Page 5: Basics
1 Introduction 1.1 Basics The Lime One is designed in a way that most experi- enced photographers probably only need to check out the quick guide. Additionally, this manual contains a detailed description of all the functionality and oper- ation of the Lime One light meter. -
Page 8: First Steps
1.2 First steps Step by step first use: The basic operation of the light meter with the default settings (aperture priority mode) is as follows: Attach the light meter to your camera via the accessory shoe. Power the meter on by pressing the push button Double press the button and use the wheel to go... -

by simultaneously holding the button while rotating the control wheel (see section 5.1 for more on expo- sure compensation). To lock the reading after framing using the eye piece, hold down the button . This locks the reading until the button is released. The meter shuts off automatically after 40 seconds of not having an input. -
Page 10: Iso Selection
The contents of the menu and each setting are de- scribed in the upcoming sections. 1.4 ISO selection The ISO, also called "film speed", describes the sen- sitivity to light of the used film or emulsion. It is the second parameter selectable in the menu. For long exposures of more than a couple of seconds, please look up and account for the reciprocity failure of the specific film/emulsion. -
Page 11: Battery
1.5 Battery The Lime One is designed to work with a CR 2032 coin cell. Similar coin cells like the CR2025 could also work, as long as they output 3V and have the 20mm diame- ter, though because of their thinner size, they have a shorter battery life. -

pretty fast from 100% to 90% • Using it very heavily during a single day, it may show a lower estimate at the end of the day and recovers the next day • After not using the meter for a couple weeks, it may even show a higher estimate directly af- ter powering on, going down to a more realistic level after a moderate amount of use... - Page 13 Please note when using the optional adapters: When storing the adapters for more than a couple of days: remove any devices attached to the adapter and re- move it from the camera if there is a tight fit. Since plastic can creep, leaving it stressed may decrease the clamping force of the integrated spring elements! Use the optional adapters as necessary, note that us- ing the dual-slot adapter backwards (rotated 180°) re-...

Page 14: Exposure Modes
2 Exposure modes For displaying and calculating the exposure parame- ters, there are four modes available: 2.1 A: aperture priority (default) You choose the aperture f-number, the light meter then calculates the appropriate shutter speed. Aperture priority is probably the most popular mode. By choosing a small aperture (big f-number e.g. -
Page 15: S: Shutter Priority
2.2 S: shutter priority With shutter priority, you set the desired shutter speed and let the light meter calculate the corresponding f- number to set on the aperture. This is helpful for example when shooting sports or fast moving subjects, when a manually selected fast shutter speed results in reduced motion blur in the pic- ture. -
Page 16: Ev: Exposure Value
the current settings is displayed on the scale usually used for displaying the exposure compensation. Dis- playing the current over- or underexposure in real time makes it easy to “scope out” a scene. This way it is easier to judge which areas will be over or underex- posed. -
Page 17: Exposure Compensation
2.5 Exposure Compensation All modes (except manual) allow the setting of the ex- posure compensation. This means that you can set over or under exposure in stop increments up to 3 stops over/under exposed. See “Basic exposure ad- vice” in section 5.1 on page 20 for more information on when and how to use this feature. -
Page 18: Operating Modes
3 Operating modes In the Setup screen there are multiple combinations for operating the light meter. In addition to normal mode there are two additional settings: inverted and low resolution mode. In normal mode the light meter is continuously read- ing and calculating the exposure values. -
Page 19: Low Resolution Mode
3.2 Low resolution mode Low resolution mode allows faster operation, when stop accuracy is not needed. Most cameras only allow the changing of the exposure settings in one stop in- crements, so it can be useful to have settings change and displayed in one stop increments. -
Page 20: Measurement And Calibration
4 Measurement and calibration 4.1 Introduction The light meter uses photo diodes to measure the in- coming light. The direction dependency of the photo sensor follows a Gaussian bell curve. Combined with the cone shaped aperture, it results in a field of view of roughly 35°. -
Page 21: User Calibration
bration screen “CALIB”, the current calibration offset (most likely 0.0) is displayed. 4.3 User calibration User Calibration using a reference camera: Any camera that has working metering, be it digital or analog, can be used as a reference for the light meter. Using a ‘... - Page 22 CALIB menu Be careful when trying to use incident/spot meters for calibration. The Lime One uses reflective metering like most cameras do, so the opportunity of error in- creases using a dissimilar metering method.

Page 23: General Exposure Advice
5 General exposure advice While the light meter will measure and calculate the most “neutral” parameters to set, the photographer still has to interpret these measurements and calculations. There is probably an infinite amount of information and advice on that topic, but as a start the following topics should at least cover the basics. -
Page 24: Exposure Compensation
Sometimes slightly underexposing a frame can be ad- vised, if blown out highlights would be problematic. 5.1 Exposure compensation The Lime One offers exposure compensation settings (see section 2.5). While most of the time a neutral ex- posure is sufficient, here are some situations in which... - Page 25 Challenging lighting Since the light meter takes an average across the frame, having bright elements in the background results in an underexposed foreground. Examples indoors: unshaded light bulbs, a bright win- dow, uneven lighting. Examples outdoors: Snow, a bright sky, the sun. In these scenarios overexpose by one or two stops (ev: +1.0...+2.0).
- Page 26 should still be visible, overexpose by two stops. Parallax error Similar to framing using a viewfinder or TLR camera, the parallax error must be accounted for. The offset of the meter in relation to the lens of the camera dis- torts the desired measurement area.

1/3 stop (optionally 1 stop) dynamic range * -3 ... 20 EV *: Below 0 EV: lower resolution, more noisy signal This device conforms to European (CE), US (FCC) and Canadian (IC) EMC directives. See hedeco.de for con- formity delcarations. -
Page 28: Service/Cleaning
7 Service/Cleaning 7.1 Cleaning With normal use the light meter should not need any servicing. If parts require cleaning, use solvent free cleaning solutions. If this is not sufficient, using small amounts of isopropanol alcohol is also fine. 7.2 Drill markings In case one wants to modify the placement of the shoe mount to a center or left-aligned position there are four laser engraved markings for potential drill holes... -
