Pixel dimensions for WebCam NX

I was wondering if anyone knew the actual pixel dimensions, i.e. the height and width of each pixel for the WebCam NX were. Does anyone know?

Andy, I'm not disagreeing with you at all and I fully understand how it works. I'm just not articulating myself properly. I'm only talking about setting the scanner software for best results. When you scan, you set the dpi and the size of the scanned document being scanned. The size of the scanned document on the scanner is a physical size (inches). The combination of the scanned size (inches), the dpi setting and the scale factor controls the resulting pixel dimensions. The scale factor should always be 100% for best quality.
When you scan a document you can't control the physical size of the document. It is what it is. So you need to select the physical size of the document on the scanner bed (in inches). Then to get the correct pixel dimensions, you need to select the correct dpi for the scanner to use. See my example in Epson Scan software.
If you choose a different dpi in the scanner SW, then the resulting image will need to be scaled after the scan is complete to get the correct "target" pixel dimensions. If you scale after scanning, you are either creating or destroying pixels. Better to set the correct dpi before scanning.
Note that the scale factor in my example below is 100%. That means the correct pixel dimensions will be captured natively from the scan and not modified after the fact.
I agree once you have the image scanned, the dpi becomes irrelevent. But it does matter to the scanner software.

Pixel dimensions for still images

Hello all,
I have just ran into a problem that seems to be a sizing problem with Final Cut Express HD. I used to crop my still pics to 1366 px - 768 px (for landscape) and then import them to FCE and export as a quicktime movie. When I brought the quicktime movie into iDVD and created the DVD it seemed to play great on my 46" Samsung tv -- full screen.
I just recently bought a Samsung 60" and when I create the same type of movies, I am getting a huge black border around the whole image (not just top and bottom but sides too). I tried creating a new movie and made all my still images 1920px x 1080 px, and it still comes out the same way.
I can stretch my tv so that they go full screen, but I think there should be a way to create the movie without having to stretch it....just have the tv set for 16:9, and I feel that it should work.
Any help would be greatly appreciated...thanks.
Norm

When you create a DVD, no matter what the pixel dimensions of your original material, it become 720x480 Standard Definition. This is what a DVD is. If you are creating a DVD that has material that is 16x9, then it creates a DVD that is 720x480 but plays back anamorphic, stretching to create the 16x9 screen.
If you play one of your older DVDs that played correctly on your previous TV, does it play correctly or does it also exhibit the black bars?
If it plays correctly then something has changed in the way you are creating your project in FCE.and encoding and burning the DVD.
If the older DVDs also exhibit the same playback problem, then I believe there is a menu setting on your new TV that will tell it how to display Standard Definition material from your DVD player, and you need to adjust that. (There are also settings in the set-top DVD player that tells it what kind of signal to send based on the what kind of display it is hooked up to.)

What are the pixel dimensions for creating an Apple ibook book cover?

I'm trying to create a book cover for Apple ibooks, what are the pixel dimensions requirements?

Thanks again.
Apple seems to have made it more confusing than it should be.
As an aside, the Apple documentation contradicts itself.
Cover art (also known as a marketing image or jacket) should be at least 1400 pixels along the smaller axis and must be a JPEG or PNG file in RGB Color mode.
This clearly says the shorter side must be at least 1400 pixels. The next sentence says this:
For an average trade paperback, this could be 400 x 1400 minimum size, as the books are generally taller than they are wide.
That doesn't make sense, seeing that the shorter side is supposed to be at least 1400 pixels, meaning it should say "1400 x 4900" for the same aspect ratio.
...I did notice this too.
So, if as you say, that the Cover Art and Cover image terms are the same and the 2 million limit does not apply, then it is unclear to me why Apple sent this message to me about cover file being rejected
"Action Required: Your book could not be delivered to the iBookstore.
The following images are larger than two million pixels and must be resized:
Full ePub: Cover_xyz.jpg "
I'll probably need to have the cover file in epub and Cover Image for Asset in iTunes Producer be named differently (but be copies of the same file) so I can understand which one is the "problem" file.
And finally, why does Apple refer to Cover Art twice here and then end in last sentence with Cover Image if they are the same ( and if they are the same why not state "this cover image").
"Cover art (also known as a marketing image or jacket) should be at least 1400 pixels along the smaller axis and must be a JPEG or PNG file in RGB Color mode. For an average trade paperback, this could be 400 x 1400 minimum size, as the books are generally taller than they are wide. For best results, deliver the largest pixel dimensions possible. When possible, match cover art to the cover contained in the book file. The 2 million pixel maximum does not apply to the cover image".

