Practical LAB

Something strange.....I have just been comparing the canned icc profiles of the Epson SC-P900 and the much older Pro4000 (20 years) Looks like my old 4000 was a better beast than the latest technology. The faded representation is the Pro4000. The D Max is far better in the 4000. The better D Max is what we are all chasing, and it should be getting better not worse.

Next LAB tutorial scheduled for the 24th of June. Learn how to use the most powerful colour space for colour correction and production. Complexity made simple. www.robhackman.com Scroll to the bottom of the home page for bookings and course module information.

Firstly, welcome to the new people who have joined the group. I hope you find time here benefitial and a good space to discuss colour and the use of LAB. Before starting in LAB you need to set up your desk space. I have also made up my own quick key command for quickly converting from RGB to LAB which I suggest you do the same because once you start to see the power and simplicity of using LAB you will be converting all your images to LAB to colour correct. So here is the very first part of the lesson that I run for my courses. It makes no perceptual difference to do these steps and at first they seem counter intuitive but they are how LAB practitioners work so to keep us all on the 'same page' I strongly suggest you set up as follows. Over time this slightly 'upside down' approach will make complete sense and become second nature. So lets dive in.....oh also, make sure your Rendering Intent (Edit, Colour Settings int he drop down menu) is set to Relative Colourmetric...unless you have a specific reason for using Perceptual (which is a whole other discussion).
