Long exposures in daylight

May 17, 2012 at 9:49 am

So occa­sion­ally (and hope­fully more often than that), I’ll drop in a lit­tle verbage amidst all the pho­tog­ra­phy here. Here is one of those times.

Ear­lier this week I read an arti­cle (1) that was related to doing long expo­sures in var­i­ous light­ing sce­nar­ios. Day­light, evening, etc. With the acqui­si­tion of a 5D Mark II, I’m look­ing for­ward to also try­ing new tech­niques than I had before. Not that they couldn’t have been done before, but I’m def­i­nitely want­ing to refresh the toolkit and new hard­ware helps with that.

With help from a local sup­ply shop (2) I got a new 3-stop ND fil­ter (3) for my Cokin P-series set, which com­bined with 2 other polar­iz­ers pro­vides 5 stops of extra expo­sure time. In other words, if you have a nor­mal expo­sure of 1/60 sec­ond then all else equal, with the above setup you would have an expo­sure of 1/2 sec­onds (1/60 * 2^5 = 1/2).

So yes­ter­day I grabbed a seri­ously fast sand­wich and went to the foun­tain down­town by Pack Square (4). It was very bright around 1pm so not great for super-long expo­sures. How­ever, the fol­low­ing did come out of the session.

Long Exposure May 16, 2012

13 sec­onds, f/32 at ISO 50. 100mm f/2.8 USM on 5D Mark 2

Granted, shoot­ing at f/32 is not rec­om­mended under nor­mal cir­cum­stances. But in the inter­est of a “long as pos­si­ble” photo I was try­ing to limit the light as much as pos­si­ble. Today is look­ing like another sunny day, but the next time it gets cloudy I look for­ward to see­ing what else can be done. Once I can get into the 2+ minute mark, then things like car move­ments can start to really blur.

Why do this dur­ing the day, when dur­ing the evening it is so much eas­ier? Two rea­sons, one because it’s there (5) and two, because I think that the energy of a space dur­ing the day with plenty of peo­ple and motion will give dif­fer­ent results than wait­ing until evening when the scene is calmer.

State of Equipment

September 28, 2011 at 1:00 pm

I opened my car trunk the other day in front of a coworker and he exclaimed “You’ve got cam­eras on top of cameras!”

Got me think­ing about why I have all this equip­ment. And I do feel like I have jus­ti­fi­ca­tion for all the gear, in this sense of a slid­ing scale for it that goes from money-making to art-making. The dig­i­tal stuff is way on the money-making end — por­trait shoots, wed­dings, etc. Totally reward­ing and def­i­nitely the lucra­tive work. On the other end is the 6x7, this mon­ster of a cam­era I’m just learn­ing to uti­lize. Beau­ti­ful work is com­ing from it, but very pos­si­bly will never recoup its cost in sales of pieces from it. And the film 35mm set falls some­where in between.

Could I do all my work with one set of equip­ment? I don’t think so. Best chance would be with dig­i­tal, but that doesn’t seem like very much fun. Thus, I see a need for each set. So in a cir­cu­lar way, I feel jus­ti­fied in all the gear.

But what to do with all of it? I’m reach­ing a slow point in the event sea­son — no gigs booked after early Novem­ber until Feb­ru­ary or so. Time to see if I can clear out any equip­ment — I know I want to sell my 6x45 set. Redun­dant for sure with the 6x7 and my GA645. I’m look­ing for­ward to the time of reflec­tion, time for exam­i­na­tion of the year’s work.
