I was editing some raw files my brother took, when I open one it gives dimension size,document size,color 3 RGB 8bpc or 16bpc, an resolution. His resolution was 240ppi. All my files of any photo will show as 72x72. Yes I know that is screen resolution. When I open a file (mine) in ACR than I get the 240ppi, even if I open a jpg. Is there an option in PSE 12, to let me do that automatically without opening in ACR first unless it is a raw file? Or am I going to half to edit in ACR to be able to see the correct ppi of any photo. PSE 12 does not allow you to open an edit in 16 bit. If that is the case will a newer PSE allow me to edit in 16 bit with all editing functions available? Thanks for ant help you can give me will be greatly appreciated. Hal

In what way is this a practical problem for you, Hal?

The difficulty for me in explaining this is that it is much more simple than people imagine it to be.

A file with three times the DPI than your screen uses will simply take up three times as much room on the screen when displayed at 1:1.

If that sentence didn't answer your question, let me know. As I said, this is so simple that it is difficult to explain (it is difficult for people to "hear" the explanation).

Mike Hello: Yes your right about the ppi being 3 x the size as screen resolution will take up more real estate on screen. But since I have a 20'' monitor it does not adversely effect me. It is just my preference to be able to see the real ppi of any photo. I did some playing around an discovered that the only way I will be able to see the correct ppi an image dimensions is to open everything in ACR. So that is what I will be doing from now on. I also shoot in large raw an jpg. Since I have a Canon T4i 18 mp camera which is very nice compared to my 1st canon 300d 6.3 mp big difference.Your explanation was very clear to me, some times if your not acquainted with PP programs the explanation can be confusing. That is what I love about UHH, there are people here who give a genuine answer an are willing to help those who may or maynot have a simplistic question. If I had done some testing with ACR first I would have found out my answer sooner. I thank you for your quick reply. Hal

What do you mean by "see the real ppi of any photo?" Also, I am not sure what you are "seeing" in the one program and not in the other.

If you are working with Canon raw files, you might consider using DPP.

Ok let me see if I can clarify: if I open a photo jpg file, PSE will tell me that it is 72''x48''-5184x3456-8 bit-72ppi-that ppi is from the monitor. If I open same image in ACR do any changes, click open image it goes into the editor but at bottom of image it will give me a more likely image dimension eg(10x8) 5184x3456-8 bit-240ppi. This is what I meant to say. You only see the latter ppi if you go thru ACR
from within PSE 12 I have DPP but it won't work because it tells me I need a 1024x720 or higher screen area or High Color or Higher settings so it does not open. It worked in Win 8.1 but Win 10 it will not open. I did update the program before letting Win 10 install. I think I need to install the previous versions from disk to get them to work. Maybe I'm not sure, have to get ahold of canon before I do anything, but I never did like the program anyway. PSE 12 does all my raw files easily. Hope I explained more clearly. Hal

No matter what your image is 5184x3456. That's pixels. If you divide 5184 by 72ppi, then that image will print 72ppi and make an image 72 inches wide. So your print resolution won't be very high. If you want to print that same image with better print resolution, say 360dpi, then your image will print a very nice 14.4 inch wide picture. Many printers print their best at this resolution. So when you first see an image in PSE at 72ppi, that's the print resolution. When opened in ACR and then transferred back to PSE as a PSD or Tif then it will be 240ppi because ACR is set to transfer the image at that print resolution. But if you want to transfer it back to PSE at a better resolution for printing, then while the image is opened in ACR just look at the bottom center of the image and you'll see what looks like a blue hyperlink. Click on that and you can change the ppi settings for this and for future images transferred back to PSE. This will not change how it looks on your screen at all. The only way to change how it appears on the screen is to go into the image size settings in PSE and change the image pixel dimensions. The image pixel dimensions are what you see on your screen according to your screens resolution. If your screen resolution is 1920 x 1080 then you can do the math and you'll know that at a 1:1 ratio the image will not fit your screen.

PPI, imho, is completely irrelevant, it's just a number plugged into the file when it's created. You can change the number to anything (like 5,000,000) and the file will still be that same resolution it was to begin with.

If your display is 2,880x1,800 and your image is 2,464x1,632 at 72 ppi the image will display on your screen exactly the same as an image of 2,464x1,632 at 300 ppi. 72 or 300, it's just a number like an amplifier with a volume knob that goes to 11 isn't any louder than the same amplifier with a knob that only goes to 10.

When you print the software will scale the image to match the printers requirements - you just pick the physical dimension of the desired print and Photoshop (or whatever) works it out for you - and it wont care what the ppi number is either - it's completely irrelevant.

jeep_daddy: Thanks for that explanation, I did the math an your correct. Now my understanding of what I thought was an issue was just my not knowing. An thanks for the tip on how to change the 240 to 360 in ACR an for any further ones I do in ACR, at least for the ones I want to print. Now when I see 72ppi It won't even bother me anymore. I always had a suspicion that 72ppi an a 72x48'' photo would never work. Thanks again Hal

sloscheider: thanks for your explanation from what jeep_daddy has pointed out and yours also I need not worry about the 72ppi anymore. Thanks again Hal
