By the way the sign on the far right....is lit by clear MV...while the sign on the left from it is MH! You can see this picture is not grainy...unlike my other picture here is due to using LOWER ISO and longer shutter....that is a result of a clearer picture...but a negative is you must maintain your camera not to shake or move....so tripod or a magnet attached to camera on a non moving or shaking metallic platform will help a LOT
Nice clear night pic Jace and thanks for the tips, I think I need to get a tripod or a camera mount before I start taking night pics. Mine were either too blurry or too grainy to be posted here...
Are the signs that are lit up reflective or non reflective signs, The signs that used to lit here were reflective but they still lit them anyways. Our sign lights used coated MV and HPS and before that strip fluorescents
The grain is due to ISO set too high.....blurry without grain means good ISO but too much movement while snapping the picture...
if you notice...see the tail light making a line? I used 2.5 second exposure, 80 ISO (the lowest my camera had) and NO flash....I believe I used either a tree or a fire hydrant as a support and held onto it tight....
If it's not windy...then just put the camera down on a flat platform...turn on the auto shutter (timer) and set the ISO lowest setting...and have a longer exposure time (if setting is available....I would think its in the night mode.......or use Manual settings and play with the camera)....put down the camera...press the shutter button.....and RUN!!!!!! BEHOLD..a CLEAR PIC!!!!
By the way yes signs are reflective...we don't use HPS on signs as far as I know...we did use to have liner florescent...(in MD) and then they started using coated MV....and later MH...then the last few years (2000-2008) they installed clear mercury vapor....Today? I THINK icetrons.....I saw one sign with somewhat bluish hue lit sign! And very bright but nicely diffused!
nope, not exposure time....its sensitivity to light......have you seen the numbers on films when you buy films for film cameras? You've seen those that says 100, 200, 400 on the film box.....same thing pretty much....although it works a bit differently on digital cameras but basically same thing..
Metal halide highmasts are also exist in Israel, but not on the roads, but in public and urban areas such as one of the central bus station near Canyon Haifa mall in Haifa and in Haifa University.
All of the highmast that lights the roads in Haifa are still HPS.
For external signs illumination, we uses fluorescents (T8 of 36W) and MH lamps.
Like colored and regular MH lamps, HPS lamps also used to light building as the orange color lamps, together with the magenta, blue and green MH lamps.
Unfortunately, my camera (Canon PowerShot A1100IS) can't photograph pictures of night sences well because of the automatic shutter speed adjustment, which cause a longer shutter opening time in a night sence, which results in smearing.
The only option in my camera to disable the automatic shutter adjusting, is by using the "EASY" mode, when the camera behaves like a cell phone camera. However i can't change the resolution in this mode, and this often results in pictures as large as 5MB.
thats why you need a tripod or a magnet stand.....I used longer shutter time...that is a GOOD thing.....easy mode will cause grain.......I was using a Canon Powershot 1100IS too! So we both have the same camera buddy! You need to reread above to see how it works.....a longer shutter makes much better nigh scenes..but you need to keep the camera still....note the car was moving thats why you see a long red light, which is because of longer shutter.....a quick shutter is terrible for night shots....causing grains...
