got excited, downloaded, shows up under Filters->error messages?

noobie here very excited about trying out this plug-in! =) put this in the plug-in area of my gimp install and it shows up just fine in the Filters menu buuutttt....

when i tried it on a picture, i used the settings that opened up in it ie, layer opacity 95.00. when i clicked on OK, it simultaneously gave me two warning messages:

1. dynamic range increase message
error while executing script-fu-Eg-DynamicRangeIncrease
error vector-ref: out of bounds 1

2. GIMP message
Plug-in 'Dynamic Range Increase' left image undo in inconsistent state, closing open undo groups.

gimp seems to have closed the plug-in with no effect upon the picture - i can still edit it just fine but without using that plug-in. any ideas what's going on here? i'm using windows 7 - hope that's not the problem. thanks in advance for any available help. =)

Do you have something

Do you have something wrong?

script-fu-Eg-DynamicRangeIncrease is not this script. Mine is hdr-eff-plus.scm

and is not on Filter. It's registed on : /Script-Fu/Enhance/Fake HDR Effect plus...
and /Script-Fu/Enhance/Fake HDR Effect...

You have to check what's script-fu-Eg-DynamicRangeIncrease script is. Where you download it and ask the author how to fix.

Sorry! I can't help you

I have downloaded this

I have downloaded this script, but it will not show up in the Script-Fu in GIMP. I placed it in the scripts folder, do I need to be placing it somewhere else?

Do you place it on the wrong

Do you place it on the wrong dir? Please recheck

It's on right script-fu menu with the same level with files, filters... menu

Does anyone know how to fix the script-fu error with gimp 2.6?

Error while executing script-fu-fake-hdr-effect-adaptive:

Error: eval: unbound variable: plug-in-ace

I've tried all the variable setting ideas from googling fixing script-fu's, but I just don't understand scheme well enough to get the idea of how to do it.

TIA,

Jim

Wrong Script

You're referring to the Fake HDR Adaptive script. Have you tried deleting and downloading the .scm file again? (Just in case you didn't undo any potential typos.)

Fake high dynamic range effect for Gimp

i like a lot the output ,especially in your examples nice script But i found script name misleading HDR , true or fake do not boost the colors as in your examples and in that on tutorial page Maybe something as Color-boost-HDR or Technicolor-HDR will describe better the effect (is not needed to add "fake" all hdr scripts for gimp create fake hdr since the real requires 16bit )

16 bit??

Why does it require 16 bit?? In fact what are you talking about? HDR simply stands for high definition range. it is a technique where you combine the highlight / lowlights from underexposed / overexposed images with an original normally exposed image to improve the overall image. You are clearly an idiot Please go and take a long walk off of a short pier so as not to contaminate the gene-pool

16bit??

Clearly Anonymous you are the fool. A simple correction rather than a tirade of insult would have sufficed to get your point across. The suggestion to walk off the end of a pier is also a clear indication that the only thing functioning between your ears is in fact one gene. To clarify the point, to create an accurate HDR you do in fact require multiple 16bit or above images. Richard

HDR?

HDR does not stand for "High Definition Range". It stands for "High Dynamic Range". Definition would refer to the number of pixels per inch in the image. That is not affected in HDR. Dynamic range refers to the difference between the darkest and lightest areas of the picture, not the number of pixels.

HDR?

Real HDR require as imput images at 16 bit. What you call HDR is tone mapping aka FAKE-HDR that may be done also with 8 bit images .

The reason why they use 16

The reason why they use 16 bit is that they can record light levels far above what your monitor can display at max brightness(like the sun), and far below what it can display when its off. You could hypothetically use something with more or less bits, but you would start to see the larger gap between the shades if you used too small a number, and it would become more noticeable. I agree that this is more like tone mapping.
