Im stuck, stumped and a little bit thick. :lol:
For best large prints my DPI needs to be at 300? Right...?

Now...when I open any photo in elements 5.0 and I go into image size, it immediately says that it is 72DPI - so...is it my camera thats at fault? Or the Elements?

If its my camera, I have no idea what-so-ever how to change it.
If its elements, and I change it through "image size" to 300 dpi, instead of 72 dpi, and then send it via email. Apparently it still only coming out at 72dpi.....

confused?

I am....

:help::help::help:

:bang:
 
It's most likely the camera which is capturing the photos at 72dpi.

Are you sending the email from Elements ? It's probably converting your photo to web resolution before it sends. Trying converting to 300dpi, save the file, then use your regular email program to send it.

If its the camera that is capturing the images at 72dpi, any move further forward on this? As....:bonk: I have no idea how to change it, is it even on a camera's settings?
I have changed it to 300dpi on elements, saved it as a jpeg file, and then sent it via normal email on AOL....and it apparantly still shows 72DPI even tho I changed it! lol
 
You don't need to change the camera (and probably can't anyway).

If you open the changed/saved file in elements again - does it still show as 300 ?
 
If you search the forums for DPI you can see this comes up regularly.

My own take on it is to ignore it. Pixels per inch is all you need worry about. As long as your picture has enough pixels for that poster size print or whatever then end of story. Printed dots per inch settings are only relevant in a pro print shop. Photobox or whoever take no notice of your dpi setting in the picture file they just give you the best print they can with the pixels available.

but on elements it only shows me as DPI, not PPI

eg...said photo:
1643660410_8668bc27b3.jpg

^^ is 500 x 334 pixels via flickr...

On the Image data on Elements... it reads:
Width 3872 pixels
Height 2592 pixels

Document size
Width 32.78cm
Height 21.95cm
300DPI


Am I just worrying over this for nothing? :lol:
What would be a clearly "decent" sized print for those dimensions? What would you not go over?
eg..if I wanted to print it at A4, would it be a decent enough photo?
 
Pixels per inch you can work out for yourself from how many pixels you have and how big you want to view/print it.

The more pixels you have the sharper the detail can be. From the above A4 will be fine. As you can't sit with your face close to a 30 inch x 20 inch poster it would look just as good at that size too.

Its helped a lot...I will not stop stressing and just print it. hahaha
 
People oftne get confused about DPI. DPI is pretty much irrelevant in the jpeg or raw file itself. DPI is information for a printer. If you set your printer to 300DPI a 300 pixel by 300 pixel image would be 1 inch squared pretty much.
 
Dpi is printers banter, if you look at your file, it will say 72dpi straight off the camera, then if you look at the physical size of the image it will be around A3+, yes.

Right, to a printer 300 dpi is the 'industry' norm for the resolution of an image regardless of the physical size be it A5 or A1. You can print images that are less than 300dpi, but then you risk pixelation.

When we have files at work that are 72 dpi camera images we always have to 'shrink' them down when placing them into documents like indesign, you will find that to get an A4 image you will have to reduce the percentage to 24% and place it at this size.

Basically there are various ways of playing with these options to get the same result.

Back to your images, if you go to image size menu and uncheck the resample option (Photoshop), this then only lets you edit the physical dimensions or the resolution ie......

File is 72 dpi size is 121.92 cm x 81.28cm, if you then type in 300dpi in the resolution box you will then notice that the physical dimensions will reduce down to 29.26cm x 19.51 cm this is the actual sixe at 300dpi.
