Shooting the Milky Way...the REST of the Story:

Please see previous post before reading this.

I know from my blog statistics, that more people look at my photos than make comments, and I'm sure that some of you are not photographers.  I feel the need to have a little talk with you folks first, before going into the details of making my Milky Way image.

(Note to you seasoned photographers out there:  just skip the next few paragraphs if you wish, and go right to 'The Rest of the Story' below, because you will know everything I have to say to the non photographers who might be reading this.)

With that preface, I'll start with a WARNING:  For anyone reading this who still believes that most of the spectacular landscape images you see on the internet are SOOTC, (Straight Out Of The Camera), I don't want to burst your bubble or your enjoyment of my photo, so I won't be offended if you stop reading right now!

The fact is, photographers, and most everyone else, know the majority of photos on the web today, speaking primarily of landscape images taken by professionals or serious hobbyists, (I would be inclined to say at least 90%, but that's just my opinion), have been edited in some way, if only with minor adjustments such as cropping to straighten a horizon, changing to black & white, or adding a small amount of contrast or sharpness.  

Additionally, many of the amazing landscape photos we see on photography websites such as 500px and flickr, have been created by applying even more sophisticated post processing skills, such as focus stacking, light painting, combining multiple exposures of the same scene, (commonly called HDR), or by actually combining entirely different photos to make one image.  If you can recover from that shocking news, and want to know more about the modern photographer's world, read on!

For a few people, knowing this reality sometimes alters how they feel about an image; they think that an image's 'awesomeness' is compromised because it is somehow 'fake'.  Now, however, after many years since the invention of digital photography and the invention of Photoshop and other sophisticated computer editing programs, most of us welcome these advancements that have taken photography, combined with artistic imagination and interpretation, to whole new levels of beauty and creativity.  I've said before, that I bet if Ansel Adams were alive now, (who altered his images in the darkroom), he would have fully embraced and used this new technology to help create his images.

Now for a little background information for those not familiar with taking photos of the night sky.  And really, these are just my first impressions and observations after only a few hours of trying to take this photo of the Milky Way.  (You photographers out there with experience in this type of photography, please correct me if I am wrong.)

Taking only one shot with no editing, that correctly exposes the night sky, would render a distant mountain range in silhouette, and a close up foreground object that is not lit with any other light source, as too dark or under exposed. 

That being said, I think it would be nearly impossible to take a shot like mine with one exposure, where the wagon is positioned close to the camera and is artificially lit, for several reasons.  Focus: one couldn't focus on infinity or close to infinity for the stars, and still have a very close foreground object in sharp focus at the same time, without some compromise.  Exposure: if the night was black or very dark, it is not likely that one could correctly expose for the sky and at the same time correctly expose for the wagon.  If there was an artificial light source illuminating the foreground, and a very bright moon, or the photo was taken before the sky was totally dark, would this be enough of a compromise for one exposure to handle it all?  I don't know.  I do know that often, night sky photographers use artificial means to light a foreground object, whether by a portable lighting system, or even car headlights.  (Car headlights did not work for me on this image!)    But if you have light on the foreground object, how do you take a long exposure necessary for the sky, without 'blowing out' the bright foreground object?

The choice for many photographers dealing with this dilemma, who want an image with a properly exposed night sky and a properly exposed non silhouetted foreground object, is to take at least two exposures: one focusing and exposing for the sky, and one focusing and exposing for the foreground; and then combining them in post processing.

(I want to emphasis again that I'm a total novice here, and all this information, right or wrong, is what I came away with after just a couple of hours that night.  Being a non 'techie' person who barely understands how my camera works, I would love for you experienced photographers out there to correct me or add information that would help me understand night photography better.)

Now for The Rest of the Story:

When we got back to the motel that night, I looked at my images in camera, and from what I could see, I thought I had a few shots where I achieved a balance between having reasonable sharpness with minimal sky movement, acceptable noise level, and acceptable brightness.  (I wouldn't know for sure until I got home the next day and downloaded them to my computer.)  Of course, I had no interesting foreground, but I did have the silhouette of the distant mountain range and some trees silhouetted in the far foreground. That would have to do for my first attempt.