Pixel dimensions for iPad wallpaper

I want to set a background wallpaper for my iPad that won't be cropped or otherwise distorted to fit the screen. In the past all that was required was to pad an image to the appropriate proportions in photoshop, but when I created an image to be precisely the pixel dimensions of the iPad3 screen, 2048x1536, attempts to set it as wallpaper still resulted in the the wallpaper settings blowing it up.
Is there any pixel size at which the bug-ridden iOS7 will not attempt to blow it up, ruining the image?
Or is there a set degree of enlargement it uses, like forcing everything to be double, that I can use to pad an image so the forced crop results in the final image being correct?
I'm really tired of the seeing my wrecked images every time I wake the iPad. And no, I have no interest whatsoever in Apple's screenshots.

Hey Donot Haveone!
Try adjusting the following setting to see if it resolves your issue:

Pixel dimensions for stills in FPCX?

For use in a FCPX HD project, at what ppi do you recommend scanning? Then do you recommend taking it into photoshop? At what pixel dimensions do you recommend saving it -- and in what format -- jpeg or tiff? Thank you!

What Is The Best Image Pixel Dimensions For iPad 2 Photographs?

I just purchased an iPad 2 64Gb. I want to add photographs to my iPad. I want the photographs to completely fill the screen but still be small enough to use the minimum amount of memory space. A smaller image size will also make them more responsive when navigating between images.
Does anyone know the image pixel dimensions that I should use to have the photographs completely fill the iPad screen? I am assuming a resolution of 72 pixels per inch is sufficient because the screen is essentially a video screen.
Thanks!
Bill

1024-by-768 is the size of the screen.

Pixel dimensions for stills.

I am doing a thing with stills, want highest quality in the end. Do I rez down the files, and to what siz?
Thanks

One of the habits I've seemed to a have developed over the years (paranoid?) is initially importing all of my digital assets (photos, movies, etc) onto an external hard drive connected to my desktop computer. THEN I import those assets into iPhoto. It then makes it easy to use those photos, movies, etc in other application and also to avoid this "glitch" in iPhoto and iMovie. Seems to me this a bug waiting to be fixed.

Pixel resolution for slide show photos

Hello all,
What is the best pixel dimensions for doing a slide show to be watched on a hd lcd tv? I just did some at 1366 x 768 that seemed to work pretty well, but maybe the files don't even have to be this big...
Also I have a few photos that really flicker in the slide show...is there a way to eliminate this flicker?
Thanks,
Norm

Hello Tom,
Thanks for the info. My tv that I will be playing the dvd on is 1366 x 768, so my question is what is your reason for making the images 1280x720? Won't this make my images smaller on my tv or do they get resized?
I will try the blur in Photoshop and see if that corrects the flicker problem.
I tried the Flicker filter but I'm not sure if it even got applied to the problem images. I selected the image in the time line and then went up to filter and selected flicker...does this automatically apply when these steps are performed?
Thanks again.

Scanned handwriting in Tiff - DPI/pixel dimensions requirements for Printing

Namaste'
I am preparing to have a book printed of my Teacher's sayings in His own handwriting from His diaries.
The sayings were in ballpoint pen and some 20 years old.
We scanned them by a Greyscale hand scanner in 300dpi.
I have since cleaned and cropped them, so the 300 dpi standard is no longer there.
Since they are old, done with ball pen and not very thick, it is not realistic to take them "out" of their context, so they are on white background.
When I look at the scans info, it says 400dpi (the handwriting and the white background) but when I look at what the pixel dimensions say, they are all under 1 mb, mostly in the 300's to 700's k.
I do not understand this.
I was told 240dpi smallest.
What is the relation of pixel dimension to dpi? And how do I know this is enough?
Can anyone help clear this up for me?
When I take them down to the local printer and run them on their machine,for testing, the images look fine.
I am using PSCS3.
Thank you.

