double exposures, nyc



a couple more of my shots from new york in June. this time with flipped double exposures. they are both shot with the lomo diana, and were cross processed from velvia 100 film.

manhattan in flipped, double exposures


when arriving back to manhattan on the short ride with the manhattan ferry, I took this picture with the lomo diana. i first covered the bottom half of the lens with my credit card, and took one exposure. then i covered the top part, turned the camera upside-down, and did another exposure. I am really happy with how it turned out.

luckily I gave it two tries, because when developing the film, I realized I had messed up one of them. under you gan see how the "unsuccessful" one turned out (the picture itself is not that bad i think. it works well as a panorama-shot).


i actually came up with the idea for this technique when i was shooting in vigeland sculpture park. however, when i tried to do it there, i messed it up in the way that i was covering the bottom half of the lens in both exposures. here it's how it turned out:

the sunny 16 rule explained

(written by splatou)
when dealing with old cameras like the lomo lubitel 166b there are no fancy functions like light-metering. therefore, the photographer has to manually estimate the light, and choose a combination of aperture and shutter-speed, given the ISO value of the film to get the correct exposure. as this can be quite hard, some genius came up with the so-called "sunny 16 rule".

in short, the sunny 16 rule say that in sunny conditions (broad daylight), when the aperture is set to f/16, the shutter speed should be set to 1/ISO-value seconds. So if you are shooting with ISO 400, the right shutter speed for aperture f/16 is 1/400 seconds. if you take that as a starting point, you can begin adjusting to your preferred aperture or shutter by adjusting in "stop". in the table below are the normal available apertures. each step up or down in the table is one "stop" up or down. the lower the aperture number, the more the light

f/4.5
f/5.6
f/8
f/11
f/16
f/22


when it comes to shutter-times, every double or half (approximately) of the shutter speed, is one "stop" down or up. the slower the shutter speed, the more the light
250/1
125/1
60/1
30/1
15/1


and here comes the method of applying the sunny 16 rule, using an example.
let's say it is sunny, and you are using ISO 100. but instead of shooting f/16, which would have given shutter speed of 1/100, you wish to shoot f/8. this means you are adding two more stops of light compared to f/16 (see table above). this means you need to balance with two stops LESS light using your shutter speed, in this case 1/400. this can be summarized in the following table, combining shutter speeds and aperture (using ISO 100):

f/161/100
f/111/200
f/81/400
f/5.61/800


so, in sum, if it is sunny, start at f/16 and 1/ISO, and work your way through stops on aperture and shutter speeds. keep the balance, so if one stop brighter aperture, use one stop darker shutter-speed.

there has also been developed several expansions of the sunny 16 rule, so that it can be used in more conditions than just sunlight. here is a table summarizing this:
ApertureLight Condition
f/22Snow/Sand
f/16Sunny
f/11Slight Overcast
f/8Overcast
f/5.6Heavy Overcast
f/4.5Open Shade/Sunset

the way this table work is: you start with the light condition, and choose aperture thereafter. then set the shutter speed to 1/ISO, and start working your way from there upwards/downwards using stops and keeping the balance between light from aperture and light from shutter speeds.

and to finish it off, here are two shots where the sunny-16 rule is used to determine the exposure. i know they are not great picture-wise, but at least they are well exposed. (the pictures in the previous post are also according to the sunny 16 rule, btw).

lomo diana flipped double exposures



one of the most characteristic features with lomographic cameras is the possibility to make several exposures on top of each other. after experimenting with taking pictures of different motives on top of each other, I figured it gives a great effect to shoot the same object twice, either flipped, like here, or from different angels. both these are from de bolelaan in amsterdam, by vrije universiteit.

2-in-1 portrait II


same models as the last one, just now with expired 120mm KODAK color film. the spring has come and left, and it's now only 11 degrees in amsterdam. hopefully it'll be back soon. two days ago was the huge queensday celebration in amsterdam, I manage to shoot three full rolls, so expect a lomophobic queensday special soon.

lomo diana f+ exposure card

(by Simen P)
After looking everywhere for it, I finally found an exposure chart for diana lomo f+. The chart has exposure times for all aperture sizes for any conditions, from "Night, Star Light, No Other Light", to "10 Minutes After Sunset", and for ISO speeds from 50 to 800.



The full chart can be downloaded for free in pdf mode from INDIAN HILL imageworks.