The next morning we were packed and ready to go home and I was waiting for Jeff to load our RZR onto the truck and trailer, when I glanced over at the driveway entrance to the motel.  For the first time I noticed that old wagon sitting in front of the fence.  I realized it was sitting in the right position and direction to have been in a composition with the Milky Way behind it.  I was SO upset when I realized I could have had a perfect foreground object and wouldn't have had to go any more than a few steps from our motel room!!! 

I stood there fuming for a few minutes, and then on a whim, I wondered if it was possible, however unlikely, for me to take a shot of the wagon....in bright midday sun....  and then have enough editing skills to make this wagon photo look like it was taken at night and blend it into my Milky Way shot!  What the heck, I was standing in front of it and my camera was right there, so I quickly took several shots at different exposures, hand held and with not much thought.

Well you know where this is going.  First I went through my images and found the best one of the Milky Way.  I did some very simple editing here.  In LR I increased the exposure a small amount, I increased the contrast a small amount, I increased the vibrancy a small amount, I moved the temperature sliders to the blue and magenta sides a small amount and I decreased the noise a small amount.  Done in about a minute. 

Then I started working on the wagon shots.  I first tried blending several exposures together to create an 'HDR' image, but that looked too fake.  I ended up taking one image, and began experimenting in Lightroom and Photoshop.  I did not do anything complicated or difficult.  My main concerns were the harsh lighting, the color temperature and tones, and the shadow under the wagon created by the bright sun. (I guess I can say that I did not use any 'artificial' light on the wagon - haha.)

Lighting -  I decreased the exposure and the brightness until I was pleased with the balance between the night sky and the wagon, making sure the Milky Way was the brightest.  I decreased the shadow slider and black slider in LR to see more detail on the side of the wagon and make the shadow under the wagon less harsh.  I wanted the lighting on the wagon to be soft and dim, yet light enough to see the details, like you would naturally see, if it were illuminated with a minimal amount of artificial light.  I also wanted to see the fence in the background but I didn't want the fence as bright at the wagon, so I used the graduated filter in LR to reduce the exposure on the fence and have it blend into the wagon.

Color tones -  Because the wagon was shot in bright sun, the temperature or color was on the yellow side and not the color tones of the sky or a typical night shot.  My goal was to have the foreground blend and compliment the color tones of the sky, but not overpower or upstage the sky.    After all, the Milky Way was the main subject of the image....or should I say the 'stars' of the show!  I used the temperature sliders and color sliders in LR to reduce the yellow and add a soft, cool color tone.  That's it.

Wagon Shadow -  Would there ever be a shadow under the wagon if this image were shot at night along with the Milky Way?  Yes, if there had been a bright moon or if there was an artificial light shinning on it from approximately the same direction as the sun was.  Somehow, it still didn't look quite right when comparing it with the Milky Way photo, so I flipped the wagon horizontally.  This worked for me.  The composition was more pleasing and the shadows looked more realistic.  The lower right side portion of the Milky Way photo was naturally brighter, I think because of the sliver of a moon that had just disappeared in that direction.  And, it was also believable that the shadow could have been caused by using an artificial light source, positioned high, close to the fence, and just outside of the right side of the frame.  Seemed believable to me.  I then burned the ground in front of the wagon on the left lower corner, to put that area in more shadow, as it would naturally be.

Finally I had to combine the two images, which was surprisingly quite simple.  I did this by using layer masking in Photoshop.  The first thing I realized was there was not enough room at the bottom part of the Milky Way photo to fit in the wagon and fence and still see the silhouette of the mountain and trees in the background.  So I added 1-2 inches of black canvas space to the bottom of the Milky Way photo, and that worked perfectly.  Behind the fence you can see the road and then a bit more of the ground on a little rise, before the light disappears and turns black.  That is basically where the two photos merge.  I don't particularly like the road in the image, and if I had been thinking, I could have shot the wagon from a lower angle so the road would have been hidden.   I think the lighting drop off  behind the little rise of ground past the road is believable, if the wagon had been lit by an artificial light source.  After combining the two images I cloned out the trunk and bottom part of the tree that was right behind the fence.  To finish, I cropped off a portion of the top of the image for a more pleasing proportion.

Well, that's my saga!  I'd appreciate any comments, or corrections, or additional information.   I think I could get hooked on night photography, but I have lots to learn!

