Using Neutral Density Filters

Shooting Winter scenes isn’t as easy as it looks, especially on a bright, contrasty day. Exposure usually maxes out at around 1/1000 at f/22. Since the exposures are so short a lot of shadow detail gets lost. One way to combat this is using neutral density, or ND filters.

ND filters block light from entering a lens. This makes longer exposures possible in bright, high contrast lighting situations. ND filters come in different graduations, such as 0.3, 0.6 and so on. Each one reduces the light entering a lens by twice the amount.

This is a point of confusion with ND filters, since there are many designations for them. For example, a clear filter, such as a UV zero, reduces light by zero stops. An ND 0.3 filter lets 1/2 of the light pass, so it reduces the light by one stop. An ND 0.6 filter lets 1/4 of the light to pass, so it reduces the light by two stops. This decimal representation is called an Optical Density Number.

ND filters also have “ND 1” numbers. A 0.3 ND filter is ND 101, a 0.6 filter is ND102, and so on.

If you look at the markings on the outside of an ND filter, the designation is almost always given by its optical density number, or ODN. I use this as a guide to correlate the ODN to the number of reduced f-stops.

I made a small ND filter table available as a downloadable PDF. The table is small enough to print out and take with you on shoots. I printed it, cut it out, laminated it and keep it in my camera bag.

I was shooting on a cold, clear day this February at a park with a lot of snow on the ground. I shot with my Mamiya 645E using Tri-X at IS0 400. I developed the negatives in Ilfosol 3. Normal exposures tended around 1/1000 shutter speed at f/16 or f/22. Shooting at this speed washes out the highlights and shadow detail, which winds up muddying a black and white negative. Here’ s an example:

To get more shadow detail I used a 0.6, 0.9 and 2.1 on this shoot.

Here’s a shot using the 0.6 filter. Much better tonal separation and shadow detail.

Here’s a shot with the 0.9 filter. The 0.9 seemed to work well on this shoot, brining out more subtle shadow detail.

Here’s a shot with the 1.2 filter, taking the exposure down 4 stops.

ND filters help on bright days. It takes the exposure down allowing you to capture more shadow detail. I find them especially useful when capturing Winter scenes.

Shooting with the Zero Image 2000 Deluxe Pinhole Camera

I bought a Zero Image 2000 Deluxe pinhole camera and it came last week. The first thing I did was load it with 120 Tri-X and went to Belle Isle in Detroit to shoot.

Belle Isle is an island off of downtown Detroit and it’s a cultural gem. Two structures I wanted to shoot were the casino and the conservatory. The casino was never really a casino per se. It opened in 1908 and was used for events, dances, and meetings.

The 2000 Deluxe is an easy camera to use. It’s made of teak and the mechanical parts are brass, so it’s unlikely it will ever wear out if I take care of it. The 2000 Deluxe is a good camera to hand down one day. It’s a little tricking loading the film but it’s something I’ll get use to over time. To use it, there’s an exposure dial on the back. Just set your light meter as you normally do and take a reading in incident or reflective mode. The 2000 Deluxe is set at f/138, so just look at the inner dial where 138 appears and read the corresponding exposure time to the mark on the outer dial. Put a little mark next to 138 to easily find it, since the print is very small and hard to read if your eyes aren’t perfect.

The difference between the 2000 Deluxe and base 2000 model is the cable release mechanism and the bubble level on top of the camera.

I like using a cable release so I opted for the Deluxe version. On the baseline 2000 you just use your finger to open the shutter and close it. The transition is smooth, so it shouldn’t jar the camera sitting on a tripod if you buy the baseline model. I’ve only used the bubble level on one or two shots.

Film wise, the day was very bright and clear for January when I went shooting. I normally use Ilford FP4 at ISO 125 for pinhole photography, but I already had a roll of Tri-X in the camera and didn’t want to waste it.

One of the cool features of a pinhole camera is the nearly infinite depth of field. For pinhole composition, it’s always to have an object in the foreground to offset the background. With all objects relatively in focus, the effect looks good.

 

Belle Isle was owned and operated by the city of Detroit for many, many years. A few years ago the State of Michigan took it over and it’s been going through renovations right and left.

Visiting Belle is like stepping back in time when Detroit was the mechanical Silicon Valley in the early 1900s. Tons of great photo opportunities here.

Bottom line, do I like the Zero Image 2000 Deluxe pinhole camera? Yes I do, and I plan to . My other pinholes are Holgas, so this is a big, make it my main pinhole camera.
