But you understand what I am talking about right? Like in Photoshop, there is a live histogram. I have not thought of using Curves+ as a histogram viewer. Thanks!

As an astronomer, I use the histogram a lot. Normally I have had to look at the levels adjustment just to see the histogram while I am in PDN. The problem is that doing that can become time consuming, especially if you are not changing the levels directly. Is there anyway that I can view a live histogram as a separate window on PDN?

Hey thanks for the compliment! As for suggestions, most nebulae should have a really really bright star embedded in the nebula, some don't because of complicated gravitation events. Also, you might be able to see stars through the nebula. Finally, certain colors are more common than others. For example, if there is a star right inside the nebula and it is along your line of sight (see figure A), then you will see it really red. If there is a bright star near the nebula, the stars light will reflect and scatter more in the blue part of the spectrum than the red, therefore you will see it being really really blue. This is the reason why the sky is blue. Other colors like yellow or green will be in wisps because they are caused by the electrons being excited and dropping back down releasing a photon of light at an exact wavelength. Sorry for the long post, this is what happens when I get talking about astronomy.

I ran the alpha displacement plugin on the galaxy without providing a mask. Doing that can make stuff look 3D. After running the plugin at -1 pixel shift on the y-axis, it looked too aliased :AntiAliasingOff:. I decided to run a little bit of a surface blur on it.

Hopefully I can use my knowledge of Visual Basic to learn C# fast enough to improve this plugin without any help from EER.

Well, blue shift is used, and red shift is used, so maybe teal shift can be claimed. I will contact the IAU about that haha.

My laptop mouse scrolly thing does not zoom out and then in returning to 100% or vice versa. Maybe it is just the driver, not the hardware or software?

My original idea of this was to replace the need to have the fill the background black, and then use noise and possibly brightness/contrast.

Hey, you seem to be an expert at these tuts.

It is a lot easier just to get your passport photo taken, and there is no worrying whether or not it is right.

Thanks

I knew plural was nebulae! I noticed that in your tut.

Try uninstalling the old version first. That usually helps.

Hmm interesting, I never noticed that.

That's because it HAS changed. Rick probably coded it in a way that makes a boolean value change from false to true if something, anything is done. If something is done and the actions are undone you can still redo the actions. Ergo, changes have been made and the entropy of the universe has increased!

Ok then. I am trusting you. If the FBI finds this post and sees that we posted here who knows what could happen!

Did you mean to reply to the topic instead of making a new topic?

On the bottom of the windows there is the part with SOME metadata. You can change the size of that by dragging it. PDN keeps the metadata for me, so maybe it is you? I don't know.

I really like your outcome. It is pretty cool.

No prob. Sorry if I seemed harsh, I can be that way sometimes, don't take it personally. Once again, I love your tuts. So far we have an excellent sun tut and galaxy tut. All we need is a nebula (plural being nebulae) tutorial. One that goes in depth!

Hey thanks pyrochild, but there is a problem. When I attempt to save the file, it brings up an error saying: "Saving Not Supported". I appreciate the try, but maybe your dll filetype plugin is not compatible with 3.5.1 There's a bug in Paint.NET involving load-only filetypes. Remove any load-only filetype plugins from Paint.NET, and it should work. If you're not sure which ones are load-only, you can remove all of them. Just put them in a temporary folder and put them back when you're done. I appreciate your help, but EER has got me covered in the stand-alone executable.

I like the addition of the noise, because that would actually happen. The horizontal lines also very true to form. I would recommend blowing the lights (i.e. highlights in the picture) out of proportion when it comes to brightness. Night vision is not a linear technology. It works through the photoelectirc effect where a photon hits some type of metal that I cannot remember off the top of my head and that metal releases electrons. These electrons hit more metal and a cascade of electrons is sent down to a CCD or CMOS chip. Now that is a lot of babble basically meaning that the brighter the object in the picture, the WAY brighter to result will be. It is an exponential regression, I think, it one was to plot it on a grid with the RGB value being a function of the photon count.

True, very true

Jerry, I might have to add this to my sig like I did your galaxy, but I might not. You know, because of night and all. As an astronomer I must correct you on one thing. There is no such thing as a blue dwarf, there is a blue giant, a red giant, a white dwarf, a brown dwarf, a red dwarf, a red supergiant, a blue supergiant, and maybe even a black dwarf. Sorry, it is an OCD thing I loved the tut, and it reminded me of one of the planet tutorials.

I actually did, I have recently changed it to the galaxy tutorial. A rather new tut that is amazing.
