Canons Auto Lighting Optimiser Demystified

One of the more obscure camera questions I occasionally field on my workshops from participants who shoot Canon is ‘what is Canons Auto Lighting Optimiser and should I be using it?’ I received this exact question this morning via email from a Canon user who just received their new camera and wanted to understand how this feature works.

First, some history on the Auto Lighting Optimiser (ALO). ALO was originally introduced as a feature on the EOS 450D DSLR in 2008. It has since found its way onto all current Canon EOS DSLR cameras, from Canon’s most basic  entry-level DSLR to the professional EOS-1D X MKII (it was never included in the 1DS MKIII).Canon ALOALO is designed to even out contrast by selectively adjusting areas of the image. It is by definition most useful when using flash or with backlit subjects as it can detect faces in the frame and brighten those areas to achieve a better result. In a nutshell, the aim of ALO is to provide in-camera processing that will improve the look of your images. Those of you paying attention will have already figured out that it applies to jpeg files because it is working on in camera processing.

ALO analyses contrast in captured images and modifies both shadows and highlights via tone curve adjustments to minimise loss of detail in high contrast light conditions. There are three levels of setting strength in the current EOS 1DX MKII (low, medium and high) as well as the ability to turn the setting off. The levels can be used at any ISO speed setting.

The first thing you should know about ALO is where it is located in your cameras menu. ALO is found in the jpeg quality menu. This tells us that this setting applies to jpegs (not RAW files). If you shoot RAW then you can pretty much ignore ALO; with the caveat that it can be applied in post-production if you implement Canon’s Digital Photo Professional Software. If you are using Canon’s Digital Photo Professional workflow software (I honestly don’t know anyone who does), ALO can be applied to RAW images taken on compatible cameras during the post-processing workflow. This cannot be accomplished in Adobe Lightroom. Is this worth doing? Personally, I don’t think the benefit is worth the extra step (I would rather use a filter to tame the scene contrast in camera), but your mileage might vary.

When you select a Quality setting that results in a JPEG image file (have I mentioned you really should be shooting RAW?), ALO tries to enhance your photo while it’s processing the picture in camera. Unlike Highlight Tone Priority, which concentrates on preserving highlight detail only, Auto Lighting Optimizer adjusts both shadows and highlights to try and improve the final image tonality. This ‘could’ be useful if you are shooting jpegs in high contrast lighting and have no intention of doing post production work at a later date.

To sum up: If you shoot RAW (as I do) then you can ignore the ALO setting and just leave it off. If you insist on shooting jpeg then you should experiment with ALO to see what benefit it can yield to your jpeg files in certain high contrast lighting situations.

 

