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?
View 4 RepliesI'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.

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?
How to do this all at once. I did something similar a few years ago, but can't remember enough to even get myself going ?
View 2 Replies View RelatedI 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.
When I save my renders in 8-bit tiff formats, the images are slightly blurred. They do not look as crisp as in the render window.

When I create a new RGB image with 16bit there are only 8bit values (0-255 and not 0-1023) in the color picker and in my info panel.
Is PS CS2 just working internally with 16bit and doesn't provide manual access to all values?

I scanned an image using Image Capture which turned it into a tiff. I opened the tiff in Photoshop and discovered that Filter Gallery was grayed out.
I opened an older Photoshop tiff and looked for differences. The older one, wherein filter gallery was available, was an eight bits per channel document. The new one is 16 bits per channel. When I changed the new one to eight bits per channel, Filter Gallery became available.
If my (extremely limited) understanding of the technology is correct, there is more information in 16 bits per channel and hence presumably a richer quality image. On general principle of course I'd prefer not to lose any richness. Is there some way I can get Photoshop to give me access to the filter gallery in a 16 bits per channel mode?
I've used photoshop to paint for many years (I'm a production artist for children's television) and never had this kind of thing before. It could be a total coincidence, but it seemed only to get like this since I upgraded to Production premium CS6.
I have the newest Nvidia drivers, the latest photoshop and production suite updates. I've tried turning off GPU acceleration and I've calibrated my monitors and cintiq several times using the Spyder 3 Elite calibration tools. I've created 8bit, 16bit and 32bit images and the problem persists no matter what. Other stats:
Adobe Photoshop Version: 13.0.1 (13.0.1 20120808.r.519 2012/08/08:21:00:00) x64

This is a 16bit image saved as a jpeg, but still a relatively accurate example of what I see in photoshop. In fact it looks better here. It was created using a low opacity brush with hardness set to zero.
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.
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?

View 2 Replies View RelatedI'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!
View 2 Replies View RelatedMy 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'm currently working on a User Interface for a Wall Panel, but this Wall Panel has only 16bit (65.000) colors, i've tried a lot of different things but can't find a way to get smooth gradients, my images always have gradient banding.
I was wondering if there is a way to tell photoshop to work in 16bit mode ? (not 16bit by channel) so that the colors selected for the gradients would always be contained in the 65.000 available colors.
For the moment, the only way to get a 16bit image is when saving a file as a bitmap and selecting 16bit. But everytime i do this, gradient banding immediatly appear. Maybe photoshop bitmap encoder is just not that good for 16 bit mode bitmaps .
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.

View 3 Replies View RelatedI noticed that when I open a 16bit ppm in GIMP 2.8, the file opens without the 'gimp can't handle 16bit, it will loose data, etc...' notification. But if I open a tiff version of the very same raw file, the notification does pop up. My understanding is that current GIMP 2.8 can't handle 16bit, regardless of file format. Is that right?
View 6 Replies View RelatedI have a series of PNG images which have been authored from various sources, but mostly with Gimp. The images have transparent backgrounds and use partial transparency effects like drop shadow, etc. I want to display these on a bitmap layer of the TImage32 component from Graphics32.
I have dropped a TImage32 component onto my form, with the intention being to set the visibility to off, and use the TImage32 as a container for the PNG image I want to draw on the layer.
When I go to load the image at design-time, the dialog has two tabs - it allows me to load the RGB image, and the alpha channel, and I don't know how to produce these - I prouce the image by using the export to PNG function of Gimp. If I load the exported PNG into both the RGB channel and the alpha channel the resulting image doesn't have the transparent background. There obviously must be a procedure I need to follow to get Gimp to produce both the RGB and alpha channels.
I recently noticed that Channels-settings in both Group Properties and Blending Options are lost when changing a file from 8bit to 16bit and vice versa.

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.
View 18 Replies View RelatedThis week we are working with 16 bit DPX. We import that material into the media library as 16 bit float with the 16i_to_16f color transform. That media then goes on to a 16 bit float timeline. We then have to add a 16f_to_16i to get the image looking ok on the monitor again.
We seem to be having an issue when performing a resize on the material. There ends up artifacting around the hightlights. Changing the filter and filter values seems to have a better visual effect, but we're concerned that we are effecting other parts of the image.
Is there something else we should be applying to better map the values on the highlights?
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...
I have just had to do a complete re-install of my CorelSuite X4 following the addition of a new hard-drive.
I now have the situation in Corel Photo-paint where -
1 I open a grey-scale image (.jpg).
2 I paste (as a new object) an RGB colour item (a previously created .cpt file) onto the grey-scale image.
3 I then "Convert to 16Bit grey-scale" in order to change the whole new image to grey-scale, but the pasted object is being automatically flattened into the image and I can no longer work on that object independently.
I never had this before, as I was always able to convert to grey-scale and the "pasted object" would remain with the mask outlined and still allow me to work on it.
I wanted to use the program to design a robot for our school vex competition. Vex has provided cad files for all the parts. So, how i can import the seperate parts into one design. I can only open each part individually but cant find a way to combine them so can assemble the robot in one design.
