

All About Aperture

Aperture is the size of the opening in the camera lens

Aperture controls the amount of light coming into the camera

Think of it as a “pipeline for light”– The larger the pipeline…the more light can

come in.

All About Aperture

Larger Aperture settings will require lower ISO and higher Shutter speeds.

Smaller Aperture settings will require higher ISO and lower Shutter speeds.

Uses: Larger Aperture settings allow for higher shutter

speeds Smaller Aperture settings allow for more depth of

field.

All About Aperture

Aperture settings are referred to as: “F stops”– F5.6, F8, F2.8, F16, F22, etc….– Larger numbers equal smaller openings.– The F# is actually 1/f

Aperture settings are proportional. F8 is 2x the size of F16.

Depth of field concept: Fire Hose vs. Straw

Aperture Illustration

All About Shutter Speed

Shutter speed is how fast the shutter stays open to capture the image.

Shutter Speed is the “valve” – the longer it stays open, the more light can come through the pipeline and into the bucket.

Higher shutter speeds “freeze” movement Lower shutter speeds add “blurr” effect

Shutter speeds listed as:125, 250, 500,etc Actual is: 1/125th, 1/250th of 1 second

All About Shutter Speed

In the aircraft, you will need a minimum of 1/250 shutter speed to eliminate vibration and movement from the airplane, 1/500 is optimal if possible.

Try to balance shutter speed needs with ISO and aperture settings.

All About Shutter Speed

High vs. Low Shutter Speed

Priority for Settings

More Important– Shutter Speed– Aperture– ISO

Less Important

It is better to sacrifice ISO settings to keep aperture and speed settings up

Composition/Aiming

Focus on the subject “Fill the Frame” – use zoom and

position to crop

Composition/Aiming

You will typically be farther away from the subject than you need to be. Ask the pilot to fly closer if necessary to get the shot.

The ideal angle to the ground is 45 degrees. – 1,000’ AGL, and 1,000’ from target

Under/Over Exposure

Under Exposed Over Exposed

Examples of Under/Over Exposure

Correcting Exposure Issues

Aim the camera at the subject Use the Pre-Focus Metering to lock in

settings Remember: The camera is a

computerized machine…it will do EXACTLY what you tell it to do.

Exposure Correction

Examples of Under/Over Exposure correction by proper aiming and metering

Things to remember about exposure issues:– Photoshop can’t fix bad shots– Color and definition are lost at both

extremes– Some images can be salvaged, but the

image quality will be sacrificed– It’s much easier to get a good shot than

to fix a bad one– It’s ok to go back and reshoot

Reducing Glare with Polarizing Filters

Notice the difference in the glare on the water. The polarizing filter “cuts through” the glare, and creates good color and definition

Without Filter With Filter

Additional Exposure/Glare Techniques

Make sure the horizon is above the top of the frame. – Haze and glare are more likely to occur at

horizontal angles Get up close to your subject

– The more haze between you and the subject, the worse the photo will be.

Use the “glare hood”– Prevents “flare” and “stray light” from

affecting lens glass

Lens Hood Warning

Warning!!!!! Make sure the lens hood is

“snapped” in place The lens hood can be pulled off the

camera by the wind Keep the camera inside the aircraft

Technique Review

Aim at the target Fill the frame Get up on it 45 degree angle No horizon Shoot “down light” if possible Review photos BEFORE you RTB

If your pictures are very “white” and bright, what should you do?

Camera Functions

& Setup

Formatting vs Deleting

Works the same way as your PC

Formatting the CF card resets the file numbering system and reduces the chances of a file error.

Deleting the images simply erases them. The file numbering system does not reset.

Auto-Focus Modes

There are 3 Auto Focus modes: Servo, AF, M– Servo mode provides constantly variable

focusing

– AF mode allows you to temporarily “lock” the focal distance during the “pre-focus”

– Manual mode – the name says it all…

Shutter Modes

There are 5 Shutter modes: S, CL, CH, Clock, Mup

– Single Shot – Works like a semi auto gun– Continuous Low – Full auto @ 2.5 fps– Cont. High – (Rambo Mode) Full auto @

6 fps– Clock – For taking pics of yourself– Mirror Up – Night photos

Shooting Modes

There are 4 shooting modes: P, S, A, M– Program Mode – (Dummy Mode)

Everything done for you– Shutter Priority – Mandated Shutter

Speeds– Aperture Priority – Mandated Aperture

Size– Manual – You set everything on your

own

Issues with Program Mode

A few issues with P mode:– Factory Settings may not be ideal for

our missions• Color• Saturation• Sharpness• Contrast

Image Size/Quality

File Formats : JPEG, RAW– JPEG is the standard file format for

images– RAW is the file format for Nikon, Canon,

etc• RAW images are significantly higher quality

– Thus, the file sizes are substantially larger

• RAW file formats can only be read by special software

Image Compression

Image Compression helps reduce file size

– RAW- No compression– JPEG Fine – 1:4 – JPEG Normal – 1:8– JPEG Basic – 1:16 Lower Quality

Higher Quality

Image Size

There are 3 size formats– Large 3,872 x 2,592 (10 mp)– Medium 2,896 x 1,944 (5.6 mp)– Small 1,936 x 1,296 (2.5 mp)

Larger image sizes can be magnified with more detail.

Smaller image sizes allow for ease of transfer, and more space on CF card

GPS Connectivity

Connect the GPS and make sure the GPS Indicator is SOLID

A SOLID light means you have a SOLID Connection

GPS Placement

The GPS needs to be able to “see the sky” If not, you may still get a “GPS” signal on

the camera, but you may not get any coordinates from the GPS

The front dash and rear baggage area work well

The GPS indicator on the camera only verifies that there is a connection. It does not guarantee that any data was collected.

indicate?

Skill & Proficiency

Skill Development &

Proficiency Management

Developing Skills

Cone Drills– Line up cones– Place in + configuration– Drive around– Take photos on the move

The cone drill develops skill for:– Movement / Vibration– Cardinal directions– Turns around a point– Framing / Composition– Peripheral vision in viewfinder

Lining up the shot

vs.

Use the cones to train the eye to “line up” the shot

Turn around a point

Use single cones to demonstrate radio towers

On Foot

You can also do it on foot– Make sure someone is there to keep you from

tripping

Proficiency

There are lots of people and things to take pictures of around your home to stay proficient.
