GIMP :: Adjusting Color / Brightness And Contrast Of Multiple Layers Of Animation
Oct 4, 2013
What I'd like to do is adjust the color and brightness/contrast of many layers of an animation. Now, for a still image with many layers I know you can generally add a partially transparent layer over the whole thing, however, since it's an animated .gif I have to do the same thing to each individual layer. I could probably go through and do it by hand and just get it over with. But, I'm curious if there's a feature for this, or is there a plugin that can repeat actions for multiple layers?
Brightness/contrast only seems to have an effect on the 'background' layer--not on any subsequent layers I apply. And it only seems to be on the current docs that I am using--if I open some older ps docs from the recent past, brightness/contrast works fine on all layers...?
I'm trying to adjust brightness/contrast and saturation over about 30 layers on an animated GIF. Everything looks great until I do a save for web and click on the animate box. At that point, the color/changes drop off completely. It shows up fine when it's just the one layer being shown. And it seems to be showing up on all the layers when I'm in the main edit window. I keep looking and making sure I have the 'this adjustment affects all layers below,' and I do. I even tried saving a GIF with the other setting turned on and I got the same thing.
Anyway, I exported a few GIFs, thinking maybe the adjustment layers would kick in as it saved, but nope. Neither layer saved into the exported GIF.
I'm sure this is just a simple setting I'm missing, but I'm banging my head against the desk at this point.
I am able to change the brightness/contrast for part of an image by using, for example, the Rectangle Select tool. I want to be a little trickier though. I would like to use the rectangle select tool, but have the effect of the brightness/contrast apply 100% at the bottom of the rectangle and say 10% at the top, with gradations from 100 to 10 from bottom to top. Is this possible?
i have a folder with about 100 jpg files in it that i want to apply a general brightness contrast setting to.
Using the main interface to do each one I would need to go to Tools > Colour > Brightness Contrast and set a Brightness value of 16 and leave the contrast at 0
What i would like to do obvious is to run a batch command to do this operation on all files in a folder
I've tried guessing at a few command lines to do it but all have failed and basically how to do it.
What is the effect or process to, for example, ensure that normally washed out bright background on, say, a sunny beach, has same depth and contrast as the darker subject in the foreground? It is an unnatural state since your eye and most cameras will adjust to one extreme or the other.
what is the best method for adjusting brightness and contrast in CS6? Is it by simply adjusting the Brightness / Contrast properties in an Adjustment Layer or is there a better way of going about it?
It's a small issue, but one that was a no brainer in CS5 - I use Legacy Brightness Contrast about 80 times a day, and CS6 no longer keeps it ticked, I have to manually enable it every single time, and by about the 57th time of having to do this every day, it becomes a more than a little irritating. As some of you will remember, CS5 just kept it ticked once you selected it.
The new brightness / contrast is great for certain tasks, not so great for others. I, and I'm sure many others rely on the legacy version.
I try to apply Levels & or Brightness & Contrast settings to an image, it always seems to revert back to the way it was. The filters won't do anything it seems. I have Adobe Photoshop CS2. At home it did the same thing and I re-installed Photoshop only to find out it still did not work.
'Brightness/Contrast' screen becomes unexplainably absent while using my PhotoShop 7.0 in XP. When I click on 'Brightness/Contrast' the eyedropper becomes active as usual but the dialog screen with the two 'sliders' for brightness and contrast is not visible. Where is it? If I uninstall and reinstall it's OK again for a while.
I'm looking for a plug in which will reduce the brightness (to a level which I can select) of an image away from a central point on the image. Does such a plug in exist.
I have an indoor group photo using flash light. The problem is the center of the picture is much brighter than the sides. Is there any easy way to increase the brightness and contrast towards the sides, and gradually decrease the brightness at the middle?
looking at the image plane and the 2 inputs I used - diffuse / opacity (alpha channel), what parameters are the best way to adjust the image plane brightness / contrast / levels (photoshop style)?
That’s what I like about these forums. A great way to get straight to the point and learn stuff fast.
I'm importing RAW files straight from a CF card reader into my network storage drive via LR5.3. While reviewing as it imports initially each image looks great but a few seconds after it loads onto the screen it seems like LR applies a bit of extra brightness and lessens the contrast and I lose a load of detail that was there originally. I've not touched the import settings and no filters are being applied by myself on import.
I have two images, taken in the same location. Because of slight changes to camera position or other things, they're not the same. The color and brightness are slightly off.
