What's The Impact Of "resolution"-values?

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.

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 ..

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?

Hello,

I am completely new to this forum so I apologize if this is posted in the wrong place. I am using Adobe Photoshop Elements 9 and have a question regarding file size/quality. So, here it goes.

I am currently working on publication that requires all downloaded photos to be uploaded to a website that has a max file size of 20 mb. When I download an image to use for a background (some sort of a pattern that is normally somewhere around 800 x 800 size) the image is about 180 kb which is perfect. Unfortunately, the image has a poor ppi resolution and prints extremely blurry so in photoshop under image size, I increase the resolution so that the file size & resolution is bigger. This takes a lot of guessing on my part.

For example, if I increased the image resolution to 100000000 ppi, the file size would end up way over 20 mb which does me no good. So what I am wondering is, is if there is a way to optimize the the resolution of the image, given the file size limitations, without all of the guess and check?

If this looks confusing, I apologize and will gladly explain more. Any help would be greatly appreciated.

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

I have about 700 RAW images I want to batch process through PS.
All I want to do is reduce their size from 5184 X 3456 to 900 X 600 @ a resolution of 150 and save as JPG files.

Since RAW files run through ACR first and there's no way to reduce images size I just run it and end up with full size jpg's.
I run the JPG's again through Bridge and select Tools|Photoshop|Image Processor and selected "Open first image to apply settings" but when I run this there is no pause to reduce the file size.
It just runs through all the images allowing me no option to "Apply Settings".

I realize I can record an action to do this and use Photoshop|Batch but I'd like to know why this isn't working.
Thanks guys.

Hello,
l would really appreciate some help since I am coming to a deadline for printing some material. My problem seems to me like it should be quite eas, I have come close to a sufficient solution on my own but still not quite good enough resolution to print 24"x18" signs. In any case my issue is that I have an old design file of mine for a 5"x3" sticker with a logo on it as seen. When I try to enlarge it to the 24"x18" size the edges are way too pixelated. I have tried different selection techniques as well as refining the edges but no luck to make a high res version as yet. It's a rather simple shape and frankly I don't even care if it is redrawn to match at high res. In any case here is a copy of the logo in its native size on a 24x18 photoshop canvas. There is an image and an attachment Photoshop file, I would greatly appreciate it if someone can download the photoshop file and repost it with their efforts.
Thanks,
Dino

Hi,
I'm wondering if this is possible:
The right side is what I'm trying to achieve.
It's a simple enough effect, but the problem is that I'm curious if it can be some sort of dynamic effect in that I can change the "A" text to "B" and still have the outline cut out of the "M" (Or whatever if I need to change the "M" text to "Q" or something).
Basically I need the "A" and "M" to be able to change while the stroke of whatever the "A" letter (or shape) is will always cut out whatever shape, text, or image is placed behind it.
Is this possible without having to manually cut it out of the back image every time?

The illusion can easily be created by having a white background and using a white stroke on the "A" (that creates the effect I'm wanting)..
However I need them to be transparent and easily editable so they can be saved as transparent images for multiple uses quickly and easily.
(I apologize if I didn't get this across very clearly)

Hey guys,

So I'm a rather new music producer and I make some wallpapers for my tracks using Photoshop and then put some effects in there using Adobe After Effects.
So I usually just use either a gradient or an image in there, but it's rather hard to find images without copyright that look good and fit the track title.
And gradients kinda look boring (just a few colors that overflow).

So I was wondering how people make these kind of backgrounds:


(quality kinda sucks because I had it on 480p by accident, but you get the point)







Or a bit different style like this:


Or this:



Thanks in advance!


EDIT: I know the "READ ME BEFORE POSTING" thread clearly said "rather use img tags instead of linking to external websites" but it kept saying that I exceeded my tags by 20. So yeah, changed it into this. If anyone wants me to upload it to Imgur or something instead I'll do that.

Hello,

I'm in a bit of a hurry with this one and looked all over for how to do it. I have a logo I need to print out very big, every part in A3. Every letter went fine because you can resize words w/o them getting bad resolution. I have made an eggshape from a real egg picture. "Just white with blueish borders". And I want to know if it is possible to take this egg and resize it without it having a really bad resolution. I need it to be A4 or A3.
Here it is and here is the PSD file: egg1.psd
If you could explain a way to do it or make it A4 or preferably if possible A3 size with good resolution I would be very thankful!

Thank you all in advance.
