16-bit photoshop filter

I just started looking to develop filters for photoshop and just watched the sample invert filter.

In looking at the code and experimenting a little impression that 16-bit mode (RGB) uses only 15 bits (0 - 32768) for each layer is this correct?

In the FAQ:

3.3.1 why my 16-bit plug-in only see values 0 - 32768 and not 0 - 65535?

Photoshop uses an internal representation of the data 16 bits 0-32768. During the acquisition, import, reading, or writing files check or set the maxValue in save the settings. The filters will also see this range for 16-bit data.

  • What is the difference between CC 64 bit Photoshop and Photoshop CC 2014?  I think I have them both on my machine

    When I'm in Lighroom and click on change in and Photoshop select the option I get is Photoshop CC 2014.  However, the program that I have pinned to my taskbar is CC 64-bit Photoshop. What is the difference?  I guess that CC 64 bit is the most up-to-date or is it.  How can I change that Lightroom allows you to edit photos?

    Thank you

    I don't want to lose all my 32 bit plug-ins I've bought over the years. I noticed that a lot of software vendors only offer 64-bit programs now.

    32-bit plugins do not work on 64-bit Photoshop. However, you can download the 32-bit version for this purpose.

  • updated 32-bit and 64-bit Photoshop

    Hello

    Today, I use 32-bit photoshop in addition to 64-bit because some features are not available in 64-bit.

    To December 18 photoshop downloaded the update to 12.0.3 and installed.

    The 32-bit version of photoshop that I installed today is just the version 12.0. How can I update? The program told me that it is not updated.

    I tried the manual update, but it failed.

    What should I do?

    Sincerely,

    RazooN

    You will need to uninstall properly and possibly manually remove the databases (records OOBE, caps.db), and then reinstall from scratch. This is a limitation in how signatures updates apply to a 'product', not two separate versions of the same product. Yet, shouldn't be too complicated. CS5 installers are fast enough...

  • Question of the old Photoshop filter

    I have several old plugins (8bf files) I want to use with Photoshop CC.  I read that they had to be in the 32-bit plugins folder and they would be present at all in the 64-bit, so I made sure that was where I put them, but when I run the application Photoshop (either version) appear not the plugin for.  Am I missing something?  I went through all the menus and couldn't find anything that suggested a way to import or even to point to a directory for them.  Any help would be appreciated.

    Unable to understand why this has not been answered, I only came across it looking for information on a set of filters .8bf that I installed a few years and who works suddenly inexplicably fails to work breaking 32 bit PS CC - note that it's the same setup, I had the habit of PS CS5 Extended. Actually, I uninstalled (removed completely) the filter now does not work, stop (cold start), kicked upwards and checked the filter no longer appeared in 32 bit PS CC, after having checked that it was not, I close the program and extract the files from the zipped copy I have directly in the same folder location as before that was empty Open 32 bit PS CC again and it showed, tries to use it once more failed with the same error as before. Note that the PS CS5 Extended uses the same file and I tried to use there after the failure of the last, it worked without any errors.

    Anyway, your answer is here-

    I made a folder on the drive C itself, (not in Program Files or 32-bit Program Files) I named the Plugins folder, inside I put subfolders for each filter I have install and install directly to them, I often leave a copy of the file extraction (.exe) or zip inside as well as its implementation of the files or .8bf. -You then have something like this... C:\Plugins\screen... C:\Plugins\Redfield... C:\Plugins\MasterBlaster... etc.

    The value of PS to locate this folder as a Folder of plugins additional location under «Edit...» Preferences... Plug-Ins"inside of the PS itself, choose" C:\Plugins\ "in this folder by using Browse button if my own example, select your own folder, if you change the location."

    Note: Photoshop offers only an additional location for Plugins/filters (other programs offer more).

    The benefits-

    You can uninstall Photoshop and your plugins/filters are installed (takes time if you have many-to-install) reinstall Photoshop and set the location again and your filters work.

    You can access filters by using another graphics program