Lofoten Island Winter Workshop Report 2016

In March this year I led a new winter landscape workshop to the Lofoten Islands in Norway with long time good friend and fellow landscape photographer Martyn Lucas. If you are unfamiliar with Lofoten let me assure you that The landscape of these islands is really quite something to behold. Precipitous and ominous peaks that rise straight out of the ocean loom over small fishing villages that comprise of bright red houses lining the shorelines. With a dusting of fresh snow and arctic winter light the entire scene is akin to a fairy tail location and subsequently the photographic opportunities can be truly superb.Lofoten-4779-EditThis workshop was a for a small group of just six experienced landscape and nature photographers. We based ourselves primarily in the small town of Reine and made daily excursions to various locations around the Island for photography. Lofoten has become quite the hot spot for photography in the last few years (some are calling Lofoten the new Iceland) and although we did encounter a few other photographers during one of of our early morning sessions near town (where the above photograph was taken), we primarily had the place to to ourselves. It has been my experience in ‘hot spot’ locations such as Iceland and Lofoten that it is not too difficult to get away from other groups if you travel with someone who knows the terrain and have an experienced guide with you. Both Iceland and Lofoten have a number of iconic locations that everyone visits and photographs. However, both also have a vast number of excellent off the beaten track locations that are rarely visited and even less rarely photographed. On the whole, we preferred to spend the majority of our time in these less visited areas as the opportunity for unique photographs is greatly improved and you don’t have to fight for tripod space.Lofoten-4519-EditLike much of the Arctic, photography in Lofoten in winter is heavily weather dependant. It is entirely possible to be socked in for days with heavy cloud and bad weather in this part of the world (a risk you have to be prepared to accept when you venture so far north in winter). Its common on this sort of trip to loose at least one or two days to bad weather – its par for the course. Fortunately, we had very good weather and light for most of our trip with only a little rain on a couple of occasions. Being so mountainous and surrounded by ocean Lofoten is prone to highly variable weather; which can be both a boon and bane for photographers. The ideal scenario is a dusting of fresh snow with cold temperatures and golden light. We were fortunate to experience this on several occasions. We also had some really lovely cloud during the workshop that made for some wonderfully moody and evocative images.Lofoten-4536-EditDuring our workshop we also experienced and photographed the Aurora Borealis (northern lights). Lofoten is blessed with fantastic mountains that rise almost vertically straight out of the ocean and that make for a superb back drop for the Aurora. As is always the case with Aurora photography the real key to getting interesting photographs is to try and include some sort of foreground and background elements (in this case I chose a small section of partially submerged rocks as my foreground). There is a temptation to focus entirely on the Aurora itself when photographing the northern lights and it is easy to be seduced by the color and activity alone. The solution is to try and photograph the lights in the context of the environment around you. Much like wildlife, where the key is to place the animal in context; you need to put the Aurora into context with its surroundings.Lofoten-0431-EditBeing surrounded by water Lofoten offers  great opportunities for seascape photography at just about every turn and we took advantage of this by visiting and photographing many different beaches and areas of coastline. Much of the coastline is rocky or dotted with large boulders (JCB’s – Otherwise known as Joe Cornish Boulders) which provides limitless opportunities for foreground interest. Many of the beaches are also very accessible and only a short walk from car parks or pull off areas. We spent quite a lot time exploring and photographing various areas of coastline and some really interesting photographs resulted. In the right conditions, Lofoten in winter also has the added benefit of snow down to sea level for even more interest.Lofoten-4973-EditIt is worth noting that Lofoten isn’t just about landscape photography. On our last day we made the decision to mix things up and took a private charter boat out to photograph White-Tailed Sea Eagles fishing off the coastline. This proved a worthwhile gamble with a couple of hours of really wonderful eagle photography in occasional light snowfall. Photographing fishing sea eagles from boat in winter in the Arctic is a lot of fun. We were able to get quite close to some of the eagles (so close my 300mm F2.8L IS MKII was occasionally too much lens and I had to switch out to the 70-200mm F2.8L IS MKII. I did not yet have a production version of the new Canon EOS 1DX MKII so all photographs were taken on the original Canon EOS 1DX. I have subsequently sold both my original Canon EOS 1DX bodies and migrated completely to the newer MKII.Lofoten-1554-EditEdit: As a side note: I have now spent three weeks in the field with the new Canon EOS 1DX MKII in the South Island of New Zealand. In my experience to date I have already found the auto focus on the new MKII to be a significant improvement over the original (and thats a significant statement) – particularly in back light and low light situations. I was photographing the rare and endangered Yellow-eyed penguins in the South Island in very difficult back light and found the camera continually nailed focus in this situation. Back lit subjects are one of the hardest tests for any auto focus system. The system also performed flawlessly for Bullers Mollymawk Albatross in Miflord Sound. More to come on the new EOS 1DX MKII in a future post including my thoughts on the high ISO capabilities.

Visiting Lofoten in Winter also provides an opportunity for cultural photography. At this time of year the cod are being fished around the Islands; they are then processed and hung to dry on the many cod racks dotted around the Islands (yes, you can smell them long before you see them). Every part of the cod is used and even the heads are hung to dry. I am personally not a street or cultural photographer but the process is nevertheless interesting to watch and photograph.

To those of you who have already contacted me asking about a future workshop to Lofoten in 2017 or 2018:  At this stage I will not be running a future trip to Lofoten (due to other commitments of which I will have more to say in the next few days). I would however, like to thank Martyn for his assistance in guiding the group to some fantastic locations and to all who participated and contributed to this workshop. We were blessed with some wonderful conditions for photography and some really remarkable images resulted from our experience and time in Lofoten. Small, intimate groups for this sort of landscape photography workshop are the ideal way to ensure you capture the best possible photographs.