When I scan linework art like signatures, handwriting, pen-and-ink drawings, etc., I set the scanner for 2400 PPI at print size, 1-bit/lineart/monochromatic/bw mode (your scanner software should call it one of these, the important bit is that it is NOT greyscale mode).
The reason for this is most imagesetters and platesetters output at either 2400 or 2540 DPI, so scanning at or close to the output resolution provides the crispest appearance. If you are outputting to a laser printer or other desktop device you could scan at its output resolution, 600 for example, but a 2400 PPi 1-bit file is not large at all so why not "future proof" your scans so if you get them professionally output later they are at maximum quality.
Using a 1-bit file eliminates any soft edges as you would have with a greyscale image, and 1-bits can easily be made to have a transparent background so placing them into a layout is a piece of cake.
My best advice to you is to detemine your output size, then re-scan at 2400 PPI at the correct size.
To your other question, pixel dimensions refers to the actual number of pixels in the image, and is the only true measurement of resolution for a digital image. Until you determine the print size PPI (pixels per inch) is irrelevant, and the PPI will change based on the output size: if you have an image that is 2000 pixels wide and you print it at 10 inches then your PPI is 200 (2000 / 10). If you output at 5 inches then the PPI is 400 (2000 / 5).
DPI (dots per inch) refers to the resolution of an output device. The two are commonly used to mean the same thing, but they are not synonyms -- digital images contain only pixels, never dots, and printers output with dots, never pixels.

Custom cropping using pixel dimension

The banner image module for my website requires images cropped to 940 x 400 pixels. When I use the Custom cropping function in PSE 12 (on a Mac OSX 10.9.2), it only shows a cm dimension. Can I do a custom crop using a pixel dimension?

You should just be able to type 940 px and 400 px in the width and height fields
Another way is to use the Rectangular Marquee Tool and use Aspect>Fixed Size then enter 940 px X 400 px

How do you find the pixel dimensions of a photo to embed in Illustrator CC?

We recently upgraded our software from CS3 to CC. I'm having trouble determining the pixel dimensions of the photo I want to embed in Illustrator. In our old work flow, we simply clicked on the object in Illustrator, and then opened a new document in Photoshop, and it would retain the dimensions at our document size in Illustrator. It was then a simple matter to paste the photo into the box, position and crop and save as a PSD file and then place in Illustrator. That does not work any more in Creative Cloud. The object downsizes to 72 DPI while retaining the resolution setting. We need to keep our Illustrator files to the minimum, so embedding larger than needed files is not possible.
I've researched a bit and I see others with similar problems, but I haven't seen a workaround or a way to determine the pixel size. Document info in Illustrator gives the 72 dpi pixel settings, even though the document is set to reproduce at 200 dpi.
This is something that used to be so simple I didn't think much of upgrading. Now my workflow is horrendously long. I have to rasterize the entire graphic and then crop what is the inset photo. If there is a simpler way, please tell me. All the literature is backwards, about placing an already sized PS image into Illustrator. I need the other way 'round.
Thanks in advance for any help.

I think I have a workaround: Make sure the clipboard settings are on 72 by cutting and pasting a 72 dpi file in PS, as it seems Illustrator images are seen that way, no matter what the output resolution is. Click on Photoshop and start a new document. It will retain the proportions of the Illustrator image in 72 dpi. Then open image size and make sure the resample box is checked. Change the resolution to the desired, in my case 200.. Then place and crop your photo, and save the PSD file. Open Illustrator and place the PSD file. This works for me.

Is there any way to batch change resolution, but not pixel dimensions?

I was changing the resolution of my digital photos from 180 to 300 ppi individually as I edited them, but sometimes I would forget. Since I need the higher resolution for printing, I decided to automate that step by using PSE's "Process Multiple Files" feature. I noted that the Resolution selection was grayed out until I checkmarked "Resize Images." Since I didn't want to change the number of pixels, I left those fields blank.
When I started the automated processing I noticed it was terribly slow, so I cancelled it and looked at the resulting files. They had more than doubled in file size because PSE was nearly doubling the Pixel Dimensions! I don't want to try a work-around by "resizing" to the current pixel dimensions, because the processing still takes about 45 seconds per file, and if I've cropped the photos, the pixel dimensions vary. Is there an automated way to change only the resolution in PSE . . . quickly?
Also, I really wanted to double the resolution from 180 ppi to 360 ppi, but PSE limits my choices to either 600 or 300 or less. I've read about Scripts, but I don't think PSE supports them. I have version 6.
Thanks for some help.

