And another from my adventure the other night. You can just make out the Southern Cross & the 2 Pointers.

Yes, I know, I have to fix up my Horizon ( How do you do this by the way )

Mic. :wink:

Go into photoshop. Turn on gridlines. Select all. Then in the transformation section do rotate. Then just place the cursor in one of the corners and spin the image/marque until the horizon lines up with the gridlines. Well that's the way I do it :)

Or you could go to the ruler icon and measure the horizon, i.e click on one end of the horizon then drag the curser across to the other end of the horizon then go to the rotate image menu and in the free rotate option (cant remember what it's called) your rotational angle will be automatically be entered to give you the perfect level horizon.

Please Explain ?

Why does the Horizon do this ?

Because of Wide Angle Lens ?
Or
Something else ?

Thanks,

Mic.

The obvious answer would be that the camera is not straight :roll:

After using the Measure tool (the little ruler found grouped with the Eyedropper Tool) to define the horizon, click on Image/Rotate Canvas/Arbitrary. As Paul said, this will automatically calculate the correct adjustment angle and save you OH SO MUCH frigging around trying to get it right yourself!

:D

Thanks Simon for the tip. Very helpfull.

Sirhc55, If I have not got it straight, wouldn't the Rocks look not level if I correceted the tripod to match the Horizon ?
I thought I had a pretty good eye Hmmmmm :roll:

Do you know what I mean ?

Thanks,

Mic.

The rocks per se have no definition with regard to perspective - the only thing that has a known perspective is the horizon line :idea:

I've learnt something here ...

Thanks all you wonderfull D70ers !

Thank you for that advice about how to straighten up the horizon.
(measure tool etc ...)
It really saves heaps of time compared to what I was doing before.
I'm not going to mention it, it is too emberassing.

Cheers

Thats great CD,

Now I know why I did it.

Climb a mountain, get swooped by Mutton Birds at Midnight, fall down Mutton Bird Nest holes, suffer severe soreness, stay out till 1am on a monday night.
And end up getting a crooked Horizon.

At least I can rest knowing I helped a few D70 Users.

Cheers,

Mic. :D

Here' another easier way to do this using Nikon Capture (IMHO) 4.2 (the new update).

  • Choose Image/Rotate/Straighten
  • Click the Draw Level button
  • You now have a tool that let's you draw a line on the thing you want to be horizontal
  • Draw the line and release the mouse button
  • The image will now rotate so the horizon (the thing you drew the line on) is straight

Thanks Stubbsy :wink:

Haven't got Capture.

Thanks anyway.

Mic.
