    A couple of night sky shots. SONY NEX-3N, f/3.5 @ 17 mm, 30s, ISO 400, using 16-50mm kit lens on a tripod.

    I absolutely love that shade of blue in an evening sky. :)

    Me too, Bimjo. Since this was a 30 second exposure, I didn't even see the blue until after I took the pictures. I'm totally digging nighttime/tripod/long exposure photography :)

    Yeah, long exposures at night rock. ;)

    Wonderful pictures! I just hope my pictures turn out even half as good as these images when I shoot the Milky Way tomorrow with the 7.

    Those are beautiful.

    Why choose ISO400 and 30sec? Why not ISO200 and a stop slower shutter speed. What's the benefit of keeping it no slower than 30 sec

    I'm not being critical, I'm trying to learn and know nothing about this

    EDIT: Oops, sorry I just noticed you asked why I didn't shoot in 200 :) Only reason is honestly because I never changed it from what I had it set to before and I liked how my first picture came out.

    But my answer below is also true :)

    --------

    Basically I like to keep my ISO as low as I can to keep noise at a minimum. If I were to increase it to 800 or more, I would start seeing some noise in the dark areas. Of course, it's mostly only noticeable when zoomed in but I think the cleaner the better.

    Thanks! I'm sure the 7 can handle it ;-)

    And by the way, I shot this in raw and improved it a lot in Lightroom. Amazing what a few little tweaks can uncover. I'll never shoot jpg again.

    Lower the ISO for a longer shutter speed? Bad idea. 30 seconds are already too long according to the Rule of 500. I, for example, shoot most of my night landscapes at ISO 3200 and f/1.8 or f/2.8.

    I am trying to learn about long exposure night photography and had to look this up as I was unfamiliar with it. Here is an article that explains it pretty well for anyone else unfamiliar.

    I was wondering how you managed to avoid a star trail with a 30 sec. exposure. When I've tried that with my 16-50, I start seeing them after ~20 secs.

    It depends on much more than just focal length. For example, your position on earth, time of the year, pixel countvon your sensor (it doesn't matter when printed at the same size, but it does indeed matter on screen), your height above sea level and much, much more. I've developed a formula which includes these and many more data, and it can well differ half a stop from the rule of 500, but usually, you're safe with this rule.

    To the thread starter - the stars here already form micro star trails, some seconds less would've helped here.

    This is why I love TalkNex! I'm a total newbie with this so I love to learn. Thank you for the tip, it makes total sense. Yes I see the micro trails the stars are starting to generate. A higher ISO would let me take a shorter exposure leading to much crisper stars. The noise level at higher ISOs is actually pretty mild on the NEX, plus Lightroom 5 does a great job cleaning things up. I'll try that next time. Thanks again!

    Oh no! I don't have LR :( do you have bullet points on which areas you post processed (ex. Brightness, contrast, etc)? Ill be at Death Valley which below sea level and the widest lens ill have is a 19mm 2.8.

    I increased the exposure a tad, increased contrast a little, and changed the white balance since it was originally a bit too purple for me.

    I may have also tweaked the noise reduction ever so slightly to remove some grain when zoomed in.

    First, Death Valley in July???!!!! :eek:

    But I'm no one to talk, I once went there on a motorcycle in August, where it was just me and the crazy Germans and Italians. :p

    Second, if you're going to be shooting the night sky there, you may want to consider driving up to Dante's View, where you'll have about 5,000 fewer feet of atmospheric haze to shoot through. Plus, while down in the valley it's likely to be unbearably hot and less than photographically optimal, up there it will only be extremely hot and much better, photographically speaking.

    Free advice, and worth every penny! :D

    A 19mm 2.8 is okay for starting. And you don't need LR, Nik Software's Define 2 does a great job getting rid of the noise.
