Photoshop :: Linear Mode Different In 32bit Than 8bit?
Apr 5, 2012
We are rendering raster passes in cg which need to be added together to reassemble a beauty render.The layer blending mode being used is linear dodge.There is a dramatic difference in the result in 32bit mode compared to 8bit mode.We normally work with adobergb1988 color workspace.
What is the math being used in 8bit mode with the adobergb colorspace?The problem is similar with sRGB profile.If set up a linear color workspace icc the 8bit mode behaves just like 32bit mode.However no one in our facility nor our clients wants to work with a custom linear icc profile.I would like to preprocess the layers while in 32bit mode to compensate for the gamma space processing of sRGB or adobeRGB color profiles in 8bit mode.Ive tried simply using a exposure node with gamma 2.2 but this is clearly not right.

I removed my nVidia Display drivers in safe mode and reinstalled, the problem persist. I reset my PS settings... same problem.It works only in Photoshop 32bits.

I am using a windows CS6 Bridge => Camera Raw (8.2) => CS6 Photoshop (13.0.1 x64) to try to open various 16-bit raw files (.dng, .nef, .arw) which Bridge sees as 16-bit, but only an 8-bit version makes it into photoshop.
How do I convince Camera Raw to do its job?
Lightroom (4.4) is able to export a 16-bit .psd which sort-of-works but shouldn't be necessary.

How do I change to 32 bit mode in CC using mac OS 10.8.5? The "get info" pane no longer has the 32 bit mode option.

Simply adds the two components. But this is only correct if there is no transparency involved.
Once there is transparency involved, it gets more complex. So, what is the math behind the linear dodge blending mode if the top layer has semi-transparent pixels (=alpha less than 1)?

I ran MacKeeper the onter day and it actually fixed all my woes, however, when I went to open Photoshop, it only opens in 64bit mode. Could be a coinsidence.I quadroople checked that it is selected to open in 32bit mode in the "Get info" window and rebooted many times, but I can't get Photoshop to open in 32bit mode.I was hoping that there is something I am missing before I have to reinstall.

I am booting up PS in 32 bit mode so I can use the Lighting effects but I am still not getting the option in the render menu.

Most of the posts I have seen about this related to mac and I am on a Windows 7 machine. Required for importing video as layers (or as least Photoshop told me so)

I'm working on an edit, which is in video mode. Now I have to include OpenEXR material, which is in linear mode. How can I combine the two and still have the correct color?
I can set it in view mode to linear, but then all my video shows as linear too, plus, as soon as I leave the view mode, it all goes back to video, and my EXR's are too dark then..... what can I do?

There is no crash report. With Bridge CS5 everything works fine. (Opening RAWs with minibridge CS6 works file too.)

I'm trying to edit some scans of some drawings in Photoshop CS3, but I can't edit much. I think it might be a 16 bit TIFF, but I can't change to 8 bit. The option is completely grayed out, along with many others.

When I use the 8bit mode in PsCS3, I notice some banding when using tools such as gradient map.When using 16bit mode, the banding is not so noticeable but it seems to increase file size.So which bit mode should I use for creating images for the web?

How do you convert the photoshop cs file that is cmyk (I think thats the abbreviation) to 8 bit RGB so you can edit it in imageready?

involving the choice of creating a new image with 8bit or 16bit color depth.
If I'm about to create a new logo or image of some sort my first impulse is to use the highest of the 2 (8 or 16).
I know it has to do with the amount of color information in each pixel so I grab at the highest number... is that impulse reasonable? Striving for the highest quality? Or is there a point of diminishing "perceivable" results?
I have also noticed that some 3rd party filters do not work when in the 16bit mode so that "might" be a drawback I suppose.
Also - I can set my monitor to 32bit color - and do - yet PS stops at 16bit... what is the reason for this please?

I've read all over that the filter only works with an 8bit/RGB file, which my file is, so I don't understand what the problem is. I am attempting to light a smart object (3d bevel and extruded text) that I created in illustrator, and thought that I might just need to rasterize the smart object before the filter would work, but even after I render it and or flatten the image, merge visible, I still don't have the option to use lighting effects!

My normal workflow consists of opening RAW files in ACR, making adjustments, then moving on to Photoshop where I apply retouching and build clipping paths. I then save the file as an 8bit TIFF. I rarely reopen these 8bit TIFFs again, but when I did so recently what I encountered was not what I expected.
My Photoshop (CS6) is opening 8bit TIFF files as Camera Raw when selected by "right click" followed by "Open with Photoshop CS6". I remember being able to open 8bit TIFF files directly in Photoshop, but I think this change has occurred since installing CS6.
Again, files in question began as 16bit Raw files, but were worked on in Photoshop CS6 (retouching) and saved with clipping paths. This would reduce them to 8bit files. When placed in page layout, clipping paths work properly, confirming that paths are intact.
When I want to open the files again - say from Bridge or a Finder window - by the method "right click - Open with Photoshop CS6", the file is opened first in Camera Raw, and then in Photoshop, and the path(s) is missing.I can open these TIFF files and access Paths but only if I locate and select the file from within Photoshop (File/ Open.../). The Open window gives "Format" as Camera Raw (which it isn't, having been saved as 8bit file). If I override format to "TIFF", the file opens with clipping path shown.

