Increase Pixel Count

I would like to increase the size of my image so that a decent, large format print can be made. I know of two methods of achieving this:
1. When using Image | Image Size, and changing the document (linear) dimension, the pixel size increases proportionately. No fractal or other image size supporting plugin is installed.
2. I can copy the image to three or more different file names, and merge all using File | Scripts | Load files to Stack, and Layer | Flatten Image..
So, I'm left with the following questions:
a. Which method is preferred?
b. Are the required pixels of the merged image equal to the dimension x resolution?
c. Is there a standard reference governing this type of activity?

For larger prints, you can use a lower PPI count, eg: go from 300 to 175 with 'no resampling' selected to enlarge the image, but that would depend on how large you want to increase the image and what machine is being used for the output. Most large format printers do not require the additional PPI.

How can I increase the pixel count (tolerance) that will invoke sizing handles to make them easier to select and use?

When working with Word tables, re sizing a column's width requires placing the mouse exactly on the line, waiting for the mouse pointer to change to the sizing control, and then you click and drag. The problem is that the tolerance is so unforgiving
(a few pixels one way or the other) that is rather difficult to get and keep the mouse in exactly the right spot to invoke the sizing handle. Because the tolerance is so narrow, by the time you click to drag, the handle control often reverts to a regular
mouse pointer because you moved the mouse a pixel, and instead you find yourself highlighting cell content instead of dragging the column width. And you have to keep repeating this process over and over trial-and-error fashion until you finally get the
sizing handle to display long enough to actually invoke it when clicking. It is rather frustrating. My question is this: Is there a way to increase the tolerance to invoke a sizing handle? In other words, increase the pixel count slightly,
either side of the line, that will invoke the control for the sizing handle? Instead of a few pixels, to something much more realistic/functional, like maybe 5 to 7 pixels either side of the line. This is also a problem when dealing with columns
in Windows Explorer - you find yourself dragging a column instead of re-sizing it because by the time you click the mouse, the sizing control has reverted to a regular mouse pointer - this has long been a source of wasted time and frustration to me. I'm
hoping there might be a way to change this in the Windows registry. Thank you.

Cool article, but not relevant.
I did not import from iPhoto nor Aperture.
I have my photos as JPEG files in a folder on my hard drive.
Photos, the app, did not make any duplicates. Rather, it made a giant Resources folder, almost as big as my folder of Image files.
FInder Info confirms the size increase and lost capacity on my hard drive.
But I appreciate the link. That could certainly give someone the same impression.

If you change the image mode of this image from 8-bit RGB image to Grayscale mode while in PSCS – what will the new Pixel Count be?

If you change the image mode of this image from 8-bit RGB image to Grayscale

If you mean by Pixel count the number of pixels, this will not change. The image will have the same size thus the same number of pixels.

Auto-Save-Option with increasing filenames (counter, timestamp eg.)

Hello!
I want to pdf a job of 30.000 single printer pages, which are generated by a computer programme.
I'm able to choose the Autos-Save-Option by setting a dedicated folder at the printer settings. But there ist no option to install an increasing filename (counter, timestamp eg.). For that reason Acrobat overwrites the previous file each time (30.000x).
In some freeware-tools this funktion is implemented. Where or in which version can I find this funktion in Adobe Acrobat?
Thank you for your help.
Greetings from Germany!

Hi, HiddenMist,
Following the suggestion, I have removed all information I can remove. I have set all settings to "contacts only" that can be set to such. I cannot change my avatar because I cannot save changes (without adding my last name, which is currently blank). I have left everything blank that I can leave blank. I have been contacted three times after I have made these changes, as suggested.
In the Windows Desktop version of the Skype software, I can navigate to my profile settings: Skype -> Profile -> Edit your profile.
My work-around still works ... for me, at least, which is why I continue to recommend it.
Hi, Bartholomue, and welcome to the community,
Did you know that if you look up how to delete your name from the Skype directory, it says that you are effectively disabling your account? Your name will not show up in searches, and it will remain in the contact lists of those who have already added you, but those contacts will no longer be able to call you.
Yes, indeed, this is true.
Best regards,
Elaine

How do you resize the pixel count from 4000 to 1600 in iPhoto

How do you resize the pixel count from 4000 to 1600 in iphoto?

In the Export Dialogue (File -> Export) note the options at Size. This will allow you to specify a maximum length or breadth for the shot.

DNG files not showing thumbnails preview icon on mac, after reduce/resize pixel count. Mavericks 10.9.2, Photoshop CC, ACR 8.4.0.199. Any Solution?

