The Lastolite Ezybalance is a versatile grey card system, which has

many uses for both conventional and digital cameras.

1) ‘Point and Shoot’ Function – typically used in product

photography the point and shoot function ensures photos are

correctly exposed i.e. removes grey tones to give a bright, well

exposed shot. It will also colour correct to give more accurate

colour replication. This function can be used in two ways:

a) In fluorescent light (3500k+), HID, HDI & HMI bulbs

and daylight:

i) Simply set camera to auto.

ii) Frame shot.

iii) Place Ezybalance on object.

iv) Half depress shutter. Ensure Ezybalance

completely fills the view finder.

v) Remove Ezybalance.

vi) Shoot.

b) In tungsten light:

i) Set white balance (refer to camera manual).

ii) Follow instructions above from ii).

Using Ezybalance Sets – follow the ‘point and shoot function’

instructions as above for each of the different grey surfaces. Then

compare all three images on a screen and select the best one.

2) Colour correction (post capture). If you want to adjust

colours accurately when you are short of time while shooting :-

a) Position Ezybalance so that there is no direct light on it

ensuring it is in the same plane as the subject to

camera.

b) Take photo with grey card in shot and then repeat

without the grey card. This would need to be done with

each variation in light conditions, for example, indoors or

outdoors.

c) In photo imaging package Adobe Photoshoptm, select an

area of grey card.

d) Apply Gaussian blur in filters’ section of Adobe

Photoshoptm and deselect.

e) Pick eye dropper and set to 5 by 5 average.

f) Click on to image / adjust / curves

Apply the middle dropper (grey) to the treated part of

the Ezybalance and press ok.

g) In some versions of Adobetm , this action can be saved

and applied to a group of images simultaneously

allowing each setting to be adjusted via batch

processing.

3) White Balance (pre - capture).

For accurate colour rendition, first follow instruction 2a) using either

the grey or the white side of the Ezybalance.

Point the camera so that the viewfinder is filled only with the

Ezybalance. Find the white balance function on your camera. Use

the custom white balance (often shown as symbol)

and follow the camera instructions. Remember to rebalance in

each lighting circumstance.

4) Exposure Control.

Getting a scene like the once above correctly exposed can be

difficult. What do you want to take the exposure of - the sky,

the mountains, or foreground? The Ezybalance will expose the

image accurately.

a) Using the camera’s light meter

Set the aperture of the camera with the Ezybalance

sitting near the principal subject, but without direct

light shining on the card. Fill the screen with the

grey Ezybalance and take a camera reading.

Recompose and set the speed as previously

indicated. Remove the Ezybalance and shoot.

b) Use a light meter to take a reflective reading off the

Ezybalance and then set camera as indicated by the

light meter.

5) The white side can also act as a small reflector.
