G9 Moon Shot
« on: January 12, 2009, 12:00:55 AM »
Had to try.  Never was much good at these shots.  Moon's really out tonight so I had to try.  Had to go a 1/500th of a second to get some resolution.  Never would have thought such a fast shutter speed is required.  Auto ISO, 5 f/stop.  Wish I was in Big Bend shooting the moon tonight.  Taken a bit west of Austin.

no to bad Al.

you should set the camera in manual mode so you can set the aperture to f8 or smaller, preferably f16 if the camera will do that, set the white balance to sunny and use shutter speeds starting at 1/125 and go faster from there. ISO should be 200 or ISO 400.

Never use any automatic settings for shooting the moon as the sensor is fooled by the entire scene, way too much dark and something really bright right in the center and the camera does not know what to do.

James, that was exactly the advice I was hoping for!  I had it in manual but didn't know what f-stop to use and should have set the ISO.  Thanks!

Actually, on a small sensor camera like the G9, diffraction will noticeably soften the image at f/8 or smaller. And the G9 only stops down to f/8 at smallest.

Shooting at f/5 on the G9 is probably a safe bet.

I recently shot the full moon on a clear night with these settings:
f/16, 1/180 sec., ISO 800

The equivalent exposures would be:
f/5, 1/960 s, 400
f/5, 1/480 s, 200

(hopefully I've done my math right :icon_biggrin:)

Great shot nonetheless! It was a beautiful moon this past weekend. Somewhere I read it was the brightest and closest it would be during 2009. Would have been great to be at McDonald Observatory!
Living so close to paradise, it is unbelievable.

Tom, thanks.  I'll give her another go soon.

Give it a go at other phases as well.  More contrast and more detail when shooting a crescent moon. 
WATER, It does a body good.

I agree, the full moon is nice and perty, but to get more contrast, try it at the different phases, of course your shutter speeds will need to be adjusted.

Just a thought... The G9 will be pretty noisy (chroma) at ISO 400, especially in the black sky areas which will be significantly underexposed. If you shoot a jpg with NR turned on there will probably be a lot of detail lost too. It may be better to go with the G9 strengths - low ISO for good image quality, and less noise.. and shoot RAW.

Bk, you are right about the noise at higher than say ISO 200 which I knew to avoid.  Interestingly, once I got a decent jpg I did take several RAW shots at the same settings.  For some reason they were horrible when compared with the jpg shots.  I have limited skills manipulating RAW photos, but for some reason out of the box they were blurred and did not show any detail.  How did I screw up?

You probably didn't screw up. It may be the raw rendering software your using or your understanding of Raw conversion (No offense intended). I assume you used ZoomBrowser for Windows or Image Browser for Mac. Remember, a RAW does not use any in-camera settings except white balance and the exposure solution. RAW does not even have a color space until rendered to jpg or TIFF. It will not look like a jpg, which is rendered in camera with the user entered settings for sharpness, contrast, saturation etc. RAW will most definitely look softer than a jpg as NO sharpening is applied unless you apply it. You are responsible for adjusting those levels to pull the most out of the RAW data when you process the RAW file.

Don't give up. It is a learning curve that can result in real benefit. But... It is more time demanding than shooting jpg, and only you can decide if the extra effort yields results that are worth your time and effort.

PS. The moon has been pretty awesome the past couple of days and a full moon is harder to capture well in a photo than most people think.

Yup, no offense taken and I have a heck of a learning curve for sure.  ZoomBrowser and then Photoshop Elements 6.0.  It's not intuitive:



Thanks again for all of your help.

Looks like the exposure adjustment was cranked up way too high in the RAW conversion settings.

You should have several basic adjustments available when you perform the RAW conversion to a TIF or JPG file:

- exposure (also called "brightness": probably don't want to touch this if your original exposure looks good)
- WB (white balance - auto or daylight would probably work best - remember that the moon is just reflected daylight)
- Picture Style (not sure if your software will have this or not, but probably just leave this as "standard", "normal", or "none")
- Contrast = 0
- Color tone = 0
- Color saturation = 0
- Sharpness = 3 or 4 (on a scale from 0 to 10)

Give that a try and see what it looks like. You can fine-tune things when you open the JPG or TIF into Photoshop.

I don't know anything about your particular camera, but if you can change exposure modes, try setting it on "spot" or "center weighted"  instead of "wide".
