A photography question

Thursday, September 29, 2005 by GoodMorphing | Discussion: WinCustomize Talk

I got a digital camera awhile ago.  The other night I was out at the beach experimenting with it.  I took this shot ( http://goodmorphing.wincustomize.com/photos.aspx?a=1&p=18&view=full ) which at first glance seemed like the moon.  But the moon is not in full phase now.  I enlarged that section and whatever it is seems to have something orbiting it.  Also, it is a very 'happy faced' moon.  I know from working with film I can kink the film as I wind it, or leave a bubble, or drop some dust during the development process.. but can a digital camera produce some artifact?

My digital camera has before.  I noticed when I have taken pictures of the night sky, that stars will show up that I didn't necessarily see.

Yeah... I noticed the camera was showing me more detail than I normally see... but a whole out-of-phase moon?  I thought it might be something on the lens but none of the other images had that.  The other thing I thought was that maybe someone was teasing me with a laser toy... could that be possible?

Wow, looks eerie, WHAT do you think it is?

some glitch that I don't want to happen any more....  my guess is dust.

In digital you don't have dust, although grain still shows up in low light, but what you have to watch for in digital photos is called "noise". But that isn't noise, it's too big to be. Noise is pixel per pixel, not a group like that. Maybe it was just a brighter star? It looks like you had a long shutter speed on which could have picked it up, but makes ya wonder where the other stars are or if this one would just be that much brighter?

I know what you mean by grain... I was kind of surprised at that.

Do you remember a device for cameras that was like a long wire with a syringe in the end that screwed into the shutter?  I was  hoping to find the same kind of thing for the digital camera, I have a habit of moving the camera when I click.  And I wondered if it is as good an idea to keep a polarizing lens on for protection as it was with the old camera?

thanks for your opinions.

I thought the same for a moment... but there is the other object.  Yeah, it was a timed shot with probably a long shutter speed and there was wind.

What  causes noise?

OH... maybe because of the long shutter speed, it picked up the dark part of the crescent moon?  that kind of explains it.

yeah, the longer speed allows more light in.

I think the word you're looking for is "cable release" on the wire that would trip the shutter. Noise is mostly caused from the same thing as grain, too little light, or at least that's where you'll usually see it pop up. It generally will just be one pixel, and if there's more than one they usually aren't together. But what actually causes it I semi forgot, something when surrounding pixels change and record they by some means affect another one and usually turns it white.

A trick I use a lot on steadying the cam is to use string. The base of your camera has the screwhole attachment for a tripod, what you do is get a good solid piece of yarn or kite string perhaps, tie one end of the string onto a screw that will fit into the camera. So in effect you'll just be simply attaching the string by screwing it into the tripod mount hole. Then you step on the other end, and the amount of tension from that will greatly steady the camera, then when you don't need it, unattach it and put it in your pocket. Most easy thing to carry around and might help you a good bit.

I was all ready to relax with that solution, but then I went back and looked at all of the pictures i took in that location... not much changed but position.  It isn't there in any of them.  Of course, a cloud could have momentarily occluded it on all but one shot.  But I guess since they were all automatic shots the camera could have had a longer shutter speed for that one shot.

thanks!

I'll try that.  I have a little tripod but it is frustrating to use.  It was a very cheap one.  Even the wind was causing it to shake.  Thanks

It appears to be a lens flare from off camera somwhere. A bright flash somwhere else, a reflection, or even just the angle of the camera may have caused it.

I don't know it there's any connection here, but I saw a documentary regarding the 1969 moon landing, and how many sceptics took anomalies in some of the moon shots to try disproving it. Some of the photography shown had objects which were not visible to the naked eye, but also there were objects that could be seen by the naked eye which were absent in the shots. According to the various experts interviewed, these anomalies are common when photographing the night sky, with or without varying atmospheric conditions being a factor.

Well you'd have the low down on that.....didn't you say someplace else that some ET's had just left your joint for warmer weather.
