Yay, first to download and comment on it!

:o This plugin is great!! Thanks BB! Have a and chill for a bit.

[BoltBait 2,334]

Heh. You offer me a when I already have a ? :shock:

[Ash 10]

Thanks!

Um does the Source Code work for others? I get some errors. (In Codelab)

[Code_Ember 0]

Thanks for the automated process for my tutorial!

Heh. You offer me a when I already have a ? :shock:

And BoltBait, my friend, that's called Alcoholic Dew!

Do you people have a secret community for making plugins that do the work of a tutorial?

Thanks for the plugin BB, I liked the effect from the start

I think BB was using a "newer" version of Codelab which he hasn't released yet

DLing. But the kitty has part of his ear missing

Yeah, sorry. I'm still working on CodeLab 1.3 and hopefully it will be released very soon.

Glad you all liked the plugin, though. All credit goes to the author of the original tutorial. 8)

Not that it matters to me but,

Lomography is the commercial trademark of Lomographische AG

I'll use it, thanks.

Great plugin.

Great plugin.

Notice Simon Brown put in the ™ in his reply title. :wink:

Perhaps I should change the name to "Lameography". What do you think...

[heythere 0]

Hope you aren't trying to imply that it's lame. :?

Great Plugin Boltbait, but the result is a little heavy dont you think, could you possibly adjust it (mabye i'm asking too much) so that the whole picture becomes really dark and hard to see. I'm forced to use the tutorial instead.

EDIT:

Great plugin.

How did you even notice that? :shock: :shock:

I tend to notice everything, especially ™ signs (which is kinda weird.)

[crimsonsorrow 0]

first added glow and then lomography. awesome effect to mess with!

Lol i notice the green guy in your post title.

Anymoney you just looked at my post title

[Possum Roadkill 7]

I knew I would finally use this. I used it on my album cover in the Alfredo section. NOW I UNDERSTAND IT ! Oh sorry I didn't mean to yell.

[Remii9512 0]

Awesomeness.

makes an epic effect, keep it up!

[crappy 0]

May I ask why I cannot access the tutorial on how to create lomography effect anymore?

:(

[Frontcannon 7]

That's a legacy tut, ask a mod if you want to see it again.

Would it possible to add an adjustment on the Vignette, Brightness and Saturation. As with some/most images, the effect is way too dark in the center. And, the Lomo cameras have a higher than normal saturation, not darker. That's why I think a Brightness adjustment is needed.

It can be adjusted with "Curves+", and the saturation can be adjusted with the Hue/Saturation+" dialog. But, it would be nice to have it one dialog, since PDN doesn't have a way to memorize multiple adjustments as a "preset"

I second this one.

Great plugin, though.
