Description

Finally there is a Android(TM) Color Meter that measures thesubtractive color mix using red, yellow and blue (RYB) as primarycolors!How to Use the App?To use the app you need a white surfacesuch as a white paper. Hold the white paper to the left of thecolor you would like measure. Direct the camera of your Android(TM)device so that the paper is filling up the left rectangle in theapp and the color to be measured is filling up the right circle inthe app.To get correct results you need to make sure that the samelight is falling on both the white paper and the color to bemeasured. Avoid any shadows on the paper of the color measured.This is more important that usually expected. Then press the"Measure" button to let the app measure the color in the circle.The app will then tell how much red, yellow and blue paint or dyeyou need to mix in order to get that color.What is SubtractiveColor?This application calculates the subtractive color mix. Thisis a completely different thing then the additive color mix thatmost are familiar with today since this is applicable on computermonitors, digital photography and so forth.You can think ofsubtractive color mix as a mix starting with a white surface. Thenpaints, dyes or inks are added to darken and to color the surfacewith all kind of colors. The more colors added the darker theresult. The paints or dyes used are often the three primary colorsred, yellow and blue. A mix of these colors can create most colorsand hues.The additive color mix used in computer science is theopposite. To understand additive color mix you can think ofsomething starting with a black surface. From behind this surfacestart to light up from colored lights. The more light the morebright and white the the result will be. Using the usual setup ofred, green and blue lights allows to create all the colors you seein monitors and in digital photography.This app deals withsubtractive color mix using the primary colors red, yellow andblue.CalibrationIn order to help the application measure the colorscorrectly you can calibrate it against the current lightingconditions. To do that, press the "Calibrate" button, point thecamera towards a white surface filling up the screen and press"Calibrate" again. The app will then adjust to the currentlightning conditions.Physical LimitationIt is not possible to mixred, yellow and blue paint or dye to create all possible colors andhues. Most importantly, total black can not be created with any mixof these colors. It is possible to come close if the maximum amount(represented as 1.0 in this app) is used of all the colorstogether. With this mix you will get dark brown. In all the caseswhere it is not possible to find an exact mix the app calculatesthe closest possible mix.How Accurate are the Measurements?A numberof issues makes it hard to measure the color exactly. The largesterrors will appear if the light falling on the paper and on thecolor you measure are not identical. This can happen if theAndroid(TM) or the hands of the user is shadowing the light or ifthe light got reflected on the hands or any other nearby objectsthat are not white. The effect of these lightning circumstances aremuch larger than one might expect.Secondly the Android(TM) devicesare slightly different from each other. However, both of theseproblems are effectively eliminated when the app is used forcomparison measurements. In other words, when the app is used inexactly the same lightning conditions on the same Android(TM)device, two measurements on different colors can be compared withtypically only small errors in the measurement.Got Feedback on theApp?Please send any feedback, ideas or improvement suggestions onthe application to [email protected]

PLEASE NOTE: POINT THE CAMERA TOWARDS A WHITE SURFACE - NOT TOWARDSTHE LIGHT SOURCE IT SELFHave you ever experienced that the colorsof your photos does not seems to correspond to the colors of thescenes in front of you? Let this app help you to get more realisticand better looking photos!The app measures the color temperature ofthe lighting so that you can set the appropriate white balancesetting on your camera. Problems have been reported on a fewAndroid(TM) devices and therefore you are offered a MONEY BACKGUARANTEE - if you are not happy with the performance of the app onyour device, send an email to [email protected] with the GooglePurchase ID and you will get a full refund. Valid within a wholemonth from the date of purchase.How to Use the App?Find a surfacethat is white or gray. A white paper with or without text worksperfectly. Just make sure to avoid any colors. Point the cameratowards that surface and click the Analyze button. The app willthen show the measured color temperature of the light that falls onthat surface. The app will also recommend a white balance settingfor you to use on your camera in these lighting conditions.What isColor Temperature?Color temperature is a characteristic of visiblelight that measures the hue of light from a light source. Colortemperatures are usually measured in Kelvin (K). Low colortemperatures (below 3000 K) are called warm colors (red andyellowish white) while high color temperatures (above 5000 K) arecalled cool colors (blueish white). Technically the colortemperature is the temperature of an ideal black-body radiator thatradiates light of comparable hue to that of the light source.Whenis Color Temperature Important?Color temperatures are of specialinterest in all kinds of color photography. The human eye easilycompensates for the color temperature of different light sources.Most cameras today have a feature called Automatic White Balance,AWB, which tries to do the same. In some conditions this works OK,in other conditions the results are poor. Many photographerstherefore prefer to manually set the white balance value on thecamera to match the color temperature of the current scene. Withthis application you can measure the color temperature before doingthe white balance setting on you camera to get a more accuratesetting.You can also use this app to learn about the colortemperatures in your environment. With this knowledge you candevelop a better understanding of how the color temperatures varieswhich helps you when you are trying to master the light and colorsin your photography.How Accurate are the Measurements?To measurethe color temperature accurately is a complex issue. On anAndroid(TM) device is it complicated further by the fact that alldevices are slightly different from each other. See the measuredvalues as fairly good approximations.Got Feedback on the App?Pleasesend any feedback, ideas or improvement suggestions on theapplication to [email protected]
