Long exposure help

dkapp

Tonight was the first time I tried long exposures. I went out to shoot some sunsets, and stuck around until the sun went down. I've attached a picture of the Golden Gate Bridge. It was a 30 second exposure. There are some things I like about this shot, like the rocks & water. I'm not happy with the bridge and background. This is one of about 30 that I took. Most of the others were just tests while I tried to get the shutter speed correct. I feel this is proably my best shot from the outing...

What could I try different? All I did was curves & shadow highlight work in PS CS. I'm looking to improve my technique because I have some great ideas I'd like to try. Any help would be appreciated. Give me the good, the bad and the ugly. I have thick skin.



Thanks in advance,
Dave

What don't you like about the bridge and background?

Personally, I don't think you need to brighten the hills in the background. Keep them darker. In fact, try shooting the same photo again, only this time shoot it one stop darker. I have simulated it here:

Thanks for the tip. I shot this in RAW, so I'll go back & see if I can take it back a stop. I didn't like the bridge & background because they were too light. The bridge looked fake and seemed to degrade the quality of the picture.

I think the problem was the shadows / highlight tool messing with the bridge and background. I've gone back to the same photo & used a layer mask (thanks for the tutorial Andy) to keep the bridge & background natural while I brought out the details in the rocks in the foreground. Here is my latest attempt. I think its going in the right direction.



Thanks for your help!

Dave, I've messed around quite a bit with twilight shooting. I cheat.

I pick the shot with the best light on my subject, and the shot with the best sky color, and I combine them in Layers. If there are other parts of the picture that matter, I'll also find an exposure that puts them in the best light, and Layer it in.

I say 'find an exposure' because I'm not skilled enough to know what's working when I'm shooting. I bracket like a fool, up and down the range, every few minutes as the sky changes. Then I sort through the shots and look for the best combinations. The tool I use to see what I'm shooting is the Histogram.

One good thing about shooting in RAW is that you can make multiple 'exposures' of a single shot, in post.

My favorite sky color is the rich, dark, almost black blue that you get after the sun has dropped beneath the horizon.

Agreed. The original picture posted was too bright.

Bracketing is a great idea. When I was shooting last night, I tried to get the exposure right by using the histogram, but I just meetered for the entire shot. Next time I will meter for the sky/ water/ bridge..etc seperately. I'm not too skilled with PS, so this could be a great exercise for me.

Thanks for the ideas.

It's not hard at all, once you know the steps. Pick an evening, we could walk through it together in steps. Lotsa links here, too.

The only tricky bit isn't using the software, it's being precise with the brush to "paint in" the part of the image with the different light. It can be time-consuming. The final results are very rewarding.

I've been searching the net looking for some good tutorials. I started at Luminous Landscape because I can usually find good info there. The one piece of info that I came across worth mentioning is the "Rule of 600." It is used to determine maximum exposure time w/ a given focal length to prevent stars from streaking in the sky. Here is an example w/ the lens I was using. I had a Nikon 18-70mm lens set to 18mm.

18x1.5(1.5 focal length multiplier on Nikon DSLR)= 27mm
600/27 = 22.2 seconds exposure time.

In my photo, I was not concerned w/ star trials, but it is good info for the future.

If you have any links handy, could you please post them? Maybe in the future we can put together a thread to use as nighttime photography tutorial. Here is the link to the Luminous Landscape article.

Dave, my starting point was the Luminous Landscape piece on Digital Blending which has been linked here before. I just took the same info and applied to it twilight shooting. And where he shoots two frames, I shoot two hundred. And mine are spread over about half an hour or more, as the sun slowly recedes and the light on my subject changes, and then later the light in the sky changes.

I try to pair up the most gorgeous golden light on my subject, with a dark blue sky. Then layer them. The Luminous Landscape layering directions have one mistake: they say Layer/New Adjustment Layer/Hide All. It should be Reveal All.

that's zactly what i'd do !
shoot one long exposure for the creamy water, and another, shorter exposure for the bridge and hills. then blend in post.

ooooooooooh it's soo goooood

Thanks for posting. I'm excited to get out and try some of my new ideas. I just can't get the weather & my work schedule to cooperate

I'm hoping for some nice weather this weekend. My idea book is filling up and I'm starting to go crazy!

Does anyone else carry a small notebook to scribble down ideas and drawings while its still fresh in their head?

i'm always jotting down scenes, ideas, and places to return to as i drive by them. also, i note certain positions of the sun or moon, as they pertain to the season. finally, i'll also list places to get a bite to eat. it's *all* about the food, eh?

It is all about the food. My girlfriend likes to come with me as I wonder around the city just for the food. Nothing like snacking at the street vendors then trying a new place for lunch or supper. It makes for a great day and everyone is happy

Yabbut, look where you live... one of the best food cities in the world!