 

Guest Photographer: John Hurshman ‘Hot and Cold’

Following on from my recent guest photographer post from Kevin Horsefield – Iceland the Frozen North, I want to share a short interview and photographs from John Hurshman who recently accompanied me on my Iceland Frozen North 2016 Workshop. I have had the pleasure of travelling and photographing with John now in both Iceland and Namibia and am looking forward to sharing an expedition to Svalbard with him for Polar Bears next year. Please enjoy the interview by Digital Transitions and photographs from our most recent Iceland and Namibia trips.

DigitalEditors Note: While most of our clients are professional photographers deriving their income from their craft, we also have many clients for whom photography is a passion, but not a source of profit. We thought we’d share the work of one such client, John Hurshman, who has recently traveled to both Namibia and Iceland. This combination struck us as especially interesting as it highlights the robust nature of Phase One digital backs – from the heat of the African Desert to the cold of the Icelandic winter. We interviewed John by email, with some editing for length, clarity, and focus.1_IcelandDT: What is your relationship to the art and practice of photography?

John: I am a retired corporate CEO who has been involved in photography for 35+ years. While early on, I had work published by National Geographic Books, Audubon Calendar and National Wildlife Magazine, the demands of family, career and business travel precluded much time for photography. It is only since I retired in 2012 that I have had the time to re-establish my involvement in photography. Much of photo time is spent in the environs of Charleston SC, my adopted home. Additionally, I now have the time for photo tours/workshops… Namibia in 2014, Iceland in 2016 and Polar Bear of Svalbard scheduled for 2017.2_Iceland

DT: Have you switched to Phase One or do you use it alongside other cameras?

John: I haven’t really “switched” to Phase One, but use is in conjunction with another system… most recently Fujifilm X-PRO2 mirrorless. My primary reason for adding a Phase One back was to take advantage of more pliable files, improved color and tonal gradation, and greater resolution; I have not been disappointed! I am using my Phase One IQ260 on a Cambo tech camera, and enjoy the slower and more deliberate work flow. As a by-product of working with a Phase One back, I have adopted Capture One as my primary image editor; I prefer the interface, workflow and end product.3_NamibiaDT: Why did you select Digital Transitions to make your foray into medium format digital?

DT: Can you tell us a bit about your trip to Nambia?

John: I first worked with DT when I was having trouble getting answers from another vendor that I had previously worked with. DT has not disappointed; you always respond promptly and clearly. I had a tiling problem with my IQ260, and your tech people quickly helped me resolve the problem.5_Namibia

DT: Your trip to Iceland featured a near polar opposite (pun intended) landscape. What inspired you to travel there, and how did you plan your trip?

John: In April 2014 I completed a 20 day trip to Namibia to witness and photograph the country’s unique ecosystem with a group led by noted wildlife and wilderness photographers Joshua Holko and Andy Biggs. It’s one of the most arid regions in sub-Saharan Africa. My primary interest was the dunes at Sossusvlei which feature vivid pinks and oranges because of their iron content.6_Iceland

John: Iceland has been on my “Bucket list” for quite a while, due to its stark beauty, harsh conditions and geological history. I also prefer places where I can more closely interact with and get more involved in the environment… and take my time. Regarding planning my trip… that was done for me by the tour organizers, Joshua Holko and Daniel Bergmann. Following that 10 day tour, I hired another guide, Chris Lund, for 2 more days of travel to places that couldn’t be included in the first tour.7_IcelandDT: We especially enjoyed “Long Stretch of Black Sand Beach.” Can you step us through your mindset and process in creating this image?

