Steven-
Do you use a IR or UV filter with your web cam? Great image also.

Thanks

Helix Nebula

Hi Mark-

Hope you don't mind but I played with yours a bit. There were some gradients and I brought out more color with PS7. Let me know what you think...

Hope you like it

Helix Nebula

Posted By Carl Burton

Mark-

In PhotoShop:
1 Image|Adjustments|Curves This brings up the Curves box. If you put your curser on the part you want to highlight and press Cltl it shows where that area to highlight is on the line profile. I used 42 (12 o-clock on the Helix) and used my up-arrow to get 97 in the output box. You can see the gradient pretty good now.
2. Image|Duplicate
3. Select the copy. Filter|Noise. I used a raduis of 13. You are trying to get rid of stars in this step.
4. Still in the copy use the Stamp tool with a Brush diameter of 300. Put the circle outside the nebula at about 2 o-clock and push Alt move to cover 1/3 of the nebula with the circle and left click your mouse. Do the same to the other 2/3 until the nebula is covered over.
5. Still in the copy Filter|Blur|Gaussian Blur radius of 48 Now you are trying to blur the heck out of the image and smooth the stamp tool work.
6. Go back to original then Image|Apply image try Multiply or Subtract. If you use Subtract you have to make the copy the source in the dialog box.

That's pretty much it, if I can help just post your e-mail and I'll get back with you.

First Attempt at Saturn

Derrick-
Can you tell me what settings you use as far as f-stop on the camera and gain?

I use Iris so I'm searching for camera settings.

Thanks
