Thanksgiving Sunsets

Over the Thanksgiving break I took the opportunity to enjoy some warmer weather and take a series of sunset photos.  The clouds were ripe for a great sunset, but just before the sun went down the wind had a different idea.  The wind picked up and cleared out what was going to be a very colorful sunset and left with this little band of clouds.  I attempted to do things right in camera and not use HDR for this sunset.  I used a 3 stop hard edge neutral density filter since there is practically no elevation differences in the landscape of the northern plains to even out the exposure.  I then transferred the files into Photoshop after my usually adjustments in Lightroom and added an LAB processing effect to the photos.  LAB processing brings out the natural oranges in the photo and adds to the saturation without degrading the image.  I toned that layer back to get the sunset the bright orange that I experienced that night.  I put the sun in the center of area toward the bottom third to get the most amount of sky possible and to crop out the farm buildings to the right side of the photo.  I normally would include those in the photo, but these wouldn't have added to the photos.

This photo was taken just a minute or two before the very top photo.  To see the difference in LAB color effects and regular process scroll back and forth between the two.  I cropped the other file to a 16:9 ratio because I didn't like the fence line in the photo below.  

These were the clouds on the backside of the sunset.  I thought these would stick around long enough, but again, the wind had a different idea. I took this photo with my fisheye lens and marginally straightened the horizon line in Lightroom.

Using a 10 stop Neutral Density Filter

During the early morning hours of the Thanksgiving holiday I took the opportunity to try and get some sunrise photos.  The skies were cloudy the previous evening, but they were forecasted to break in the night and be partly cloudy for the morning sunrise.  They were off by about 2 hours.  Sitting in a hayfield, I anticipated the sun to break on the horizon and reveal a beautiful sunrise, but it just didn't show itself.  So I used a little creativity and an opportunity to try using some older filters I had along with a new one I had purchased on sale earlier in the week.  In this post, I not only wanted to show what the possibilities are with filters but what surreal beauty they can add to the mundane.

In this first photo, I set up my camera and took the picture with a bare lens.  The clouds were streaking that day and it made for an interesting shot.  This photo was taken with a rather fast shutter speed which froze the clouds in the photo.  

I then placed my old trusty 6 stop neutral density filter on the front of the camera.  This allowed me to use a shutter speed that was much slower because the camera was now seeing 6 stops less light than before.  The slower shutter speed captured the clouds movement which gives the photo a better feel and mood than static clouds.  

Finally, I put the 10 stop ND filter on my camera and took a couple shots.  The color is a little different in this photo because the sun had now risen a little more into the sky and the clouds were starting to clear.  I took the liberty of saturating the colors a little more to give this a better feel of warmth.  If you notice, there isn't any static subject in the clouds and the are filled with silky smooth streaks.  I was worried initially after viewing this photo that my new filter was going to produce a magenta color cast which is sometimes troublesome for a 10 stop filter.  The colors were much different than the 6 stop.  Again, the sun had risen a little more and the clouds were beginning to break on the horizon.  This photo was also about 4 minutes long compared to 30 seconds of the other photo.  I was planning on taking a couple more shots, but not being prepared for the very cold wind that morning I decided to call it a day and head to eat some turkey.

Wanting to give the filter another shot at giving me the type of photo I want and to make sure I wasn't seeing a color cast, I stopped on the way home to capture this sunset.  The clouds were amazing this evening and the 10 stop filter added the drama I wanted to this photo.  There was a much brighter almost like the sky was on fire show 30 minutes later, but I was on a road that made it impossible to stop and get a shot.  I was very happy with how this photo turned out.  I didn't have time to get all different types of filters for this shot so I took two separate exposures, one 90 seconds and one 120 seconds.  I combined those photos in Photoshop to make the final shot evenly exposed.  

Thank you for viewing.

Starry Nights

Over Thanksgiving, I took the opportunity to sneak out during the night hours to see if I could capture some night sky photos.  In my previous attempts, I was either too tired or clouds were present and it just wasn't worth it.  Since everyone was tired from turkey and the rush of the day, there was an early turn in.  Knowing the area as I do, I had a good idea where I could go that I wouldn't be disturbed.  I also knew that I didn't have to go to far out of town to get a good area to see the stars.  If the night started out a failure, I could take the 5 minute journey back home and get myself to bed.  The night wasn't as cold as I thought it was going to be so it things started to work in my favor.

I initially planned on getting a couple night shots, try a night panorama where I could get the entire Milky Way in the photo and do a little star trail action.  I purchased a remote timer some time ago and never really used it to date.  I tried to familiarize myself with it while sitting in the car at the time, but it just wasn't clicking in my head.  So I tried to do a lot of the stuff manually.  The initial challenge with this is keeping the proper shutter speed to keep the stars sharp.  In night photography you can only have a certain amount of time before the stars start to blur.  If you want a crisp photo of the stars, you have to use 600/focal length.  This will give you the longest shutter speed you can use without trails.

I tried 3 different lenses over the course of the night for a couple reasons.  I read that a fisheye would give me the greatest amount of sky in my photos; therefore, giving me the best single shot of the Milky Way.  The initial problem with this is the fisheye lenses aren't known for their sharpness at their widest aperture.  I had to set my fisheye at f/5.6 to get nice, crisp, sharp stars.  This cuts down on the amount of light that reaches your sensor and doesn't provide as many stars.  The good thing about the fisheye is it is very wide, 8mm.  This gives the best opportunity to use a longer shutter speed.  I was able to capture a couple different shots between 35 and 39 seconds.  Second I used my Tamron.  I like my Tamron because it is fairly wide for a APS-C sensor lens at 17mm and it is sharp as a tack at f/2.8.  This gives me the chance to take photos at about 23 to 25 seconds.  The last lens I used was my Tokina.  That lens is a wide lens at 12mm but only a f/4.0 aperture.  It however is also sharp as a tack at 4.0.  Instead of sitting out in the cold for the entire shoot, I set the tripod right next to the vehicle.  I rolled down the drivers window, had a seat, and pushed the shutter button on the remote in the comfort of my bucket seat.  Most astrophotographers set their cameras up with the remote and leave them to do there thing for hours.  I didn't want to do that at all.

So where are the images.  Well, I have only had a chance to process a couple and not sure if the others are worth the time since they are kind of the same stuff, but I think this was a good start.  I might wait for a little warmer weather before I try the next round.

One cool thing to note from the evening, there was some type of meteor shower I didn't know about.  I saw in the hour I was out, four shooting stars.  I happened to catch 2 of them in my photos.  For next time, I need to focus on composition and post processing noise reduction.  Some of my images were very noisy.

Rokinon Fisheye @ 8mm, f/5.6, ISO 2500

Tamron @ 17mm, f/2.8, ISO 2500

Tokina @ 12mm, f/4, ISO 2500

This is a panorama of 8 different photos.  I attempted to get the entire Milky Way into the photo, but I cannot get them to line up when I attempt to make the panorama.  I may need to take a couple more photos up to get the entire system.  

Lastly, here is the one attempt at a Star Trail.  This is a single exposure using my Rokinon 8mm fisheye.  This exposure was 4 minutes long at ISO 1600.  It was a good start, but I was far too tired to continue getting the next 20 photos needed for a good star trail.  I hit the brakes of the car to give the foreground a little light.
