Mike Walker's Vademecum on an old Palm Pilot. No reciprocity tables, I'm using Acros ;-) . A small Olympus voice recorder for my exposure notes.Hi !
I'm making a small pocket "book" of all information I will need while on the field.
What do you bring with you ? The reciprocity tables for your favorite film, filters factors, and what else ?
I have the filter factors laminated to the filter file pockets. Then I have a card (slip of paper 4.25 X 5.5") I designed 20 years ago with space for title, date, film holder number, development, metered exposure, recommended exposure, bellows factor and filter factor . Then I have check boxes for camera & lens.
On the back is a table of reciprocity numbers for TMX, TMY, TXP, FP4 and HP5.
This prints out 4 on a page and I run it through twice to get both sides printed, then cut into quarters.

How close my closest focus for each lens is with bellows fully extedended and also without the final extension. This also tells me magnification factor at that distance and how far across the 'frame' is. This allows me to choose the right lens for a macro shot very quickly.
I also have a scale of mm of focus depth vs f-stop vs diffraction effect as taken from the large format photography article on diffraction. This lets me work out the distance between my two desired end focal points and translate that into an f-stop and also, from diffraction effects, how much I could enlarge the picture.
I've also got a table that tells me the amount of coverage that a grad will give me for each lens I own (e.g. a hard grad on my 80mm lens has 13% of the frame covered by the gradation - however my 240mm lens has 55% of the frame covered by the gradation - not so good for hard horizons.. These are the calculations that convinced me I needed some extra hard grads (which singh ray and lee make on a custom basis) - see Dead Link Removed for details.
The rest of my sheet is for my own data..

p.s. if you are wierdly OCD like me, feel free to copy the sheet for your own use..
A policeman friend has since told me that they are trained to look at cell phone databases searching for emergency contacts. Someone invented the concept of listing these with the letters ICE in front of the name. ICE = In Case of Emergency. Most people just list the names and the emergency people can't tell your wife from your pharmacist.
Hope this saves someone some time when seconds count.