I am using Photoshop CS6. I am unable to save a 8bit tiff or psd file as a jpeg. When I choose JPEG format .iff is attached to the file. When I open the same file in CS5 it works correctly. Whichever format I attempt to save as it selects the suffix for the format above. I have downloaded again but no change.

I just purchased a copy of Elements and have never used it before. Most of my features (such as layers etc) are grayed out. However, my "covert to 8bit/channel" option is grayed out and I can't work out how to choot in 8-bit or how to covert my 24 bit photos to 8-bit.

I finished editing my panorama in adobe photoshop elements 11 and want to add a filter to it, however, the filters are all greyed out. Not only that, but the 8bit/channel option is also greyed out. The picture is RGB/8.

I would like to create seamless greyscale patterns in AI CS6 by using typical Vector-Tools, Gradients and Transparency.Output however needs to be 16Bit/Channel RGB - 256 greys are clearly not enough on the Gradients, they would lead to nasty artifacts in the intended field of use explanation here.I realize that AI is 8bit and that internal Image-Conversion from Vector clearly was no option.The underlying question for me is - does AI also internally work with just with 256 shades of grey in its gradients too?Or was there theoretically a way to pass smoother Vectors over to PS which in contrast to AI can save 16 bit Gradients?All I tried thus far (importing AI though Clipboard as Shape-Layers/Smart-Objects) yielded unusable results for what I'm after.

I have been finding some strange issues exporting out of Sp2 and now still the same in ext1. I set up some color bars and exported HD YUV files in 8bit and 10bit and found there to be a big shift in color and gamma when viewing on the waveform monitor (both smoke's waveform monitor, and an external waveform monitor on my reference OLED screen)Ive attatched screen grabs of the differences when ive imported the files back in and put them in a timeline.
The original internally generated color bars and the exported 10bit uncompressed file are the same but both uncompressed forms of 8bit (2vuy, and yuv2) are completely shifted - and it is not a YUV headroom issue.
When looking at the waveform you can see the steps in luminance seem to be very different - as though the RGB to YUV or YCbCr conversion has been done with a different calculation. Maybe the SDTV BT.601 vs HDTV BT.709 calculation. Gamma is not being shifted as shown by the gradient I have running accross the frame being mapped as a straight line 0-100 in the waveform.
Most other forms of an 8bit YUV file ive tested dont have this issue ( h264, DNxHD mxf's, xdcamHD422). Also ProRes of all flavours is fine, although these are 10 and 12bit.However I have another issure with exporting XDCAMHD422 files in that the length of the mxf is always shorter by 2-5 frames. This is was something I reported as a bug a few months ago and it still isnt fixed.Frustrating since this is the required format needed to supply TVC's to the TV stations, and the most common export function I would use from smoke - although its useless, still...

In the Printer Settings drop down menu both Color Mode and Print Mode are grayed-out. This just happened I cannot think of anything I've done differently.
I'm using OS 10.6.8 and the latest Epson drivers for the 3880. I have re-installed both PS and the Epson drivers. If I print from Acrobat Reader everything seems to work fine, this only is happening in Photoshop CS5.

I am having all sorts of trouble with my setup - 32bit windows 7 and 32bit CS6. I have a 2TB hard disk (with 1.7 unused) and 8GB Ram installed.
I understand that this setup has a maximum amount of 1.7GB ram available to CS6 and this may possibly be the problem. (see the attachment)
My D800 NEF images are around 40MB each. I get out of ram messages in Photoshop and the same in Bridge. In Bridge the 100% lupe takes forever to activate and eventually after several images it says the 100% lupe is unavailable. If I purge the cache it is OK again for just a few images. There appears to be no problem with smaller files, jpegs etc.
I will change the setup to 64bit CS6 on Win7 64bit if this is the only way to rectify the problem.

Now that I have CS4 running on XP I'm trying to do some real work with it. First thing I do is disable tabbed windows and other new features as they have yet to prove themselves useful in my workflow. Perhaps I'll grow to appreciate them. But for now I'm just trying to get the app to work with the good ol' floating windows.
1) Can I stop new images opening with a Window that's glued to the top left corner of my screen? Past versions of PS just opened a floating Window. CS4 obliges me to 'unstick' the Window from the top left corner every time I open a new image. I've scoured the preferences but have yet to find any way to turn off this feature.
2) When grabbing the top bar of an open image window to move it on my screen I find it to be sluggish. With previous versions of PS one would grab the top of the image window and move it quickly on your screen to wherever you want. The response was pretty will instantaneous. With CS4 there seems to be a very slight lag whereby the move is occurring slightly behind the cursor moving it. It's not a huge lag. Just enough to get the sense that there's something amiss. I'll try it in Vista64 to see if the same thing is occurring there.

In the ACR forum, there was a recent discussion about linear segments for the shadows. These are official for sRGB and ProPhotoRGB but are not part of the aRGB specification, but a slope of less than 32 is allowed in the shadows for raw converters and is used by ACR for all three of these spaces.
Does Photoshop currently implement a linear segment for these color spaces and does it make that much difference in practical photography?

before the latest updates to photoshop CC one could export from LR a series od Raw images to HDR Pro, create a 32bit file, save and editin LR or CR.
Now, when creating the 32bit file photshops promts a button for edting in Camera Raw instead of the usual "create file" (then to be saved and opened in LR). Which is ok, but if I edit the file in CR and then open it as a Tiff in LR the adjustments done in CR are not visible in the sliders, but not only, the images is of bad quality in LR.
