I admit it.
I promised myself (and others) I would buckle down and get serious about writing on this here blog in a more regular fashion. I notice it’s been three-months to the day since my last entry.
Ok. I suck.
But the fact I suck isn’t really anything new, now is it? Nope. Not at all. It is, if I may borrow a bit of French, de rigueur for the likes of me. So this time I make no promises, but will instead attempt to rectify this problem by hopefully being more diligent. Oh well…. let’s get on to something photography-oriented, eh?
I learned something the other day. No. Let me clarify. I noticed something the other day and with any luck I will have learned something from it. Observe…
Not too bad a picture really. But it looks a bit soft. A bit grainy. And there-in lies the problem. There’s simply more noise/grain than I would prefer. But you have to imagine the shooting situation to better understand how I came to be shooting at ISO 800.
I ventured out the other morning as it was the first in which sunlight broke through the clouds in probably a week. With still fresh snow upon the ground I hit Aullwood Audubon Center and Farm (a convenient and short drive) early in morning in hopes of capturing some nice shots of the birds hanging out in the trees as they swooped to and from the various feeders.
Birds? Check. Sunlight? Check. What more does a photographer need?
Apparently a lot more.
To not spook the birds I elected to remain at a discreet distance and shoot with my 100-400mm f/4.5-5.6 lens. I had tried my 70-200mm previously and it simply didn’t have the reach I needed. After all, these particular birds I was after are all pretty small. Chickadees, titmouse, nuthatch and downy woodpeckers are pretty small birds if you didn’t already know this. Naturally this meant I would be using almost exclusively the 400mm end of the lens and I anticipated plenty of crop & zoom back in front of the computer.
Now, being Winter the sun never gets particularly high in the sky and so it was there wasn’t a whole lot of great light. Add in the fact that when shooting at 400mm the rule of thumb is to work to keep your shutter speed at or above 1/400 of a second to mitigate camera shake or motion blur. Granted, I was using my monopod and had the lens image stabilization active, but to be on the safe side I adjusted my aperture to around f/9 or f/11 (I wanted to hit the sweet spot of the lens), which required me to bump up my ISO to 800 to make it all work.
ISO 800 compounded by the need to fairly heavily crop & zoom is not a winning combination in my opinion.
Still… it was a nice way to spend a cold morning and with any luck I may actually remember this particular problem and work harder to get around it in the future.
But I wouldn’t bet on it.
