Pixel Count In Histogram

Hi,

I would like to see pixel values of 16-bit TIFF images in Photoshop CC2014. I'm able se 8-bit (0-255) pixel values using he histogram and info tabs but it seems that when 16-bit images are opened the pixel values are still displayed from 0-255.

I want to do to see this information for scientific purposes, not for typical photo editing. I've read many discussions about the practicality of editing 16-bit images but would like to avoid having my original question overrun by that discussion here. I am specifically looking for differences between pixels with more resolution than 8 bits.

I found one recommendation t check a box stating "show pixel values in 16-bit" or something like that but I have not yet been able to find the checkbox.

Thanks for any help.

I have a 16 bit image which , due to raw pixel values, appears mostly black when first imported into PS. I can use auto contrast to stretch the image and to make edits, however this changes every pixel value. Is there a way to edit a stretched image then revert back to the original pixel values? I need to maintain the raw pixel values, as these are data I need to use for calculations. I saw one suggestion about using an Adjustment layer then cloning pixel values, but the adjustment layer will not stretch properly to see the image. Any suggestions?

I have several images in different layer in PS3 ( macro images with different points of focus).
I have aligned all layers ok, but when trying to blend the layer (all layers selected) using the auto blend layers tools, the tool does not give me the stacked images button.
Instead it launches straight into the process.
The results are not what I am expecting, each layer bar one has a totally black mask, and the image is not a blend of all the images.
All tutorials for the process using CS3 show a button for selecting "stack images" mine doesn't.
Am I doing something wrong?
Please help as I am going mad with it

I have a problem with photoshop. Everything I do gets pixelated.

When I paste or place an object from Illustrator CS6 I choose place as smart object and as soon as I pace it it gets pixelated. I have tried with and without the anti-aliased box checked. When the box is checked photoshop pixelates the image and when the box is not checked the image looks really strange and digital with the pixels showing. All curves that were smooth and nice in Illustrator looks jagged and strange.

When I try and draw a shape in photoshop it looks in the layer-list like it's a shape layer but the object is heavily pixeled.

I have tried opening a file created in Autocad (by using dwg to PDF) and opening it as a smart object in Photoshop. Everything is pixelated.

When starting a new file in PS I have a 300 pix per inch resolution, 16 bits RGB color, sRGB IEC61966-2.1 as my color profile and square pixels as my pixel aspect ratio.
Under general preferences I have the box for "Place or drag raster images as smart objects" (I have also tried without it). I have also tried with the box for "snap vector tools and transform to pixel grid" on and off.


Regardless of what i do photoshop still pixelates everything. I have no idea what to do. Could there be some sort of setting that I have overlooked?

Hi,

I am learning Photoshop in the hope of printing posters. I have questions regarding printing. Originally, when you create an image the resolution is set to 72 pixels/inch. I have learned I need to switch that to 300 pixel/inch.

1)Will I have to recreate all my images from scratch in 300 resolution?

2)Do I lose a lot of quality on the final product if i convert 72 -> 300.

3)My images are 11x17, when i hit 100% and view rulers, it shows my image at roughly a 3:1 ratio, why does it do this?

4)Can I view what a final printed image will look like with in Photoshop?

5)How do I preserve quality when switching to 300 resolution?

6)Say I use an image that is originally 600x600, will switching to 300 resolution make the new image horrible?

I may have more questions with as these get answered,
Thank you,
Geokatz

When I am processing RAW files taken by my camera, in the histogram should I try and get the three R G B graphs to overlap as much as possible so that the graph turns white with only the smallest amount of R G B showing?

Hello! Very much so a noob question . ive done my research and im just here for a very definite tutorial . im learning how to resize images from Big to small. Only problem is i cant seem to keep the high quality resolution . Ive included both images .. the "moonshine" collage is what id like to minimize. The "Whiskey" image is able to be downsized with no resolution loss when i downsize why? ID also like to keep them PNG or transparent in the background .

the moonshine collage image is one i made in photoshop cs6.

id like to make them W:280 pixels H:110 pixels/100 pixels



Theres a screen shot of the photo in place . The GREEN image is the image in low resolution , which i cannot figure why . the other RED image is how id like all my images to appear . There both pretty big original images as well ..

Hi all!
We're using photoshop to prepare assets for a game engine, and i'm trying to find a good workflow, which i can then teach to my artist.
At this point, i have an image with five layers. 12345

Layers 2-5 each have a layer mask on them.

Now what i want to do is, copy the layer mask of layer 2, and paste it into the Red colour channel of layer 1
then mask of layer 3 into the green channel of layer 1
layer 4 into the blue channel
and layer 5 into the alpha channel

So the result is that the channels of that layer will each look identical to the layer masks, and thus layer 1 will look like a wierd (but programatically meaningful) mishmash of colours.

I'm having some problems though.




Apologies for the massive image.
This is the green channel that i've gained from the above procedure. The big gradiented circle in the middle is what i made, but for some reason i have this white stripe down the left side too. I have no idea what that is or why it's there. It appears on both he green and blue channels when i paste in a mask. But if you look at the channel image in the right hand panel, it doesn't seem to have a stripe down it.

the stripe is definitely there, it's affecting the main image, and its annoying me.

any thoughts what might be causing that?

I've noticed that I get a good flow painting over a textured canvas (blank canvases are not for me) when doing so I work with a brush with the opacity set to about 45 and two layers, the bg textures and the actual image.
When I feel I'm done with my sketch I want to exclude the bg layer but still use the texture seen through the actual image i.e. I want to select all pixels in the top layer, merge this with the bg texture and then cut it out.

I've tried a couple of techniques (incl. ctrl + click on the layer icon) but not found any technique that selects _all pixels_ in a layer without me having to manually add some here and there.
Anyone have a clue how to?

Many thanks in advance.

Hi everyone, I introduced myself in a former thread. Name is Katie. I'm not new to Photoshop but am new to the more murky world of saving formats for various uses, printing, etc. I am in grad school, we're between semesters, and of all things they haven't really talked about saving! This week I was freelancing and saving to .JPG and .PNG, multiple images.

Problem:
I edited 150 images of product for a retail website on photoshopCS6. Company requires three sizes: two in .jpg, one in .png. Each image was in its own layer, in a group folder; a drop shadow effect was applied to the whole folder. For ea size requirement, I changed the canvas, resized all images at once to fit within it and ran the script.

I was able to run the Script on PS to batch save the .jpgs, and they RETAINED their canvas pixel dimensions in each image (700x525; 170x170). When I ran the same script to PNG-24, it worked but it DID NOT retain the canvas size and they were all wildly different.

I did some research, and found that people had to install script fixes to do this. I installed Dr. Russell's script for Image Processor Pro that should work in PS and Bridge. I tried it, still didn't work to retain size of PNGs. Am I simply using it wrong? Is that the only way to batch save certain file formats?

Because the images were due this morning, I individually saved every png ("save as" not "web/Devices") to ensure they were all 300x350.

I need to know there's a better way to do this for all other file formats, so I don't have to painstakingly save each image.
