Time Lapse: Herstmonceux Castle, UK

The United Kingdom is renowned for its imperial heritage, but for us landscape photographers, its rolling plains, cliffs, and mountainous reliefs provide rare natural opportunities for us to capture. During my year residing in East Sussex, England, I tried to go on excursions to such sights as much as possible, from  the chalk cliffs of the South Downs to Hadrian’s Wall that defined the informal borders of England and Scotland, and the natural landscapes in between. Some of the image I have already posted, like the chalk cliffs of the Seven Sisters, and more are still to come in future Pic-A-Days.

Living in rural England was also an opportunity to escape the light pollution that plagues metropolitan settings like Toronto or London. Looking up on a clear night might convince you that perhaps those romance novel cliches like “seeing the stars reflected in your eyes” weren’t so overblown. Photography-wise, a nightscape with the absence of artificial light is perfect for long exposures, but best of all, time-lapse sequences. Being new to the genre, I bought a intervalometer unit for my camera and began experimenting. Here is one of my better attempts. I recommend watching in 1080p in full screen since YouTube heavily compresses the file.

This was compiled using 653 frames that were downsampled from 10 Megapixels to 1080p, about 2 Megapixels, and edited in Adobe AfterEffects. While the sequence was shot successfully, there were some limitations in terms of sensor noise that translated to the softness in the video, along with blotchy artifacts. And although I said there was no artificial light, this particular location in the garden grounds of Herstmonceux Castle had tungsten floodlights in the distance, trading absolute darkness for a better composition.

But through such experiments, I have learned some things to watch out for. Firstly, calibrating white balance is essential to getting natural looking night skies and is unfortunately done through trial and error, or if there is enough moonlight, using a white/grey card. For a less precise but more time-saving strategy is to set the white balance to Daylight and correct any problem in post. While it may not be most economic to shoot RAW that fills up a memory card quite fast, I think the same principles for image quality apply for space-hungry sequence shots. With RAW, there is much more headroom for post-processing, like white balance, that may save you from standing in the cold for hours again. I have yet to try this technique, but if you happen to have a power outlet near you (in a field?) or a quantum pack, shooting tethered would be possible. Lastly and nevertheless, a plethora of batteries, a sturdy tripod, and a dual battery vertical grip or AC power are key ways for smooth and interruption-free footage for compiling. Enjoy.

Checking In – Back From Europe!

Some of you know that for the past year, I was traveling continental Europe while living in the UK. While I didn’t update the CMS for the past few months, you can rest assured that a good amount of posts will follow this one to capture and reflect upon my experience, from British warships to nineteenth century coal mines, from meeting the pope on Christmas Day to getting lost in the Swiss Alps, from the nightclubs in Turkey to seafood in the Greek Aegean. I feel extremely fortunate to be able to have transcended various geographies and cultures on my journey across 11 countries (UK, France, Belgium, The Netherlands, Portugal, Switzerland, Italy, Greece, Turkey, Sweden, Denmark), a journey which has renewed and rekindled my historical and cultural interests with the goal of better understanding society and life. While I previously had my doubts, I stand corrected to say that the rewards of this trip were nothing pretentious; as a spectator, it was a stunning world with a breadth that encompassed more than I could have imagined.

Stay tuned as I continue my Pic-A-Day series along with my experiences of Europe in future posts!

Bringin’ it Back – Zoom Student Film Festival 2011

With an enthusiastic invite from my good friend, my former design instructor and the event’s staff sponsor, Walter Raemisch, I attended the 15th annual Zoom Student Film Festival for the second consecutive year. Departing from last year’s theme of internationalism and advancing socio-political democracy though film, the festival this year is emphatic on its theme of “Moving Forward, Giving Back”, in efforts to “recognize and honor the school and community that [has] supported Zoom through all its years”(see my post of last year’s festival). Accordingly, the venue for the night’s show is none other than Earl Haig Secondary School, the place where it all began fifteen years ago.

