Hi, nothing to do with GCU, but I thought someone on here might be able to help.
 
Ive been asked to email some work to someone at 300 dpi.  I always assumed this was the resolution.  I work in photoshop and when I check the image size the resolution reads at 300 dpi, only I have been told by the recipient that it is only 72dpi.  I am now totally confused.
 
Hope that makes sense.

I notice that going from program to program with a particular art project that the resolution dpi can change.  I have photoshop elements and that doesn't usually change anything.  But if I take an image say from photoshop elements at 300 dpi, into MGI Photosuite for some cropping or some effects, then back into Photoshop...the dpi began at 300 but is now back to 72.  I am wondering if the person on the other end is opening the image up in a program that puts the res dpi back at 72?  If that is the case will zipping the image lock its properties?  Anyway, as a final final, when I complete a project, I always finish it off in photoshop to make sure the size and res is where I want it to be, before I post it.

Hi Laura,
Are you exporting the file to a different format before emailing it, like from a psd file to a jpg?   If so, you want to make sure you're doing so at the highest settings possible.  Also, be sure to use Save-As instead of Save for Web.  Save for Web brings the resolution down to 72dpi.

"Zipping" means packaging a set of files into a single file or archive that is called a zip file. Usually, the files in a zip file are compressed so that they take up less space in storage or take less time to send to someone.
 
I am on a Mac and the system includes software to do that. I think PCs use WinZip software. But, that may not be your problem.
 
I'll bet Shaun is correct, in that you may be altering the dpi when you export the file.

Just to expand on the subject:
 
The Mac way to "zip" or compress files to send is "Stuffit" (at least that's what I use).
 
A jpg (jpeg) is often changed from a higher DPI to 72 DPI to send through email...  what actually does happen is a 5x7 image at 300 DPI is being received at almost 21"x30" at 72 DPI because 72 DPI is "SCREEN" resolution.  Still the same image.  But if the RECEIVER just changes the image back to 5x7 but keeps the 72 DPI they end up with a MUCH smaller and lower resolution image. . . that is NOT print quality, though looks great on the screen.  Making sense??
 
Also when YOU change size but not DPI (or vice versa) in photoshop DON't "re-sample" the image.  Look at the boxes for size AND DPI when you change either.  
 
Lastly have you checked in to using FTP to send work to clients??  Then you can send big files without having to worry about changing resolution.
 
Hope I've helped rather than confuse.

Dustin--
 
My Mac is 12 years old, but I have no problem sending to zips to my PC clients. . . whatever. . . Just thought it might be helpful for others who may also have older Macs.

Dustin-
 
I'm a New Englander: "If is ain't broke, don't fix it"      (Drive an even older Honda Civic   my third!   )  But you CAN only upgrade so far, especially when it comes to compatibility with PCs, but I keep pushing it!  I just upgraded my Acrobat 7.0 that "they said couldn't be done."  Now if I could just re-fit the old Honda to bio-fuel or electric   !!

Just another thought....how are you emailing them? If your using a program like Picassa then they can automatically resize what you are sending to 72dpi.
