- pCAM version 1.13
-
- Designed by:
- - David Eubank.
- Designed and Programmed by:
- - Dian Suharto Iskandar.
-
- With David Eubank's assistance, pCAM was created to assist
- everyone working with Motion Picture, Still Photography
- or CCTV cameras.
-
- pCAM is the FoV (Field of View), AF (Aperture Finder
- for "splits") and DoF (Depth of Field) calculator with many
- film formats/aspect ratios, plus user-definable formats to
- choose from.
-
- *** [NOTE: IF YOU HAVE ALREADY INSTALLED THE BETA VERSIONS
- (any versions prior to version 1.0) WITH THE LENS
- EDIT DATABASE THEN YOU MUST DELETE "PWDART2A.PDB" OR YOU
- WILL GET AN ERROR WHEN CHOOSING A LENS WITH EDIT LENS.
- Launch PocketC --> MENU -> Applet -> databases,
- choose PWDart2a and delete it. ALSO DELETE "PCAM.PDB" AS
- IT IS NO LONGER NECESSARY PLUS "PCAM.PRC" AS IT'S FUNCTION
- HAS BEEN ALTERED.] ***
- -----------------------------------------------------------

- ** INSTALLATION:
- To install pCAM into your Palm Pilot, please use your Palm
- Pilot install program to install the following 3 files:
-
- pCAM.prc
- PocketC.prc
- MathLib.prc
-
- [Note: as default, pCAM.prc uses a Cinematography Camera
- for its icon. If you prefer a Photo Camera icon or a
- CCTV Camera icon, you can unzip photo.zip for Photo
- Camera icon, or cctv.zip for CCTV Camera icon.
- To install pCAM with a new icon, you must first delete the
- default pCAM.prc in your Palm device].
- -----------------------------------------------------------
-
- ** HOW TO USE pCAM:
- Tap on the pCAM camera icon to launch it.
-
- * SET UP PREFERENCES:
- - Tap MENU --> Options -> Preferences.
- - Select Camera then choose either CCTV, Cinema, Photo
- or User defined.
- - Select either meters or foot/inch unit.
- - Enter approximate infinity distance.
- - Average People's height for Monitor page mode (approximates
- object size of people -- 5' 10" is good).
- - Object distance inc/dec. Enter the length you would like
- to increase or decrease the focus distance in DoF or the far
- and near distances in Aperture Finder with the up/down keys.
- You can enter in feet, inches or both feet and inches (you
- can enter as 0 3 for 3", 1 for 1', 1 6 for 1' 6", etc).
- - Tap sound ON/OFF.
- - Tap OK to go back to FoV or DoF screen.
-
- * SET UP EDIT LENS:
- - Tap MENU --> Options -> Edit lens. Here you can add up to
- 20 lenses, either primes or zooms with their ranges.
- [HINT: Add a generic zoom 10mm-150mm with an F-stop
- range of F1-22. This will give you a sliding scale
- that can be quickly moved to change focal length for
- practically every lens desired]
- - Tap OK to go back to FoV or DoF screen.
- - To use your favorite lenses you must choose one of your saved
- lenses from the lens pop-up menu (bottom left). You must also
- activate Lens Edit by tapping on the checkbox underneath "Lens."
- [Note: Activating your saved favorite lenses by checking
- the Lens box limits you to the parameters of that lens.
- For instance, if you have a 10-100 zoom lens activated
- and try to find a matching FoV for a 200mm, pCAM won't
- allow you because the zoom parameters will already have
- been set to only go from 10 to 100. You must uncheck the
- Lens box (bottom left) to go beyond the limits of a saved
- lens parameter.
-
- * SET UP EDIT USER DEFINED:
- - Tap MENU --> Options -> Edit User Defined. Here you can add
- up to 10 user defined formats and CoC.
- - Tap OK to go back to FoV or DoF screen.
- - To use your user defined formats you must choose
- "User defined" in MENU --> Options -> Preferences -> Camera.