The atmosphere was quite different from last year’s event; much livelier and much more diverse with the performance of Earl Haig’s student body, adding a very inclusive touch. The evening started with a jazz performance by the resident music department as attendees filed into Cringan Hall to take their seats.

The lights dimmed and the reels started rolling with nostalgic scenes from notable classics of the past decades, much to the applause and cheer of the audience. The Earl Haig dance majors in the Claude Watson program accompanied the different movies with choreography of similar flavor.

As a whole, the prelude into the screening was well done; a holistically showing of student effort and school spirit, conveying the accomplishments and evolution of both Zoom and the film industry of the past decade.

Like the previous year, the featured films spanned abstract to comic, love stories to teen angst, stopmotion to full animation. The submissions poured in from across Canada and even from the UK. Below were some of titles screened during the evening Unlike last year, I can’t seem to find any of them posted publicly on YouTube or Vimeo. You are welcome to enjoy last year’s lineup, here.

Sigma 50mm F1.4 EX DG HSM User Report

Having accidentally dropped my old Minolta 50mm F1.4 on the London Underground recently and putting it out of commission, I was in search for a new ‘Nifty-Fifty” replacement. The choice was obvious: Sigma 50m F1.4, with its massive front element that promised superior vignetting control, wide-open sharpness, and of course a deliciously smooth bokeh with its 9 blade circular aperture. My previous experience with this lens was last year at Zoom Film Festival, where I used it on a Canon EOS 7D body with mixed results as the lens suffered from a backfocus problem, all too common with Sigma’s not-so-stringent quality control. However, it did make a lasting impression on me with an impressive build quality, which also meant that it was quite weighty for a classic 50mm focal length.

Luckily, I managed to snag a good copy of the lens at a good price, just in time for a trip over to continental Europe (more about this in future posts). Here is a quick report on its usability and characteristics, compared to my recollections of its Minolta counterpart. This is not scientific in any way, but reflects on its performance in practice.

Sharpness at F1.4 is fantastic, providing that extra care is used to check if the lens is focused on the intended spot. This caveat remains applicable to all large aperture lenses since the Depth of Field (DoF) is extremely thin at these settings which accounts for misfocused images. Sharper than my Minolta for sure. Center of the frame is certainly usable at F1.4 and reaches maximum sharpness at around F5.6. Corner performance is fair at F1.4 and gets progressively better relative to center performance.

Focusing Speed is average, even though it has a HSM motor which surprises me. Under dim light conditions, I haven’t observed any focus hunting, which is a redeeming factor. I would like to mention, however, that the lens did not perform amazingly during continuous AF, which I suspect is due to my aging camera. But considering it has an average focusing speed like Minolta, Canon, and Nikon counterparts, think twice before using it to capture fast action.

Chromatic Aberrations are evident (purple fringing), but might be a nonissue with some post-processing. However, same cannot be said for Longitudinal CAs at large apertures, as seen below:

Fringing biases towards magenta and green with the former experienced before and latter experienced behind the focal plane. This is particularly bothersome at F1.4, and in the bokeh, which may render some shots unusable depending on your purpose, but clears after F2 or F2.2. To be fair, Longitudinal CAs are experienced by all prime lenses, although I didn’t have the same extremely pronounced effect with my Minolta. This, I think, is the lens’ biggest issue.

Bokeh is beautiful and really shows where all your money went to. This is where the lens really shines!

Coma can be an issue at wide apertures, but is not a big problem.

Handling is a mixed blessing. The high quality plastic and metal barrel exudes quality, but warrants considerable heft at 505g with its giant 77mm thread. You may like the thread size if you have other professional grade lenses that uses the same filter size, since sharing a CPL or ND filter could save you a lot of money. This is certainly not a light lens by any definition.

In conclusion, the Sigma 50mm F1.4 is all around excellent but with some minor issues that does not outweigh the good that you get with this lens. As previously with my Minolta 50mm, I will be using this lens a lot so I may update this report in the future. Also, I realize I haven’t posted on this blog for a while, but stay tuned as I have a number of posts in queue!
