Northern Lights - Raspberry Pi Forums

-

last night lucky enough catch aurora borealis picam.

used night exposure image parameter , exif data reported iso of 1250. pic came out greenish tint northern lights , know white watching them @ same time rpi running. lights in sky little washed out, surprised when generated video of image sequence , saw pretty cool video. post video when real world. bandwidth way small out here.

tried manually set iso 1600 , got expected results. camera limits out @ 800 , produces indistinguishable blobs instead of identifiable images.

question is, can picam take pictures @ iso 1600. if so, how? trying little more realistic color , definition images.

using b+ 2 model raspbian version #781 dated apr 21 2015 , can't internet rpi before leave great white north.

afaik iso 1600 mode possible in "sports" mode uses short shutter times. because high iso causes unacceptable noise longer exposure times. many people want try anyway, firmware apparently locked configuration.

low-light targets aurora challenging dslr cameras, i'm amazed got @ pi cam. sensor 1 factor , tiny f/2.9 lens also. if use aftermarket m12 type board fast lens f/1.8 or f/1.4, can little better @ least.

hello everyone, name kedi.. make system connecting raspberry pi 2 , arduino uno arduino adc of 1 dust sensor sharp gp2y1010au0f , 4 gas sensor. want show decision of air quality system in running text @ p10 16x32 led dot matrix display. in raspberry pi 2, connect p10 pins in gpio25, gpio12, gpio16, gpio13 & gpio26. now, i'm finish circuit , don't know must connect p10's vcc & ground (red & black wire). can me? , code in python controlling p10(1r)-v706 dot matrix?.. regards, kedi i can't python code (did mine in basic on risc os) regarding power, panels each require 2.5a, you'll need separate supply them. if attempted power them pi, pi's polyfuse blow immediately. alternatively, use supply capable of giving 10a supply both panels , pi. raspberrypi

hi, thank help. question simple: how convert raspistill data opencv processing. code: select all def capture(settings, width, height): command = "raspistill %s -w %s -h %s -t 200 -e bmp -n -o -" % (settings, width, height) imagedata = stringio.stringio() imagedata.write(subprocess.check_output(command, shell=true)) imagedata.seek(0) im = image.open(imagedata) buffer = im.load() imagedata.close() return im,buffer code: select all image1, buffer1 = capture(camerasettings, testwidth, testheight) cv2.imshow('image',image1) want use different opencv processing techniques, before need know doing wrong. bests svato raspberrypi