How can I match them? I'm especially concerned about the color.
Every time I use adjustments like brightness/contrast, PSP seems to remember those settings, because the next time I use them, they start with the same values as I used before. But I do not want that. This way I always have to move all sliders to their zero position before adjusting. Every image needs different values and I always like to start from scratch (zero values).
So, how can I tell PSP not to remember those settings every time?
When I have multiple files open, the tabs at the top look like this:
These are roughly twice as large as I'd like them. I've been able to customize virtually everything else (which is awesome!), but I can't seem to find a way to change the tab style here...
So, is there a way to do this, replace the previews with file names, or something like that?
Having trouble with my Photoshop 7. When I want to use the Brightness/Contrast adjustment within the Image/Adjustment section the scroll bars for brightness/contrast do not come up. An eyedropper tool appears. When this happens I can only click on the image and change the color squares on the left in the tools area. I can't even close the image or close the program. I have to Alt/ctrl/delete to close the program. I've also uninstalled the program & reloaded but this problem continues.
I sometimes have to fix up group photos that have been taken with a flash, where the people farthest from the camera are relatively dark. I would like to be able to apply the "brightness" and "contrast" controls to the photos in such a way that the amount of change varies across the picture, in much the way that the "gradient" control works for a color or a pattern.
I imported 100 images (each one on a different layer) in Photoshop CS5.1 to make some image correction. Those images are an animation sequence.
Now, I try to figure out how to play the animation? When I click PLAY, it doesn't move from a layer to another which would make it animate. It stays on the first layer.
I have a long and complicated road trip timelapse photo set I'm converting to an animation. That i've managed to sort out. However I also have some panoramas that i took here and there. I'm trying to take these panoramas (about 11 of them) into their component images,but with an overlap so that they will be in the animation appearing as a pan.
So I have about a dozen of these fairly wide images (2096 x 544 for one of them), and each of these i want to split into about ten images with a reasonable "overlap".
Given the amount of potential images, and my desire to have a smooth pan, making composite images manually wouldn't really work.
I've been using ifranview to bulk crop and resize images but i couldn't work out a way to do this so I switched to GIMP, which I'm not great with.
I've grabbed the guidelines every x pixels script and guillotine into layers plugin, hoping I could guillotine across multiple guideline "units" but all it's given me is dozens of vertical slices of the image.
I could merge and duplicate them but that would take ages.
At the moment I'm thinking my best option is to put the guidelines on and use selections to snap to guidelines and paste as seperate layers, then save all the layers as seperate files. However that still seems very slow and clunky and i'm wondering if there's a better way.
I like having a source and a working image.. so what I end up doing is opening the source, then creating a new image, then copy/paste the layers I want over..then sometimes scale the items, or whatever..
I cant seem to be able to pick multiple layers to copy or scale.. I can chain them and then move em all together ok.. but as for copy/paste scale.. I haven't managed to find where I can group them and copy/scale .
I'm making a .gif image but the video clip frames I imported have an undesirable rectangle at the very end (it's just starting to fade in). So I'm trying to go frame by frame and edit each layer individually to erase the rectangle. I only have a handfull of frames to edit and then I should be good to go but figuring out how to switch to editing other layers has proven difficult. So far if I turn off the top layers when I try and edit the underlying layers it only draws on the top layer. I didn't want to move any of the layers since that would be much harder than just editing them where they already are.
I have a 63 frame animated gif and I need to paste something to all the layers... all I could find is this here [URL].... but the plug in takes me to a page not found....
If I hit copy and then paste it as a new image I only get the layer I had selected. If I merge all the layers down to one, it takes a long time because I have to merge them one at a time. Then I have to undo all those merges to the original so I can still work with its layers, just to make a copy of the image I am working on.
And sometimes I want to copy layers from an image and actually keep them as layers in whatever it is I'm copying them to, and in that case my best option to to select each layer one at a time, copy it and paste it as a new layer in the other image. And this method doesn't always leave the layers lined up properly.
So, Is there any way that I can copy multiple layers?
I've been working on learning Blender and using Gimp to edit textures and the like. I'd really like to be able to create tilaable textures and then clone them onto UV maps (the main cutout of a 3d model.
However, One thing I want is to be able to clone the normal map and the specular along with the UV texture map. This would involve cloning from 3 layers simultaneously in one gimp file to 3 new layers in another gimp file. Is it possible to do this at all in Gimp? It's important that the UV, Normal, and Specular maps match precisely in the new image.
