Nikon SB R1C1 - Digital Camera Reviews & Photography Tips
“In our field tests, the R1C1 performed flawlessly with both Nikon’s D40x and D2Xs bodies. The lack of wires let us achieve lighting configurations that would have been difficult with larger flash units, which would likely have overpowered our subjects anyway. Also, the lack of wires makes setup and breakdown of a set much less annoying. If you’re shooting live subjects, such as frogs or bugs, some of the possible configurations may cause preflashes to help determine exposure, which will likely spook your subject.” “One last experiment was to shoot wide-open for maximum sharpness using the flash. The second image is a bit warmer, even though it was shot using the R1C1. In order to add warm to balance out the cold light created by the flash unit, I dialed in to the color temperature setting and increased it to 5900K. The increased color saturation is a bit more attractive than the image made in natural light.”
FE-4 Kononenko configured the hardware for the Russian MBI-21 PNEVMOKARD experiment, then conducted the 1h5m session, his first, which forbids moving or talking during data recording. The experiment is controlled from the RSE-med A31p laptop and uses the TENZOPLUS sphygmomanometer to measure arterial blood pressure. The experiment was then closed out and the test data were downlinked via OCA. [PNEVMOKARD (Pneumocard) attempts to obtain new scientific information to refine the understanding about the mechanisms used by the cardiorespiratory system and the whole body organism to spaceflight conditions. By recording (on PCMCIA cards) the crewmember's electrocardiogram, impedance cardiogram, low-frequency phonocardiogram (seismocardiogram), pneumotachogram (using nose temperature sensors), and finger photoplethismogram, the experiment supports integrated studies of (1) the cardiovascular system and its adaptation mechanisms in various phases of a long-duration mission, (2) the synchronization of heart activity and breathing factors, as well as the cardiorespiratory system control processes based on the variability rate of physiological parameters, and (3) the interconnection between the cardiorespiratory system during a long-duration mission and the tolerance of orthostatic & physical activities at the beginning of readaptation for predicting possible reactions of the crewmembers organism during the their return to ground.] FE-5 Kuipers performed operations with the NanoRacks Smartphone Module-17 experiment, to check out how smartphones operate in space. Activities included first reviewed briefing material, next setting up the camcorder for documenting video of the operations and then performing imagery and life cycle tests on two smartphones. Smartphone-2 was left powered on. [ISS National Laboratory partner NanoRacks LLC has a collaboration with Odyssey & Apple which enabled Odyssey to send two iPhone 4's to ISS as part of the STS-135 mission on 7/8/11. These phones are like the ones found in stores, but with certain alterations to meet NASA flight certification standards. The iPhone 4 was selected for its mix of features, which include a three-axis gyro, an accelerometer, a high resolution camera and screen, and the means to manipulate the image. The smartphones use the same software as their Earth counterparts, and standard tools were used to develop a new app called "SpaceLab for iOS" which enables the planned research aboard the station (the app is also available for people to download to their own devices). The hope is to use the compact hardware in future research studies and to augment crew performance and productivity in operational activities. Currently there are four separate experiments that will run on the smartphones via "SpaceLab for iOS": (1) Limb Tracker (a navigation experiment using photos of the Earth and image overlay manipulation to match the horizon to an arc to give an estimate of altitude and off-axis angles), (2) Sensor Calibration or Sensor Cal (using reference photos and the three-axis gyro and accelerometer for calibration to improve measurement accuracy, (3) State Acquisition or State Acq (also using photos, but this time to estimate spacecraft orbital parameters), and LFI/Lifecycle Flight Instrumentation (tracking the impact of radiation on the phones by monitoring radiation-induced single bit upsets, which are unintended changes in memory location values).] In COL (Columbus Orbital Laboratory), FE-6 Pettit powered on the USND-2 (Ultrasound 2) and VPC (Video Power Converter) hardware, connected VPC to HRF-1 (Human Research Facility 1), and underwent his first ICV (Integrated Cardiovascular) Resting Echo Scan in the US Lab, assisted by Dan Burbank who served as CMO (Crew Medical Officer) to operate the USND scans. Pettit then transferred the data from the USND2 hard drive to the USND2 USB for subsequent downlink. [Wearing electrodes, ECG (Electrocardiograph) cable & VOX, Don underwent the USND scan for ICV assessment, with video being recorded from the HRF (Human Research Facility) Ultrasound and COL cabin camera. Heart rate was tracked with the HRM (Heart Rate Monitor). There are dietary constraints, and no exercise is allowed 4 hrs prior to scan. After confirmed file transfer, the gear was powered down and stowed. Later, the data from the two HM-2 (Holter Monitor 2) HiFi Cards and two Actiwatch Spectrums were downloaded. The USND echo experiment uses the Image Collector software on the laptop and requires VOX/Voice plus RT Video downlink during the activity. Goal of the ICV experiment is to quantify the extent, time course, and clinical significance of cardiac atrophy and identify its mechanisms. The ICV experiment consists of two separate but related activities over a one-week time period: an ultrasound echo scan & an ambulatory monitoring session. The sessions are scheduled at or around FD14, FD30, FD75, FD135 and R-15 (there are fewer sessions if mission duration is less than six months).] FE-5 Kuipers concluded his first (FD15) ICV (Integrated Cardiovascular) Ambulatory Monitoring session, doffing the two Actiwatches and HM2 (Holter Monitor 2) about 24 hrs after the end of yesterday's "midpoint" activity (~10:25am EST). Later, Andre powered on the laptop and downloaded the data from the two Actiwatch Spectrums, copied the data from the 2 HM2 HiFi CF Cards to the HRF PC and downloaded Cardiopres data. [For the ICV Ambulatory Monitoring session, during the first 24 hrs (while all devices are worn), ten minutes of quiet, resting breathing are timelined to collect data for a specific analysis. The nominal exercise includes at least 10 minutes at a heart rate >
