Moon pic question
May 13, 2011

Hey everybody.

Just stepped outside a few minutes ago and snapped this pic. I was on a tripod with a wired release. I'm actually kind of happy with how it turned out. I only bumped the sharpness one or two stops in DPP and then cropped it.

My question is: the sky wasn't black when I took the pic, it was blue. Kind of a darker blue as the sun had set but definitely blue. Is there a setting I could have used to keep the sky blue? I tried some longer shutters - 1/60 and 1/80 but I got some blur and the sky still came out black.

Is it simply no use? Just thought I'd ask as the blue sky with the white moon looked pretty cool.

Only way is HDR
In reply to lewynn, May 13, 2011

HDR is the best way to go if you need the Moon with out over exposure and the blue sky too...

Difference in exposure between the moon and the sky.
In reply to lewynn, May 13, 2011

The differences in exposure between the moon, and the sky (at sunset) were outside the limits of your camera.

It’s obviously not a problem for your eyes to look up and see a blue sky with the moon floating there (that wonderful gift of eye-sight); but for your camera, it’s not a trivial exercise. Essentially you have one light source overpowering the other. The moon is like a big spot light floating in the ambient, evenly lit sky.

  • eg. If you attempted to expose for the blue sky (ambient light)….you get an overexposed moon.

  • eg. If you attempted to expose for the moon (bright light source)…you get an underexposed sky.

You can try to take the shot when the exposure differences between the sky and the moon are much closer. Probably more like mid-day rather than at sunset, where the light reflected from the moon balances with the ambient light of the sky.

Or as suggested, try an HDR.

DOF isn’t an issue, so with the camera in manual mode, dial-in a wide aperture, set the ISO to 100 and let the shutter speed control the ambient lighting.

Point the camera directly at the blue sky and meter for the shutter speed (note the shutter speed).

Shot 1: Compose the shot for the moon and dial-in the shutter speed that correctly exposes for the moon. You'll note that the faster shutter speed for the moon exposure kills the ambient light of the sky.

Shot 2: With the composition still set for the moon, simply dial-in the shutter speed you just metered for the blue sky and take the shot. You'll note the sky will be blue, but the moon will be a bright overexposed light.

Now you have two shots to merge via your preferred HDR work flow.

Regards, Mike

Another way to do this without HDR is to simply layer the sky shot over the moon shot, and erase the over-exposed moon in the blue sky shot so that the correctly exposed moon shows thru.

Remember that the moon and earth are moving while you are making setting changes between shots. You may have to move your second layer a tiny bit over the first layer to make the "hole" line up with the under lying layer.

You will have the same movement/alignment problem in your HDR exposures BTW.

First an apology for forgetting which AWB setting but I think it's the cloudy setting that will bring out the blue in the sky at twilight

Thank you all for the replies!!

I'll give the suggestions a shot and see what I can dome up with.

I can't do moonpics hand held at all. I just can't hold things steady.

Not even with a 1/200 sec shutter speed?

Hehe, it's taken with my (s)old bridge Fujifilm S6500fd at 300 mm equivalent. It's easier and better now with 550D, with 55-250IS at 400 mm equivalent, but (for now) the weather don't help me at all.

That ones really nice.

I've been a little busy and been able to get out and look for the moon. I will soon though!

All these photos that are taken at 250mm are taken with EF-S 55-250, right? I'm asking cause I'm getting one soon. It's really great lens for taking shots of Moon. I'll put some photos when I get it...

Here is one taken handheld with a T31 and a 55-250 lens in the evening.

This is at full resolution. ISO 100, f/5.6 @ 1/640.
