Been busy with work and dealing with the cold weather so haven’t been able to do much in photography this month.
I did get enough time to take the older Lensbaby optics out and play with them a bit on the Pentax k-1.
Very different using the double glass and single glass instead of the newer Edge or Sweet models but found them very enjoyable to work with. Fun to have to think about the aperture one wants first and then install the disk as opposed to setting the aperture in the lens.
I did get lucky one day and had an Egret land in the artisian well I was working around using the double glass.
Recently pulled out the old Pentax A50 f2.8 macro for a few shots of autumn leaves in the back yard.
This lens performs wonderfully on the new Pentax K-1. Though not a “true macro” with a reproduction of 1:2, I find the scale adequate and the IQ superb; plus it is such a joy to use.
I can see why vintage Pentax glass was noted for it’s quality, the colors are brilliant and the IQ is sharp for the area of focus. Bokeh is pleasantly pleasing also. This doesn’t seem to change on the new digital sensors either.
In fact, I find their performance is equal to or better than the newer digitally enhanced lenses.
Last month I was fortunate enough to get out of the snow and head to Death Valley for a well enjoyed photography trip.
For the past couple of years I have really been enjoying working with zone plates and decided to try my luck in the desert landscape.
Zone plates are very similar to pinhole photography in there is no lens and the resulting photo is from light diffraction rather than refraction through a glass element.
Zone plates however use a pattern of opaque and solid concentric circles resulting in a softer (less sharp) image caused by a larger amount of undiffracted light to reach the image plane. They are often reduced in contrast and produce a distinct glow or halo in the highlights. Continue reading →
ND Filters, often used to slow exposure times can also achieve great effects with flash.
Being a loyal Pentaxian, one of the biggest limitations to my setup is the flash sync speed of 1/180.
I often wonder where Pentax came up with this exposure and why they hadn’t developed a higher sync speed of 200 or 250 like many of their competitors.
Then I remember my film days and cameras that only had a sync of 125 and realize that even a shutter of 800 is slow compared to the speed of flash.
Flash or strobe work is really the balance of two exposures simultaneously.
Background or intent – exposed with ambient light, controlled by shutter, ISO and aperture plus Subject – exposed by flash, controlled by ISO and aperture.
Shutter speeds don’t really come into play during the flash part of the exposure, as most flash units fire much faster than the top sync speeds in cameras today.
Often, I find the strength of my studio strobes and non-ttl speedlights powerful enough on their lowest settings, that even with a low ISO 100 and the fastest sync speed of 180
I must still use an aperture of f11 or f16 to keep the highlights from blowing out beyond recovery.
When I have my ideal exposure setting for the flash, these small lens openings often cause an undesired effect,
they create a greater depth of field, taking focus away from the subject. Continue reading →
Don’t get me wrong, I love working is PS and have been enjoying learning new tricks in LR.
Also, it’s been over three years since I’ve even picked up any of my trusted film cameras.
Selective & soft focus through the lens.
My passion for photography actually started in the darkroom and not behind the lens, so I’ve always been enamored by the tricks and techniques for post production.
The ease and speed of being able to burn/dodge, fine tune, stack, create multiple exposures or mask for precise detailed exposure; almost every software now provides these tools for the photographic enthusiast.
When I first started with a digital camera I thought instant preview (so long polaroid backs) and eliminating developing chemicals was the only real advantage over film.
Now so much more data is recorded at the same time & in the same place, it’s incredible. Shutter & f-stop, exposure, copyright info, location, even star tracking.
No more pocket notebook and tear sheets that I would misplace and desperately look for a month later.
The digital age has brought more of photography to the masses than anything since Kodak’s “a camera for every household.” Continue reading →
