FOOD DUDES!

Photo Analysis Estimator TrainingSeptember 2012

Photo Naming

Photo names are the number on the sticker, followed by a dash and then either a 1 or 2. 1 indicates “initial”; food prior to consumption 2 indicates “final”; tray after child has eaten

Photo Name: 191815-1 Photo Name: 191815-2

Photo Naming

Name the photo as the ID number indicated on the plate with a -1 or -2.

If a photo is duplicated indicate with a (2). Example: 12347675-2(2)

Once files are named, put them into one folder and they will automatically line up in order.

The Reference tray should be named “0-Reference Tray”. This places the tray at the top of the list.

Sorting Photos

Sort photos into 3 folders: 1. Pairs

all photos that have both a before and an after picture

2. Unmatched Photos that are missing either a before or after

picture 3. Unidentifiable Photos that have an ID number, but you cannot

read it (too blurry or partially covered up). Put in as much of the ID number as you can

read with a “-” or “*” to fill in missing numbers

Before/After

Photo Analysis Overview

Following the protocol, compare photos (“before” and “after”) and record the amount of foods consumed on an excel spreadsheet.

We are focusing on milk, 100% juice, fruit, and vegetables

Your estimates are entered into columns on the prepared Excel spreadsheet

Follow the Protocol

Fruits and vegetables – home or school School:

Look for columns labeled with specific food items served through the lunch line

It will be specified on how to measure item If you find a picture with food item not listed on

the spreadsheet or wrong sheet please contact Alyssa.

Home lunch: Combine all fruits into categories of canned,

fresh, dried or juice Combine all vegetables into categories of cooked,

raw, canned, or juice.

Files on your Flash Drive

Spreadsheet Overview

Spreadsheet Details

Important Reminders!

You are recording the amount consumed (photo 1 – photo 2 = consumption) – not the amount

remaining on the plate!

Always round up to the next “measurable” increment. This is the same for fruits and vegetables measured in

pieces.

Record your estimate in numbers only No words or symbols

Do not make changes to the spreadsheet formulas or columns

Completed Spreadsheet

Accuracy is Important

We need >80% inter-rater agreement Salad tends to be the trickiest to estimate Do your best to estimate on tricky trays but do not

assume or label all as a 999 Use the reference tray photo!

We will provide training as necessary to obtain this level of agreement

We will contact you if your agreement to the “truth” is <80%