John: My thought was for strong leading lines and a long depth of focus to convey the expansive nature of the scene. The image was captured with the Phase One IQ260 at ISO 50 on the Cambo Anniversary Edition with Rodenstock 40 HR-W lens at f/11. I wanted to have the patterns on the snow in the foreground illuminated by the sun, so the shadows would lead into the line of snow and wave receding into the distance. Additionally, I was hoping for the more distant section of the snow covered land to have some sunlight in order to draw the viewer’s eye more deeply into the picture. Sometimes, the foreground was illuminated, but not the background – sometimes vice versa – sometimes no illumination. But, there were enough thin spots in the clouds to encourage sticking with it. After about ½ hour of waiting, the thin spots in the clouds lined-up the way I had hoped. Also, the clouds did not clear completely, but thinned so that the sunlight was softened and not harsh. Sometimes you get lucky!8_IcelandDaniel Bergmann and I will be running our annual winter trip again in 2017 and bookings are now open and places are limited. Just drop me an email if you would like to join us.

New Zealand South Island Masterclass Workshop 2016

In a couple of hours I will be making my way to the South Island of New Zealand in preparation for my 2016 Masterclass workshop. It has been a full year since I was last in New Zealand and I am very much looking forward to returning to this magical country. May is a wonderful time to be visiting and photographing in the South Island; the fall colours will be just about at their peak and the weather is usually quite stable with fresh crisp mornings and rosy pink light.

We are looking forward to photographing around the island including several planned aerial shoots over the spectacular Southern Alps. Aerial photography from helicopter with the doors removed is an incredible experience over these majestic mountains. This photograph from the 2015 Masterclass was taken just on sunrise near Mount cook. Temperatures were will into the sub zero range and the resulting wind chill without the doors meant it was more than a little chilly. The results though are worth all the pins and needles…NewZealand-3313I am also looking forward to putting the new Canon EOS 1DX MKII cameras through their paces during this workshop. Over the last year I have been photographing with the Canon EOS 1DX and the EOS 5DSR 50 mega pixel camera. My experience with the 5DSR has been somewhat of a mixed bag and I have to say that on the whole I generally prefer the files from the original EOS 1DX (especially above the 5DSR’s base ISO of 100). Quite honestly, 50 mega pixels is just a whole lot more than I need for the vast majority of my photography and so I find myself reaching less and less for the 5DSR. The initial testing I have done with the new EOS 1DX MKII shows the files are considerably improved from the original 1DX; which in conjunction with the other improvements has me very excited about this new camera. I will have more to say about my thoughts on the new Canon EOS 1DX MKII in a future post as well as my thoughts on the current state of equipment in the industry.

For now, its time for a last luggage check and then its time to make my way to the airport. See you in the South Island of New Zealand.

Guest Photographer: Kevin Horsefield Iceland the Frozen North 2016

Two years ago I started a new segment on my blog for photographers with whom I have travelled before in order to provide an outlet for them to share some of their own writing and photography amongst a wider audience. It has been a while since the last post but I wanted to share some thoughts and photographs from Kevin Horsefield who recently accompanied me on my Iceland Frozen North 2016 Workshop. I have had the pleasure of travelling and photographing with Kevin now in Iceland on several occasions as well as Namibia, Antarctica and South Georgia. Enjoy his thoughts and photographs from our most recent Iceland trip.

Iceland the Frozen North 2016 – Kevin Horsefield

I ventured to Iceland in late Winter of 2016 with Joshua Holko and Daniel Bergmann.  As a veteran of their workshops, I know that we will be in the best possible location at the right time to maximize our photography. Daniel’s ability to read the light and Iceland’s fickle weather patterns are unparalleled.  Once at a location, Joshua can take over and helps his clients fine tune their compositions if necessary.
 
We seemed to be constantly dodging storms on this trip and dealing with rather flat light.  My solution was to shoot into the sun to bring a bit of drama to the scene.  With the sun being somewhat low on the horizon even at mid-day in Iceland, this technique can work well in these conditions.20160304-_N1A169620160307-_N1A1928
I also employ this strategy when I’m working with thermal areas, such as Hverir.20160309-_N1A206220160309-_N1A2097Backlighting also works well at Iceland’s famous black sand beach with the sun illuminating its translucent icebergs.20160308-_N1A1975
Some images work best with a conversion to black and white.  The color at sunset was so muted on this evening that I decided to strip it all away to emphasize this composition. I also added a slight blue tone to this image to convey the feeling of winter in Iceland.20160304-_N1A1731-Edit
