Next, remove the white balance lens from the lens box and screw it onto the top front of the scanner.ī. Make sure the lighting conditions in your environment are set to what they will be during the scanning process.Ī. White Balance Calibration: Before you begin scanning, you need to perform the white balance calibration on the scanner. Hint: You can click on any image to see a larger version. This document guides you through scanner settings and collection procedures using the Konica-Minolta Vivid 9i, a turntable and Polyworks IMAlign software. If color is important – use good lighting (it can make all the difference). CAST has a three light setup that uses white flicker-free flourescents that is available for checkout. If the color properties of an object are important to your project, then we advise to use additional lighting to ensure more accurate color capture. _ Additional lighting – optional (not shown above) Note: In addition to capturing surface information and detail of an object, the VIVID 9i also captures color (RGD) data. _ Small black case with cables and accessories The Panasonic Toughbook is most commonly used with VIVID 9i and has the required configuration. Note: The laptop must be 32 bit with Windows XP with a PCMCIA card slot and serial connection. If you are going to be off the network, then you must borrow a license from the Polyworks license server to be able to use the software. _ Laptop with Polyworks installed (with REQUIRED Plugins Add-on). _ Turntable – optional (Medium black hard case) _ VIVID 9i Scanner (Large orange hard case) The Minolta is also meant to be plugged in, so a generator or alternate power source is required when working outdoors. Any planned outdoor scanning should be done at night or under a blackout tent. It will not work in direct or indirect sunlight. Note: The Konica Minolta VIVID 9i is best suited for indoor use. If the camera indicates Good, take a test image to visually check your white balance The camera should indicate “Good” or “No Gd” – if “No Gd” try againĥ. Use the shutter release button to capture a photograph of healthy green grass in similar lighting as your intended subject (e.g. Hold down the “WB” button until “PRE” begins to flashģ. Hold down the “WB” button and rotate the rear wheel to select the “PRE” setting, release WBĢ. To use the White Balance Preset option, follow these instructions to capture an appropriate custom WB image:ġ. However, even when capturing RAW images, the image preview on the camera’s LCD will use the white balance setting, and will therefore be easier to evaluate exposure in the field. It’s important to note that the white balance setting is only applied to JPEG images saved on the memory card – RAW images are saved to the memory card exactly as they are recorded by the image sensor, without any processing. A custom white balance using the “White Balance Preset” option can be used for better images. Nikon D200IR Custom White Balance Resultsīecause some red light is transmitted by the IR filter, any of the standard white balance settings will produce reddish images. This would result in 100 total images, with two at each of the 50 positions (interval) If mounting the camera to the octocopter for example, one could set the Interval to 10 seconds, the total number of intervals to 50, and the number of images at each interval to two. Select Intvl*Shots: This setting ask you to set 1. Interval: Sets the amount of time between each interval using hours, minutes, and/or seconds (one second minimum)ģ. If using Start Time, make sure the cameras time setting is correctĢ. Start: Two options exist including “Now” (starts taking images right away) or “Start Time” (allows you to set a time (e.g. To use this setting, three setting must be set:ġ. – Intvl Timer Shooting: This setting can be used to take a predetermined number of images with a certain amount of time between each shot. Otherwise turning on compression will cut the size of RAW images from 16MB to 9MB – RAW Compression: If memory card space is not an issue, set to “NEF (RAW)” for no compression. – JPEG Compression: For highest quality set to “Optimal Quality” –Make sure you select “Done” after making adjustments to theses settings or they will be lost. – Optimize Image: Use these “Custom” settings and adjust as needed: Capturing RAW images will preserve all image information and give you much more control over editing later – Image Quality: Use either the “NEF (RAW)” or “NEF (RAW)+JPEG” image quality setting. – Rotate Tall: Set “Rotate Tall” to Off if the images are to be used for photogrammetry or GIS applications Along with the generic advise given in the Acquire Images for Close-Range Photogrammetry and Custom White Balance for Nikon D200 IR posts, here are some important settings to consider when using the standard or IR modified Nikon D200 cameras:
