Flicker and Shutter Speed

dt stellar operates at a very high frequency – around 50 times higher than that of prosumer led lights they should be very resistant to the “flickering” phenomenon common in other leds however, when using a sensor based electronic shutter (“es” or “sensor shutter”) or a mechanical focal plane shutter (fp) with very fast shutter speeds that you may still see very subtle flicker (waves of light/dark) or high frequency interference (tonally subtle, but sharp, lines only 1 2 pixels tall) running parallel to the long side of the sensor these effects should be extremely minor, may only be visible when extreme amounts of contrast are added, and only affect extremely precise imaging tasks such as scientific metrology in niche scenarios where this is an issue you may experiment with the following remediations leaf shutter lenses use a leaf shutter lens such as the ones found in the phase one xf, phase one ixg, phase one ixh higher power level on stellar the flicker rate is fastest at maximum power, so increasing power will decrease the chance of flicker note that the flash mode can be used to decrease the power between captures and use the higher power only during capture longer shutter speed flicker is less likely the slower the shutter speed decreasing iso, increasing aperture, increasing light to subject distance, or adding a dt honeycomb grid, polarizing filter, or neutral density filter to the light can be used to allow a longer shutter speed