-
- ** USING PCAM
- - At the top right screen, you can choose the film
- format/aspect ratio.
- - At bottom right screen, you can choose between
- FoV and DoF.
- - If you have added your favorite lenses in Lens Edit, you can
- load each designated lens by choosing it on the lens
- pop-up menu (bottom left).
- - However, to activate the Lens Edit you must also tap on the
- checkbox underneath "Lens."
- [Note: Activating your saved favorite lenses by checking
- the Lens box limits you to the parameters of that lens.
- For instance, if you have a 10-100 zoom lens activated
- and try to find a matching FoV for a 200mm, pCAM won't
- allow you because the zoom parameters will already have
- been set to only go from 10 to 100. You must uncheck the
- Lens box (bottom left) to go beyond the limits of a saved
- lens parameter.
-
- ** FIELD-OF-VIEW CALCULATOR (FoV):
- - Choose your format/aspect ratio from drop-down
- list (top right).
- - Tap on the FoV icon at the bottom right. You are now in
- Field of View mode.
- - Enter the Lens FL, or D, or FoV based on your needs. Only
- the underlined entries can be changed.
- - When you fill in FL, D or FoV in foot\inch mode, you can
- enter it as 2 11, 2-11, 2.11, 2'11", 2'11 or 2 11" and all
- will automatically enter the 2'11" value after you tap OK.
- - Tap on the darkened icon in the lower right (with padlock
- icon) to lock in either the D, FL or FoV.
- - If you choose D (to lock Distance), then you can change
- FL and the result will be a new FoV. You can also
- change FoV (Horizontal or Vertical) and a new FL will be
- calculated.
- - If you choose FL (to lock Lens FL), then you can change
- D and the result will be a new FoV. You can also
- change FoV (H or V) and a new D will be calculated.
- - If you choose FoV (to lock FoV), then you can
- change D or FL and the FoV stays the same.
- [HINT: This is the most useful feature for finding
- matching lenses at different distances and keeping
- the same FoV].
- - Tap on the camera to show the current image size
- dimensions.
- - Tap on the television to see an approximation of the
- framing and object size of people.
- - Tap on the angle to see the angle.
-
- ** DEPTH OF FIELD CALCULATOR (DoF):
- - Choose your format/aspect ratio from drop-down list
- (top right). This automatically enters the correct
- Circle of Confusion (CoC).
- - Tap on the DoF icon at the bottom right. The DoF icon above
- the diskette (save) icon will darken. If it is already
- darkened then you don't have to do anything -- you're there.
- - Above the darkened DoF icon is a box that changes the
- increments that the F-stop will be changed. The choices
- are 1/4 stop, 1/3 stop, 1/2 stop, 1 stop or all stops.
- - In DoF mode you can change Object's Distance,
- Lens's Focal Length and\or Aperture, and the result
- will be the Near and Far Object Distance focus.
- - Use the up/down arrows to change your Distance, Aperture or
- Focal Length. Focal length will change 1 mm per tap.
- Aperture will change according to your F-stop setting
- (see above). Distance will increase or decrease according
- to the inc/dec you set up in preferences. Example: set
- inc/dec to 3" and it will change 3" each tap].
- [HINT: Tap on the diamond next to the up/down arrows to
- give control to your hard up/down keys. For obvious
- reasons you can only choose either distance or aperture,
- not both at the same time.
- - Besides automatically changing with the film format, you
- can also manually change Circle of Confusion (CoC) to suit
- your particular requirements.
- [WARNING: your manually changed CoC will automatically be
- saved when you close the program and will not default back
- to the original "factory settings" when you restart pCAM!
- Just remember to change the CoC back if you want the
- orginal settings which are 15.24u (microns) for 16mm
- and 25.40u (microns) for 35mm.]
- - You can also create your own formats with various CoC in
- User Defined.
- - Tap on CoC to see inch equivalent to micron.
- - Tap on the camera to show the current image size
- dimensions.
