PeterKrenek 26 Posted July 26, 2011 Ahoj Lukas, a very nice star trail shot, the kind of light I like. The contrast of warm lights on the horizon vs blue i the sky is pleasing. I tried star trails on digital only once, I was pleasantly surprised how good today's sensors are (and still I do not have a FF sensor, just a 550D). The only thing that worries me is the look of the star trails when sharpened for web. They look a bit jagged. I try to bypass this problem by selectively reducing the sharpening on the trails after downsizing to web. At what ISO and aperture did you take this ? Best regards. Peter Link to comment
lukas ondrousek aka jozef 0 Posted July 26, 2011 Caf Peter, thanx for stopping by. I still have 400D - and I'm not that pleased :-)) Too much noise. Yes, they are bit oversharpened, but prefered this instead of loosing their visibility. I usually use selective sharpening(-> masking) for web presentation.Camera Model Canon EOS 400D DIGITALFirmware Firmware 1.0.4Shooting Date/Time 10. 7. 2010 23:34:32Owner's Name unknownShooting Mode Manual ExposureTv( Shutter Speed ) 440Av( Aperture Value ) 5.6Metering Mode Center-Weighted Average MeteringISO Speed 1600Lens 17.0 - 50.0mm Link to comment
PeterKrenek 26 Posted July 28, 2011 Well, 550D is not much better at ISO 1600 - I would not pleased either. I tried ISO 100, f/4.5, 30 minutes for my shot (Under the stars, version 3). The advantage of star trail shooting is that the stars are point sources that appear to move very slowly - allowing enough exposure even at lower ISO although they are quite dim. Of course, there is no doubt more trails are picked up at higher ISO, but there is the tradeoff between the amount of trails vs noise. Link to comment
lukas ondrousek aka jozef 0 Posted July 28, 2011 I was thinking more about 60D or so.For me the main problem is getting enough light into foreground - sky, star trails and noise there is very easy to compensate in PS. However if the foreground is black - I'm done. So for me it's a tradeoff between a noise from camera or noise from PS(when lightening shadows).And also - I would prefer spending less time shooting (ISO 3200/6400) and going to sleeping bag sooner :-))) Link to comment
PeterKrenek 26 Posted July 29, 2011 One solution I have seen other people do - you could do a blend - long exposure for star trails at a lower ISO and a shorter one for the foreground, focusing closer and at a higher ISO and/or with lightpainting, if the foreground region is not very large.

lukas ondrousek aka jozef 0 Posted July 30, 2011 In this case that method would work fine. But shooting scenery like this would be quite problematic:http://www.photoab.wz.cz/Latest_additions/imagepage12.html:-) Link to comment
PeterKrenek 26 Posted July 31, 2011 The photo in the link is a dream ! You are right, for that case it would not work. Link to comment
