Hmm... If somebody were to program a filetype that reads a configuration file and then automatically sets the attributes of a PNG based on them and does not use a save dialog, then what you are looking for could be done without using .PDN files. You would just have to save them as the other type of PNG. I don't know squat about making file types, but it seems like being able to read a text file rather than making an interface would be really easy to do.

If you are looking for professional photo manipulation, I suggest GIMP. It seems much better suited to what you want. You will find it for different OS's here Though it takes some time to learn it, it is very very useful, and seems like the more hands-on approach you are looking for. Paint.net is made primarily for former MS Paint users, and most solutions to those sort of issues are inconvenient at best.

To be honest, it is best for you to save in the .PDN format until you need to make a final version. It does not have a save dialog, so it is not a problem. Also, it ensures losslessness, it is safer in case of a crash, it is generally faster when saving, and it can be deleted when you are done. Then just "Save As..." into whatever other format you are using. It may be slightly inconvenient when editing an image to create a copy that is a .PDN, but if you're saving it hundreds of times, it is definitely worth your while.

Make sure that the bottom layer doesn't have any special blend modes activated

Those are pro quality, I'd say. Nice work!

I realize this now...Ahh whatever The internet seems to generally like debating about irony, but that's kind of a no-brainer now that I think about it.

Thanks guys! Ironically, this could be done in curves if it had presets. I'd like to see any results of this and get feedback so I could attempt to make another set of curves for something else.

I have put together a collection of vintage-style effects based on actual vintage photographs, for use in making new stuff look older. You can get Curves+ here Download: >>Click Here<< The photo I used was taken with a digital camera, and not modified aside from the vintage effect.

I have an idea that different channels of an image could be supported in Paint.net This feature does not appear to me as though it would be possible as a plugin. I think it would work best this way: there is an extra window, much like the layers one, that shows the channels of a selected layer. It would let you choose whether you want RGB, HSV, LAB, CMYK, or whatever schemes are associated. It would allow you to click on a channel from the list and view only that channel in grayscale, and have all filters apply only to that channel while it is selected. Each channel could be simply deselected by clicking it a second time, allowing you to see what the changes to the channel did to the entire image. Does this sound possible?

For larger images, I think that if they are Gaussian blurred the right amount and you apply the effects multiplied by the resolution of the image you are trying it on, it works just as well. EDIT: I also found that applying a sharpness effect with a large radius makes it look much more VHS'y

You may want to try adjusting the saturation lower in step 9. Otherwise, a black & white image may be the way to go.

Isn't there already a link there? I found the problem, btw. It thinks because of the url that the extension is .png/ rather than .png I'll fix that up...

Wait, no. It appears I can make a post with and image, but I can't edit one to have images

Insert media? It says this is how it should be inserted in a forum: By ssaammpp at 2011-02-09 EDIT: There we go

My PNG's were optimized, why did it say they weren't allowed? This is one of them: http://img46.imageshack.us/i/17final.png/
