Definition of Monochrome for print appraisals



A black and white work fitting from the very dark grey (black) to the very clear grey (white) is a monochrome work with the various shades of grey.

A black and white work toned entirely in a single colour will remain a monochrome work able to stand in the black and white category; such a work can be reproduced in black and white in the catalogue of a salon under FIAP Patronage.

On the other hand a black and white work modified by a partial toning or by the addition of one colour becomes a colour work (polychrome) to stand in the colour category; such a work requires colour reproduction in the catalogue of a salon under FIAP Patronage.

Understanding Colour Calibration


The club owns a Spyder 4 Elite that members can borrow to calibrate their monitors.
The club projector is calibrated using the Spyder.


Why Calibrate?

It’s important to calibrate your monitor so that the colours you see on screen are the same as you will see when your PDI is projected at the club.

There will always be a difference between the image on a laptop screen or monitor and on a projector. This is because the laptop screen/monitor is back-lit whereas the projector screen is reflecting light.

So be aware that some images look better on a monitor than they do projected, and vice versa.

The aim of calibration is to make the colours as close as possible between the two formats.

We advise judges not to view the images on the club’s laptop during a projected appraisal as the colour, brightness and contrast in the image are calibrated to the projector rather than the laptop.

Hints and Tips

Warm-Up Time: Always let your monitor warm up for at least 30min before using the calibrator.

Ambient Light: The light levels in the room will alter the light that is being reflected in your monitor, along with any strong colours in the room so be careful if you are trying to calibrate in a room with bright red walls!

The Spyder has advice on ambient light in it’s help section.

Notification: It’s probably best to select “never” when the Spyder asks if it should notify you when you should re-calibrate your monitor, otherwise you’ll get annoying messages on screen to remind you when to re-caibrate everytime you start up your computer.

It’s a good feature when you own the Spyder yourself, but not when you’ve borrowed it from the club!

PAGB Judging Collection

Competition/appraisal judges and their comments and scores often provoke much debate amongst camera club members.

The PAGB (Photographic Alliance of Great Britain) published a very interesting and helpful collection of articles in an e-newsletter.  The articles give insight into the various aspects of judging and critiqueing images and we encourage all members to read it.
