I joined the Photowalk for Halifax this year. Our leader Glenn Euloth organized the walk which started on the Halifax Commons during the commons 250th anniversary. I met some skaters and bikers at the skatepark who were willing participants for a photo shoot. You can see more photos from the walk on my Flickr page.
In the past I always used AdobeRGB as the colour space for my photos. It worked well when I was printing images at work on a digital press. AdobeRGB is a much wider colour than the output of a digital press. Now I use an Epson 3800 for printing and my favourite paper is Epson Premium Lustre. The Epson 3880 can print colours that do not exist in the AdobeRGB colour gamut. About a year ago I switched to ProPhotoRGB when exporting images from Lightroom for printing so I can use the full colour gamut that is available on the 3880.
This quicktime movie compares the colour gamut of Premium Lustre paper from an Epson 3880 with the AdobeRGB colour gamut. The AdobeRGB is represented in blue. You can see many yellows and teals that the 3880 can print on Premium Lustre that are outside of the AdobeRGB colour gamut.
I wrote an article for the Photographic Society of America about using the ProPhoto colour space in Adobe Photoshop and Lightroom to preserve all the colour that your camera can capture in an image. These are supplemental graphs to show the relationship between the various common colour spaces. As you can see in the graph below ProPhoto is much larger than AdobeRGB and sRGB. If you convert the RAW images from a camera to AdobeRGB before printing you have lost some of the colours that a good quality printer can print. This will limit the colour gamut that you achieve in a print.
I live near Peggys Cove and I often go there to take pictures. I usually go early in the morning or in the evening when the light is better and there are no tourists. Rarely do I get an interesting sky.
On July 2, I was shooting in the garden because there was no wind and clouds were gathering making conditions ideal for pictures of flowers. The sky started to darken and within ten minutes the wind was blowing and the rain was pouring down. It was a startling change. It rained for about 30 minutes but the clouds were very interesting after the downpour. I decided to go to Peggys Cove and it was worth the trip.
Conventional wisdom says you should convert your photos to sRGB for display on the web. This was certainly true in the past. Modern browsers support colour management and if you have tagged your images to embed the colour profile, they will display properly. In Photoshop select embed color profile when saving an image. Lightroom automatically embeds the colour profile when you export images.
Tagged Images – Colour Profile Is Embedded
Each of the following three images is tagged with the colour profile that was used to create the image. The colour is accurately rendered in a modern web browser that supports colour management. If the colour looks similar in the following three images then your browser supports colour management. If the top three images look like the bottom three images where the colour becomes more unsaturated in each image, then your browser does not support colour management.
Untagged Images – Colour Profile Is Not Embedded
The following images are the same files but the colour profile was not embedded. These images are untagged and the browser cannot identify the colour space that was used for the image so the colour is rendered incorrectly. The browser assumes the colour space is sRGB. Note that the last image is in the ProPhoto colour space but it looks very faded when the browser assumes it is sRGB. If the images above look similar to the images below then your browser does not support colour management.
I have been invited by the Ski Patrol to shoot Martock’s annual Slush Cup again this year. This event is a lot of fun for skiers and non-skiers. The Slush Cup starts 1:00 pm on Saturday at Martock near Windsor, Nova Scotia.
The link to the pictures will be posted here after the event. For more information on the Slush Cup check Martock’s web site.

Here are the photos for 2012.
I will be one of the presenters this year at the Digital Imaging for Photographers workshop this year on Saturday March 3rd in the Burke Auditorium at Saint Mary’s University. It is hosted every year by the Photographic Guild of Nova Scotia. All presentations will be from 9:00 am to 4:00 pm. Registration starts at 8:30 am and the cost is $40 per person.
I’ll be be talking about colour management for photographers. Learn how to use Xrite’s ColorChecker passport with Lightroom to make it easy to capture colour accurately. I’ll also be demonstrating some of the new features in Lightroom 4 for printing and soft proofing.
I’m the official event photographer for the Skate the Common Marathon at the Halifax Oval on February 18th and 19th this year. I’ll be there all weekend with my crew taking pictures of all the competitors in each race. We will be printing the photos on site so competitors can buy a souvenir photo to take home with them. One 8×10 photo is $12 or two 5×7 photos are $12. The photos are printed archival Premiun Lustre paper and packed in a crystal clear bag for safe transportation. A portion of the proceeds from each picture will be donated to the Halifax Regional Speed Skating Club to support their programs for skaters.
The Photographic Guild of Nova Scotia is presenting a show at the Viewpoint Gallery. I’m one of the orgnaizers for the show and one of my images will be featured during the show. Everyone is welcome to come to the opening reception on June 2nd and to the artist talk on June 19th. Hope to see you there!