-
- ** APERTURE FINDER CALCULATOR (APER):
- - If you haven't already done so, choose your format/aspect
- ratio from drop-down list (top right). This automatically
- enters the correct Circle of Confusion (CoC).
- - Tap on the darkened DoF icon and it will change to APERture
- mode.
- - You can change Near and Far Object's Distance and/or Lens's
- Focal Length and the result will be the aperture needed to
- keep both points in focus plus where to set the lens barrel
- to achieve it.
- [HINT: This is for calculating "splits." Enter
- background subject distance (f) plus foreground subject
- distance (n), then enter focal length (FL) -- pCAM gives
- you the aperture needed to keep both subjects in focus.
- (D) shows you where to set the lens barrel to achieve it.
- Change either f, n or FL to get to an F-stop that
- you have the light for].
- - Use the up/down arrows to change your far Distance or near
- Distance. Distance will increase or decrease according
- to the inc/dec you set up in preferences. Example: set inc/dec
- to 3" and it will change 3" each tap].
- [HINT: Tap on the diamond next to the up/down arrows to
- give control to your hard up/down keys. For obvious
- reasons you can only choose either far distance or near
- distance, not both at the same time.
- - Besides automatically changing with the film format, you
- can also manually change Circle of Confusion (CoC) to suit
- your particular requirements.
- [WARNING: your manually changed CoC will automatically be
- saved when you close the program and will not default back
- to the original "factory settings" when you restart pCAM!
- Just remember to change the CoC back if you want the
- orginal settings which are 15.24u (microns) for 16mm
- and 25.40u (microns) for 35mm.]
- - You can also create your own formats with various CoC in "User
- Defined."
- - In find Aperture mode you can tap Aperture result box to show
- you the exact F-stop.
- - Tap on CoC to see inch equivalent to micron.
- - Tap on the camera to show the current image size
- dimensions.

-
- ** HISTORY:
- - Oct. 28, 1999 - pCAM v 1.13. Added two standing figures in
- Aperture Finder graphically showing near and
- far subject distances.
- - Removed Fixed Nodal Constant and instead changed
- the DoF and Hyperfocal formulas for more accurate
- close-up work.
- - Sept. 27, 1999 - pCAM v 1.10. Took advantage of new PocketC, v 3.10,
- allowing program to AutoSave like most Palm programs.
- - Sept. 16, 1999 - pCAM v 1.03. Fixed a minor bug in Aperture
- Finder that gave a fatal error when choosing
- the same distance for both near and far
- distances.
- - Implemented a Fixed Nodal Constant of 50mm (2in.)
- as a means to fine tune DoF. There is no hard or
- fast rule (as each lens make and model differs) and
- FNC is an attempt to average the nodal point
- distance.
- - August 31, 1999 - pCAM v 1.0, the official first release version.
- - Single pcam.prc file for applet and icon.
- - Added User Definable formats, maximum of 10.
- - Changed some "factory" formats and added others.
- - Changed some of the F-stops.
- - Added hard up\down key control.
- - Fixed some minor bugs.
- - Added more capacity to Lens Edit, totaling 20.
- - Can now beam pCAM to other Palms.
- - March 30, 1999 - pCAM v1.0b4 following the PocketC v3.01 release.
- - Some bugs fixed.
- - More accurate DoF calculation by changing
- CoC to exactly match the American
- Cinematography Manual.
- - Some new features.
- - March 14, 1999 - pCAM v1.0b1 released.
- - January 29, 1999 - David Eubank contacted Dian asking him to
- consider including cinema and photography
- to his CCTV FoV calculator. David also
- suggested adding the DoF and AF calculators.
- - November 1, 1998 - The previous version of PocketCCTV v1.1
- (was for CCTV only).
-
-
- BUGS:
- - So far, we've only tested pCAM on Cinema Cameras.
- CCTV and Photography Cameras may still need some parameter
- adjustments.
- - If you find any bugs please let David or Dian know.