Thanks for your input, and you may be right, but I'm not sure. I'm still trying to figure this out. I know it's the same photo on my monitor, but I keep reading that print resolution (ppi) is different from pixel resolution (i.e. 2000x3000.) This is my situation-- I'm sending the photos to a publisher for printing in a book. The publisher did not specify a size in inches--in fact I think the photos will be different sizes when printed on the page. They told me to send the photos in at 1600x1200 pixels. I've heard that 300 ppi is the standard resolution for publishing, so to get decent quality printing of my photos I thought I should increase the resolution from 180 to 300. But thinking about the different sizes, it seems that the resolution (ppi) will change depending on the size the photo is actually printed. At 300 ppi, a 1600x1200 photo will be printed at size 5.333" X 4". If a photo is printed full bleed on the cover of the book that is 8" x 10.667", then it will be 150 ppi. So, I guess you are right that I don't need to worry about the ppi resolution for the book photos.
Now, let me figure about what I need to print my own 4x6 photos. My digital camera was set to 16x9 jpg, so my workflow is to make PNG copies to work with and after editing, save them in the 16x9 format before cropping at 1600x1200 pixels, then sharpening before doing Save As jpg in Book folder. I was thinking I needed to change the resolution to 300 ppi when saving in the 16x9 format so if I want to later make 4x6 prints, I'll have good quality prints. But you have made me think a little harder--what I do is choose the 4x6 crop tool which takes care of whatever ppi resolution is needed for that size print. Oh good, you have saved me extra work. Thanks!
(BTW, I choose the 16x9 format because I was planning to use the photos in a widescreen slideshow, but my husband wanted something he could hold in his hand--hence, the book . . . and a lot of cropping!)

Where is it possible to batch process the size of images?--I am able to change pixel dimensions in image processor but not image size in inches.

Hi- I need to batch process images for video project. I am able to change the pixel dimensions in the image processor but don't seem to have the option to change image size in inches. Please advise! Thanks

You don't need inches for video (or screen viewing in general). It all goes by pixel count. Inches is for print, nothing else.
But to answer the question, you can run actions in the Image Processor, and this is where you set size in inches. Just bring up Image Size, uncheck "resample image", and specify size. You'll notice resolution changes to reflect the fact that the existing image pixels are now redistributed over the new print size.
But again, screen doesn't care about size or resolution. It only counts pixels.

How do I change DPI in Photoshop CC without changing the pixel dimension of the file?

I used to be able to do this in Photoshop CS6 by simply clicking the check boxes in the "image size" dialog box:
scale styles
constrain proportions
resample image
(all boxes UNCHECKED)
Then input the dpi (usually converting a 300dpi print file to 72dpi for web). And the pixel dimension will stay the same.
In CC the only option I see is "scale styles" which does not apply to the pixel dimension of the file.
Please help. I would hate to have to do this function in CS6 all the time.
CS6:
CC:

Just uncheck the [ ] Resample checkbox, then change your Resolution.
Change the units from Percent to Pixels if you want to see pixel dimensions.
Once you've successfully run it through (after OK), note that it will remember your units settings the next time you use it.

Would a photo with 70MB in pixel dimensions but low resolution print clearly?

Hi there,
Here is a snapshot of the image size window:
Is it true that if pixel dimension is very large in size than the resolution number under document size doesn't matter ?
I really woudl appreciate your help in telling me if my photo will print clearely choosing the belwo document size.
Many thanks!

This is the easiest way for you to get an acurate idea of what your image will look like printed...
1) Create a new document the size it will be printed and set the resolution to 300dpi (pixels/inch). (Due to the size you are going for I suggest using RGB instead of CMYK)
2) Open the file you created and (using the 'Move' tool) drag it onto the newly created document.
3) Zoom in to 100% and what you see is what you get when printed.
The distance the print will be viewed from is important however, for example, if it's a billboard the viewer is pretty far so the quality is pretty forgiving and a resolution of 200dpi should work.
Feel free to hit me up and send me one of the pictures and I will give you an acurate judgement on how they will look printed at that size.
