Long Exposure Calculations

We'll be heading out for some night photography next month. Playing with long exposures is one of the thing you can't get around. Especially since I don't have any f/0.2 lenses in my bag.

Most lenses are sharpest (the so-called sweet-spot) around 2 stops from their biggest aperture (mostly around the apertures of f/8 and f/11) , but the problem is that these apertures kill the available light hitting the sensor of your camera. You could turn up the ISO (to 102400 if you have a Nikon D3s), but that gives you noise, and lots of it with most consumer dSLR's.

The only proper thing to do is adjusting the shutterspeed. Leave the aperture on its sweet-spot (f/9 or f/11), and the ISO at ISO100 or ISO200 (for the lowest amount of noise). But if you do that, chances are that you need exposures much longer than the available maximum on your camera, which is 15 or 30 seconds (depending on your camera). Which leaves you with the bulb setting on your camera. But how do you calculate the time needed for an exposure?

Bulb means that the shutter stays open for as long as you press the shutter release button.

Nikon Learn & Explore iPhone App

Nikon Learn & Explore on the iPhoneNikon (USA) launched their Learn & Explore iPhone app. The application is there for you to learn & explore the magical world of Nikon. Learn about shooting techniques by renowned photographers, see photos taken around the world.

A quote from Nikon USA;

Read an article on getting the most from your travel photography while you’re on vacation. Check information on adjusting depth of field or selecting the right shutter speed when you’re taking photos at your child’s sporting event. Access advice on the right aperture for shooting photos indoors when you’re attending a wedding. It’s all there on the Learn & Explore iPhone app. Photography information at your fingertips.

Nice for those moments when you're not busy at all. Light reading material is always welcome. Especially when you can learn something new. So I want this app.....

BUT unfortunatelly, the app is US only(?????). Why? Don't ask me. I already asked Nikon this, but they haven't answered (yet).

I guess Nikon World starts and ends in the US....

First Review New Nikon 70-200mm f2.8G ED VRII

It seems that Cliff Mautner is one of the (very, very) few lucky photographers who received his new Nikon 70-200mm f2.8G ED VRII a month early. His findings can be found on his blog, and I must say..... Those images are awesome (from a image quality point of view). Especially the VRII seems to rock.

/me is looking at his savings.... and cries silently

Anyway, the new 70-200 is a long overdue improvement for the 'old' 70-200mm f2.8G VR lens, since the old one performed not as wel on the FX cameras (D700, D3-range) as some would have liked.

Adobe Lightroom Quirks

The reason for using Adobe Lightroom is mainly because of the tight integration with other Adobe products, and a little legacy from my Microsoft days. So I had no real reason to look at the competition (Apple Aperture).... Until now (I guess).

The biggest drawback is that you can't open multiple catalogs at the same time. Something like having multiple personal folders within Microsoft Outlook. You can open them, access the content and if you want you can detach it again to save resources.
So opening a catalog means that you can't access photo's in other catalogs.... Therefor I use one (large) catalog. Mainly because I can't be bothered with the whole exporting and importing scenario to move (or copy) images between catalogs.
By the way, I suggested such functionality to Adobe (along with some other improvements regarding the syncing of catalogs). Now let's hope that they will implement this in version 3.0

This feature is something Apple Aperture since version 1.0 (if I recall correctly), and I get the feeling that I'm near the how far I can push Adobe Lightroom.

For the last couple of days I get the strangest behaviour from Lightroom. Importing photo's normally means you can add tags, and select a way of storing them on the hard disk. Lately it seems that Lightroom is having a mind of its own. Photo's end up all over the place. Tags are getting lost.

These problems are most likely cause by two factors in my opinion;

  1. A relatively large catalog which I browse a lot
  2. A lot of processing power going to other applications while browsing/editing photo's

I can accept that Lightroom is getting slower with thousands of photo's, but it shouldn't get a mind of its own when my iMac is busy doing all sorts of things.

Scotland Holiday 2009

Two and a half weeks driving around in Scotland. The weather was extremely good, which we didn't anticipate, so we didn't have enough t-shirts etc. Who would have thought that over two weeks of sunshine was possible in Scotland?

Saw lots of ruins, castles, sheep, churches, sun, beer, whisky, ruins, castles and stuff. No need to get bored when you're over there. Only downside to the extremely good weather was that I wasn't able to shoot many of those typical cloudy/rainy Scotland photo's.

The trip started with the ferry IJmuiden-New Castle. After that it was Dumfries, Oban, Spean Bridge, Struan (Isle of Sky), Ullapool, Thurso, Ballater, Glenrothes, and back to New Castle. Basically a trip covering the best parts of Scotland (we did miss the Orkneys though).



Also available on my flickr page or here.

Photofocus Question - Tilted Horizon

Oh yeah... One of my questions was 'answered' in the Photofocus podcast #09 by Scott Bourne and Rick Sammon (last question of the episode).

My problem' is that when I shoot in portrait mode that the horizon is always a couple of degrees off. The right side of the image is significantly lower than the left side. No matter how hard I try. Even though the problem is easily corrected in post-processing, it's annoying as hell.

Scott suggested a using the virtual horizon (which isn't present on the D300.... hmmm which gives me an excuse to upgrade ;-)), or using a hot shoe bubble (which is a whole lot cheaper). Rick mentioned possible lens related distortion. It's not the lens, because the problem exists in the range of 10mm wide-angle to a 200mm telephoto. So I'll be trying a hot shoe bubble for a while. Let's see if that helps.