This is driving me crazy. With today's huge file sizes it seem to me that for the majority of pictures a pixel count of 12-16 mega pixels y more than ok size for editing and make printings; for the professional jobs is a good idea to have the biggest file we can. Due to that i was trying to convert some NEF files to DNG, saving some space in the process, But the impossibility to preview the picture's thumbnails and the file size (it displays 0x0) immediately take me to 1984, (Windows 3.11). and those are bad memories.
I don't know if this is an apple's or adobe's error, but it needs to be solved.
Anyone with the same predicament?

Thanks for your insight JimHess. Someone else on another post pointed out how Photoshop changes the color profile and other things and then trying to make this file into a DNG again confuses Mavericks (and, presumably, other flavors of OS X). Admittedly, the process I described is unorthodox and not what may want to do. Thank you.
A.J.: First, I am offended by your suggestion to omit my comment. I was simply trying to provide help in finding a cause of a general problem people are having across the internet. That problem, as you pointed out, is that modifying a DNG in some way in photoshop results in the thumbnail no longer being visible. Your modification is the size. Mine was not. But it was a general modification in photoshop and an attempt to reconstitute the file as a DNG that seems to be common theme, whether this workflow makes sense or not. Additionally, I'm very new to digital photography and tried to be helpful. I would advise you (as an educator who knows the consequences of negative first-time experiences) to be more mindful that not everyone on here is as experienced as you and everyone can benefit from being clearer in their questions and their comments.
Second, as JimHess pointed out, in manipulating a DNG file in any of the programs in a way that alters the actual file (not changing some setting that is ultimately stored in a side-car file or does not actually alter the photo) is probably the root of the problem. Changing the file size by altering pixel count may first require one of your adobe products to physically alter the file information in a way that stops Mavericks from being able to recognize the contents as RAW information. Does this make sense?
Best regards,
Robert

File size vs pixel count - slowing down my library?

Hello all,
I've been scanning 35mm slides at a high resolution (so that I can enlarge, crop, etc) then loading into my Aperture library. The files are between 5-7 Mb each but are approx 8000x5500 pixels which I calculate to be 44 megapixels. I currently have about 750 of these files (plus a few thousand pics from my xsi) in my library and they seem to be really bogging down my 2006 macbook, especially if I try to round-trip to photoshop or print a light table to PDF. It just comes to a screeching halt. I know that for 99% of the pics this resolution is overkill, so I'm planning on exporting them all to fit them to a 5x7 print at 400dpi. I'll then remove the originals from my library and re-import the smaller files.
If I export the jpegs at a quality of 12, the file size doesn't change too much, even though the pixel count is now only 5.6 megapixels. So my questions are:
1. Are these large files really bogging down my machine, or is there something else going on?
2. Will reducing the pixel count have any effect on performance, even if the file size doesn't change much?
3. Will reducing the file size (ie, change the jpeg quality to 10) have any effect on performance?
BTW, all files are referenced masters, my library is on one usb drive, and the masters are on another usb drive. This is the best I've come up with, given the limited space on my internal drive. Could this be slowing me down?
Thanks a lot,
John

MacDLS,
I recently did a little house-cleaning on my startup drive (only 60Gb) and now have about 20Gb free, so I don't think that is the problem.
It's probably not a very fast drive in the first place...
I know that 5MB isn't very big, but for some reason it takes a lot longer to open these scanned files in photoshop (from aperture) than the 5MB files from my camera. Any idea why this is?
Have a look at the file size of one of those externally edited files for a clue - it won't be 5MB. When Aperture sends a file out for editing, it creates either a PSD or an uncompressed TIFF after applying any image adjustments that you've applied in Aperture, and sends that out. Depending on the settings in Aperture's preferences this will be in either 8-bit or 16-bit.
As a 16-bit uncompressed TIFF, a 44 megapixel image weighs in at a touch over 150MB...

Can LR filter or sort by pixel count or file size?

LR ought to sort or filter images by pixel count and by file size. I can't seem to figure it out. Consider adding this capability.

No, but no harm in asking for the Feature.

How do I prevent Adobe DNG Converter 7.4 from cutting image pixel count?

I converted 5D Mark III Raw files to DNG with Adobe DNG Converter 7.4. When I import the DNGs into LR I noticed that the total pixel count has been significantly reduced. The original Raw images are 22 megapixels (5760 x 3840), the DNG files are 10.5 megapixels (3960 x 2460). I tried it without lossy compression, and with Lossy compression (making sure preserve pixel count was selected). Either way the image's pixel count is reduced. How do I avoid loosing half the image? Am I missing something?

