Change color effect only of part of an image, such as only the left side?

I have an image that is basically a bunch of blue dots. On a keyframe, I want to change the left side of the image to red dots. How can I do this?

Here's another way:
Apply the effect to an adjustment layer, and create a mask on the adjustment layer to define the area that the effect should affect.

When using headphones, only the left side works, HELP?

When using headphones, only the left side works when plugged into the macbook. I've tried 3 different working pairs of headphones and different media types and nothing seems to fix it. HELP?

Hi atgoetz,
Usually this is indicative of a bad headphone jack on the machine end, especially if you've tried three different pairs of known good headphones. Unfortunately there's not much you do to resolve the issue, externally. Considering it's a new machine no sense trying to fix something and making it work. I'd reach out to AppleCare for service on the unit and if it's brand new, possibly arrange a replacement unit.

Why does only the left side of my headphone working after ios6 except in phone calls ?

After i updated my software to ios6 , i realised that the right side of my headphones doesn't work with music player nor with typing, yet it does work perfectly when i am on a phone call so it's not a hardware problem ....

thats what i meant, if the same problem persists on two headphones its the jack, but the fact that one side of the original headphones works makes me think its the headphones. plug the headphones up to the computer and see if they work then

My earphones only work on the left side on Macbook Air (2012)

I don't remember if it wasn't working from before, I just bought a new Macbook Air; today, I plugged in my earphones and only the left side was working (left bud). It also works this way with my headphones and Apple Earbuds. Any ideas?

It could be that they're faulty, or myabe even your PC. Have you tried another pair of headphones on the PC to see if it's the PC that's faulty instead of the headphones?

Analog for 'Change Color' effect

Hi everyone.
All my digital photovideo gadgets incorrectly reproduce blue and relatives colors - they become lighter.
This problem is solved by 'Change Color' effect (in a Photoshop the similar filter works the same way).
But painfully slowly it works without any acceleration. I didn't find any other solution for adjustment of specific color (to make blue with shades more darkly in this case).
Perhaps somebody has any experience or any thoughts in this respect?
Perhaps the single way is the fast processor?
Thanks.

Here's another way:
Apply the effect to an adjustment layer, and create a mask on the adjustment layer to define the area that the effect should affect.

Can anyone tell me why this picture changes color when I try to download/upload it? It is the exact same picture I have taken from the same location. The image on the left is via preview and the image on the right is what is shows like when I try to download it. I have emailed it to myself and it shows fine on the computer and in CS4, but when I look at the download via my phone or on another computer it shows the wonky color on the right. I have checked the color space shows RGB/8 bit. Any ideas why or how to fix it? It isn't with any one specific session.... and I've tried it on both my desktop and my laptop- saved image to an external hard drive and to drop box. I've tried sending the image to canvas on demand, my email, mpxipro, POST editing- all the same result. Please HELP!! What am I doing wrong?

Most of the time you see something like that. The image in question has a color profile other then sRGB. Some image viewers/displayers are color managed and others are not. So the image do not look the same in all of the applications you use. So colors seem to change.
Try converting it to sRGB color and see if then looks the same all around. Also I think PC and Mac displays are set to different gamma something like 1.8 and 2.2
Though I'm colorblind I even see color variations.

My HP color LaserJet 3700 has begun leaving a multi-colored band along the left side of the page.

Now there is a colored band of ink on the left side of the page running from top to bottom. A local tech says the printer needs vacuuming. I am dubious. I have emptied the toner bottle already.

Mine's doing the exact same thing. It's been suggested to replace the image transfer kit but I'm dubious....that part is rated for 60k pages and I have less than 17k - ?

On FaceTime contact are on the left side of the screen...they use to be on the right side much better how do I change this listing to the right side?

FFace time contact listing are on the left side of the screen they use to be on the right side...why the change and how can I change the listings to the right side?

There doesn't seem to be a setting for that. As to why Apple made the change, only they would know.

The new itunes overfills my window. When I try to move it to the left so that I can use the slide bar on the right, part of the left side of screen is not visible. How can I fix this, please.

The new itunes overfills the window on my desktop ( windows 7). When I move it to the left so that I can access the slidebar on the right, part of the left side of the screen then disappears. How do I correct this?