Here is the technical information for the Milky Way photo (in the previous post):
Camera:  Canon 5dmk2, mounted on tripod, set on manual
Lens:  Canon 16-35mm L series wide angle, set at 17mm focal length
ISO:  5000
Temperature: 3800K
Exposure:  25 sec at f/3.2  (exposure time longer than 25-30 sec made star movement too noticeable)
Focus:  manual, set close to infinity

Here is a shot of the wagon:  (boring, no technical info needed)

I was pretty sure you used two photos, but your skill at doing it made me wonder if you did or not. i do agree that about 90 percent maybe more of photos on thew web have been edited. and some of the most spectacular ones the photographer has done the same thing you did, used 2 or more photos... that said. i love the way your photo looked when finished and i love most of the ones on the web. i am all for edits.... to look at this pic, we would never have guessed it is the one in your prior post

Sandra said...

forgot to say thanks for the tips, and especailly the one about adding black at the bottom, i had one that would no fit and now i know how

Una historia força interesant i ven documentada.
Una abraçada.

kristeen said...

Oh my goodness -- clever you. Thanks for the ideas and tips. Your the best for sharing.. I am still in awe over the milky way shot...Hugs

Bob Bushell said...

I am like the others, I prefer the pictures, and this is excellent image Karen.

ADRIAN said...

That's the way I'd go about it.

Linda W. said...

Thanks for sharing "the rest of the story." Love the image and interesting to hear how you achieved it.

Stephanie said...

Excellent shot too! Thanks for the explanation and the steps you took to achieve the image you had on Saturday.

Robin Lamb said...

Karen, thanks for the "full story!" Very interesting. I'm going to have to give it a go! I agree with you completely about editing. I can't draw and I can't paint, so I use the camera. I think Digital photography is the greatest thing! Taking the actual shot is only one phase of the process!

Laura~Pretty Pix said...

Great post, Karen, thanks for sharing!
I enjoy post processing almost as much as capturing the image.
Creativity is a wonderful thing.. my current post is a rose petal gone abstract!

Scott said...

Holy smokes, Karen. I'm blown away that it was two images taken in two places and one of them in bright daylight. You really outdid yourself. Way to go!!!

Barb said...

Karen, I always edit, but I don't think I would have attempted to put the daytime wagon with the night shot. You combined them seamlessly. I showed my husband (not a photographer), and he was amazed. Thanks for going through your steps. One of these nights, I'm going to take the plunge!

What Karen Sees said...

Thank you everyone for your kind words. I appreciate the time it takes to leave a comment. Scott, I kinda surprised myself! haha

The Furry Gnome said...

Wow! You are so far ahead of me! Thanks for giving us the details (and perhaps inspiring a few of us to experiment further). I did get my own Milky Way shot using approximately the settings you used for that. And I have to admit that I hardly noticed the wagon in the foreground when I saw you Milky Way picture. I remember thinking I just wanted to post shots that were. 'Right out of the camera', before I realized that virtually every photo benefits from at least a little editing. My underlying rule is to edit it to bring it as close as possible to what I actually saw

you-wee because said...

You really did a great job for your first attempt, Karen!!!

Margaret Adamson said...

Good explanatory post and gogrgeous image

Anita Johnson said...

Karen I found this to be fascinating. I assumed it was one picture. I was trying to get pictures of the Milky Way the other night and had to spend some time during the day scouting out the foreground for he actual night shot. I'm still a bit conflicted about the use of two photos, but you did a wonderful job here. I have a lot to learn and I do agree that almost all photos today have been edited in someway. I like that I can manipulate my photos to illustrate what I felt when I took the photo. It's not just the details but the atmosphere iand the mood! Editing allows me to add that to my photos. Thanks for taking the time to write down all the information !

Stewart M said...

This a great post - photographs are about expressing a photographers vision - people who get caught up in the reality thing need to think I bit harder about what photographs actually do!

I really like this image.

Cheers - Stewart M - Jakarta (for a few more hours yet!)

There is no shame about the digital darkroom so to speak. It's part of being a photographer and an artist. The end result has to speak to your audience and create interest and emotions in them. How that's a achieved is up to each and every one of us. And as you said all professional and hobby photographers are using it. Especially the pros. Love your before and after.

Absolutely beautiful photography. I really enjoyed visiting and will come back. Carol