Simplistically,
The image is captured with the full sensor data and then is downsampled during in-camera processing to create a smaller version that retains the Raw bit-depth. That resultant file is saved on the camera's memory card. So while all the MP of the camera were used, the output file is smaller in MP.
There are probably much better technical explanations for how that happens. http://dougkerr.net/Pumpkin/articles/sRaw.pdf Pages 6 and 7,
Mind you, I suspect this is what happened. You need to verify with your second shooter. The pixel dimensions match exactly with mRaw.

Pixel counts for specific RGB values

Can Photoshop CS4 find pixel counts in an
image for specific RGB values? Where would
you input these RGB values and would you see the pixels highlighted and totaled?

Hi Zeno:
Thank you very much for your response!
Your directions work very well for a single image. I have an entire series of images and was wondering if I could just enter a specific set RGB values some where and see a total pixel count for each one of them.
When I go to foreground color and enter the RGB values there and then set the color range to zero and press OK, I get a Warning: No pixels were selected message.
Any additional advice that you have would be much appreciated.
Thanks, Bretzfrog

Photo scanning -- cropping using pixel count for dimensions?

Hello, I have both an older Photosmart 3310 and a new Officejet Pro 8610. When scanning using the 3310, I can control cropping of the previewed scan using pixel count (width and height). I can't seem to do that when scanning using the 8610. Dimensions are in inches and only. In fact, my editing options on the previewed scan on the 8610 seem quite limited relative to what I can do using the much older 3310. Am I missing something? I want to scan on my new 8610, but I also want some control over the scanned image like I had with the 3310.
Thanks.

Hello there! Welcome to the forums @JGH28 ,
Yes, you are in fact correct. The software definitely has changed over time and is much more limited with the software for your scanning options for the Officejet 8610 compared to your Photosmart 3310. Unfortunately there is not a way to change the options you have to broaden them again.
I would only suggest to ensure you have installed the Full Feature software for your Officejet 8610 to ensure you are seeing the full options available for your printer: HP Officejet Pro 8610 e-All-in-One Printer series Full Feature Software and Drivers

Total pixel count for specific shades

I am photographing fixed points along an artificial stream bed and want to document algae growth in it over time. There may be up to 7 different shades of green (types of algae) in a given photograph.
Can Photoshop CS4 separate these shades and give you a total pixel count of each shade?
I was told by techical support that if you select an area with a tool that the histogram can give you a pixel count (along with the RBG values) for that given area. Is there a way to click on a particular shade point and have PS computate the total pixel count of that shade in the entire photograph.
The magic wand tool does not appear to be a reliable tool for this purpose.

Hi Paulo:
Thanks for your response! When I go to Select/Color Range and set the bar to low fuzziness, I get an eye dropper. When I click the eye dropper on the photograph, nothing happens in the histogram to indicate a pixel count. I am missing a step?
Thanks, Bretzfrog

Images coming in at wrong pixel count

When I started making my website I put a background image in that was sized perfectly in Photoshop. I made the pixel count identical to the size of my website. Today I went to edit the background image in photoshop and remove a few lines from in. I saved the image (the pixel size, count, and ratio were never altered) and relinked the file into my website. The file is now coming in way too small. I tried bumping up the pixel count (drastically for good measure) and the image is still coming in way too small. Anybody have a solution?

If you open the assets panel and mouse over the entry for this image, you should get a tooltip describing the size of the image on disk, in the muse file, and the size it's being used at in Muse. A screenshot of that tooltip would be helpful.

How do I increase pixels?

How do I increase pixels in iPhoto?

you can not "increase" pixels in any way (PhotoShop will add pixels by interpolating new pixels between the existing ones but it does not increase photo quality) - you need to start with the pixels you need - everything you do after the initial photo is created will at best leave them alone and generally will reduce them and reduce quality

I need advice on how to increase pixels (to 1000+) on images currently in the 6-700 range

Hello,
I need some assistance. I am new to Adobe Photoshop. I need to increase the pixels to around 1000 from the current 6-700 the images currently have. The photoprinting company I use told me I could do it on Adobe. Any help would be appreciated. Rich Shay [email protected]

You may think you need a solution to change existing small images to make them larger, but keep in mind that what they may really be saying to you is that you need to prepare the images so that they end up with more than 600 to 700 pixels width to begin with, so that the images have enough detail that they'll look good and crisp in the prints. To advise you further on doing this, you'll need to describe a bit about where you get your images initially and how you process them into these small versions.
If you really DO need to upsample existing small images to try to give the visual impression they have more detail in them, just doing Image - Image Size isn't really going to help - they'll still look fuzzy. BUT... There are a couple of pretty cool (and reasonably expensive) plug-ins that do some fancy shenanigans to make images seem to have more detail than they really do... You might want to try out either the Perfect Resize 7 plug-in by OnOne Software, or the Blow Up 3 plug-in by Alien Skin software.