The problem of tracks becoming de-linked between iTunes and the music files in your iTunes music folder happens for different reasons - this seems to come up fairly commonly in this forum.
The solution can be to locate each song in the iTunes library, as you mentioned - or, but wait, before I get to that...
trouble finding the original track in your iTunes music folder? maybe look for it under compilations, or if not using the 'group compilations preference' then look in the folder under the songs artist name, but what song artist name iTunes uses depends on what you have in the metedata tag spot for album artist or song artist. Any varyation in artist name spelling, in the menu item 'get info' metadata for any selected individual track will cause iTunes to create that as a separate artist folder in the library, even names like 'various' or any difference at all (even the word 'the' can change where in your iTunes music folder a track gets placed by iTunes). You can try to use the finder function of find file (finder munu item outside of iTunes) to locate hard to find items.
Back to how to re-link any de-linked tracks .
There may be scripts that can help re-link de-linked music files - or, at least provide you a list of such files, Scripts are easy to install and use...
at Dougs Scripts, there is one called iTunes Track CPR that might work
http://dougscripts.com/itunes/scripts/ss.php?sp=itunestrackcpr
or, if you just want a list of de-linked tracks, go to
http://dougscripts.com/itunes/
and find the script called List MIA's, this will create a text file listing all de-linked tracks

The bookmark tab went from the right side to the left side. I did not change that. what cause the change from the right side to the left side?

The bookmark tab went from the right side to the left side. I did not change that. what cause the change from the right side to the left side? Also the the Mozilla Firefox tab on the upper left hand corner changed.
Its was a red colored tab and now its blue in color. I did not change any thing!

Hey jimmiet,
There were some recent ui changes around the downloads manager. What version where you on before? Anyway, you can customize things in Firefox really easily. Take a look at [[Customize Firefox controls, buttons and toolbars|this article on customizing Firefox]] for details. Should be a piece of cake to move the bookmarks button.
As for the color of the button, you might be in [[Private Browsing - Browse the web without saving information about the sites you visit|Private Browsing]] mode. That changes the color of the button from orange to a purplish color.

I am in my e-mail and a keyboard came up but only the left hand-side of the keyboard and I can't get rid of it, any idea how to make it go away?

Have you turned the phone off? If so, and it hasn't fixed the issue, try a reset:
Press and hold the Sleep/On/Off button and the Home button at the same time for approximately 10-15 seconds. Ignore the slide to turn off indicator, and wait for the Apple logo to reappear. Release buttons. No content will he changed with this process.

Audio only on left side

I've seen lots of threads on this and the usual answer is to make sure you click the input as a mono track in order to hear/monitor in both left and right sides in the headphones. It doesn't seem to work.
Have Mavericks w/all updates and gargeband 10.0.1
I have a Tascam US-144 MKII audio interface.
Guitar plugged into channel 2 input (instrument input).
Mono on switch is set to on (turning it off makes no difference.)
In garageband, I have a guitar track set up.
In info window... Input is set to Mono channel 2. I hear the guitar only through the left side.
Changing this to a stereo input or back to mono does nothing. I assumed that it being mono I'd at least be able to hear it in stereo through my headphones.
No?
If I record like this, will it only record w/a hard pan to the left even though pan level knob is set dead center?

Problem solved...
Even though I had everything set up correctly, I was using an incompatible jack adaptor on my phones. I substitued it for the correct 1/8 to 1/4 adaptor and it sounds great now.

Logic won't let me record stereo style! Only the left channel.

I was recording just fine with my keyboard connected to my TASCAM US-122 USB interface with an instrument cable today then all of the sudden I could only hear the keyboard in the left side of my headphones. I tried the other line-in and then I could only hear myself on the right side. What went wrong here? Keep in mind, it was working just fine but in between takes it cuts one side out. And all of my pan adjustments are equal.

If you are using a single, jack to jack cable you are effectively recording in mono, on one channel. When you are monitoring your recording signal you will only hear one side because your tascam is only sending it to one logic channel...
Your tascam has a mono direct monitoring switch - you should switch it on when recording with only one jack to jack cable - it will allow you to monitor directly through the interface whilst hearing your sound on both sides. You should record to a mono logic track and you will then be able to pan it afterwards as desired.
For a true stereo keyboard recording you would need to connect two jack to jack cables from your keyboard (if it has left and right outputs) into two separate mono channels on your interface. You could then record to a stereo track on logic, or two separate mono tracks panned hard left and right.
I may be wrong, but I reckon your problem stems from not properly understanding how the stereo field corresponds to recording channels.
