As part of my exhibition “South of the Drake Passage” I will give a talk about the images and some of the history of Antarctic photography.
Exhibition: “South of the Drake Passage” comes to Hanmer Springs!
Opening Saturday 4th May the “South of the Drake Passage” exhibition will show for a month at the Amuri Gallery:
Blue fungi and a tale of two histograms. ETTR Part II
In part one of of this post I looked at exposing to the right. That’s fine if you are saving your images as raw files and don’t clip your highlights too much. Software can recover some clipping within reason. But regardless of whether you are using ETTR or converting your photos to jpegs in the camera, accurate exposure often depends on which histogram you are looking at.
What is “Expose to the right” (ETTR)?
From a series of short talks on camera fundamentals given to the Nature Photography Society of New Zealand.
How sharp do you want your photographs? Diffraction revisited (Part Two)
In part one I looked at the effect of diffraction on images made with my 40D.
Now for a fresh look at the subject.
How sharp do you want your photographs? Diffraction revisited (Part One)
Several years ago I ran a test on my camera to look for the effects of diffraction. Light bends as it passes through a small opening, the smaller the opening the more it bends. So the more you decrease the size of the iris of a lens (increase the f number), the more diffraction will blur the image.
Since the latest digital cameras have such small sensor elements, diffraction can start to be apparent at f11 or f13.
This is a nuisance. Often we want to go f/16 or f/22 to increase the apparent depth of field. What is the point of getting more depth of field on the one hand if the image goes blurry on the other?
What is it about photography?
(In praise of printing….one from the vault)
The thing I associate most with photography is terror.
Oamaru exhibition postscript
The exhibition in Oamaru was very well received. The Colin Mckenzie Lounge is an ideal exhibition space with a lot of natural light and room for at least 25 large prints. The clan tartans on the walls added to the atmosphere, and the whole thing worked wonderfully.
Talk: “Photography and the Heroic Age of Antarctic Exploration”
Venue: The McKenzie Lounge, Scottish Hall, Oamaru
Date: Thursday February 7th 2013 at 6.30pm
I’m giving this talk as part of the Oamaru Scott 100 and you are cordially invited.
The beginning of the twentieth century was quite similar to our own time in that new wave of photographic technology had swept the world. Anyone could and did photograph.
However there were important differences.
