Has anyone ever thought of writing on lenses. Example. Take a shot of the night sky's full moon the stars near the moon aren't visible. Put a water based mark over the moon on the lens to 'filter' it out.

Am I being daft?
 
Why? i can't see why anyone would want to, whatever it is your trying to produce on a photo?

This would not work as the image of the moon is not produced from just one localised part of the lens but instead the light is gathered from a fairly large area and then focused ( concentrated) at the sensor) .
To mask off the moon effectively you could try using a black marker pen on your camera sensor at the approximate point where the moon would appear BUT I would advice you most strongly not to thy this out !

It's called a gobo...

Haven't used one since... erhmmm... right! 1977...

Good for longer exposures, cut a bit of cardboard, glue it on a stick, have it fixed, so it covers the moon/horizon/lights/shapes/whatever you want to expose less.
Click the shutter, let the sensor get some lights, remove gobo... will probably require a bit of tests...

Or keep gobo in place and make a second exposure only for the moon/whatever and join shots in post.
 
You could try painting a moon-sized blob on the sensor, rather than spoiling expensive glass. :exit:

Could I suggest that you pick a date where there is no moon in the night sky (ie: dates that have a new moon), then go and take the photos of the stars while the moon is not there.

Also, what's wrong with using Photoshop or similar image editing software, to remove the moon and paint in more stars?

Or you could place a very black, moon-sized object between the Earth and Moon.

Could be tricky keeping it aligned with the Moon's orbit and other people might complain, though.

If you're going to go to the effort of "removing the moon and painting in more stars" why take a photo at all? Just make a black canvas in Photoshop and use noise to make "stars"...
 
I don't want rid of the moon. I was thinkin about get the stars near to it show up more with slightly longer exposure where a full moon would over expose. I might try it on an old uv filter see what happens.....
 
'Salrite - it's solar powered...
 
What about the light given out by the moon (OK, I know it only reflects light) making the immediate area around it lighter?

But the moonlight will always be strong enough to leave a glow around the moon, enough to make any stars near the moon hard to see.

It's the same effect as why most of us would rather drive out to the countryside where there are no street lights so we can see the whole night sky.

No matter how hard you try to block the moon or moonlight, be it your crazy idea of drawing a dot on your lens or other member's silly suggestions about blowing up the moon or painting it black or whatever, the glow of the moonlight will still wash out the stars too close to the moon.

It makes more sense to go out on a night when there is no moon, take as many photos as you want, vary exposure, and all that, get all the views, exposures, frames, etc., of the stars the way you want it.

Then on the night of a full moon, take a photo of the moon.

In photo editing software, like Photoshop or Corel PHOTO-PAINT or whatever,

cut out the moon and paste it on the photos of the night sky with all the stars.
 
But then it wont look right because there'll be no glow around the moon. ;) :eek:

I like the "gobo" suggestion further up myself. Post #5

If you were to blow up the moon, it would probably glow quite brightly for a while, I'll grant you that. :)
 
Do it on a moonless night for the sky, and fuse it with a moon shot from another time
 
You could try it at some point during the full moons on 15/4/14, 8/10/14, 4/4/15, 28/9/15 and with a little less success (possibly...) 23/3/16 and 16/9/16. Although the last 2 could possibly give the result the OP's after.

Ha ha. Very clever. Though some travel would be required on most of those dates...
 
Depends on how much you want it blocked. Penumbral should reduce the glare a fair bit but still have it partially lit.
 
do it in photoshop and stop yourself from unnecessarily destroying a lens. Was probably said many posts ago, but I got fed up.
