Title: Please, please help
Post by: RogueSnapper on August 29, 2008, 10:24:58 PM
Hi everyone. I'm writing and taking pics for a newspaper now. I have a Cannon s5Is. The pictures are coming out at 180 dpi. They told me they're not of any use, they have to be a minimum of 300 dpi and said I can change it on my camera. However, I don't see it anywhere on the camera menu or anywhere in the user guide.
How do I fix this? I have a deadline Monday and it's a holiday weekend, I don't think I can take it to the camera shop to ask until Tuesday.

Do you have a "Quality" button?

I wonder if this would be what you need to change?

 You should do a search online. Maybe you can come up with an answer. Or you could always call the camera shop.

You said you have a Canon. So, if you camera came with Digital Photo Professional, you can adjust the dpi by batching the photo. That's how I do it. Not sure it will work though, if the pics are coming out of the camera at 180 dpi.

Let us know how it turns out.

Good  luck,

I found this online...

You cannot set the dpi value on your camera. In fact I don't know about any camera that does that. Digital cameras work in pixels. What you do is set the picture size in menu using available values which are:

L (maximum resolution, large size, 3264x2448 pixels)
M1 (medium1, 2592x1944 pixels)
M2 (medium1, 2048x1536 pixels)
M3 (medium1, 1600x1200 pixels)
S (small, 640x480 pixels)
W (wide 3264x1832 - used with 16:9 aspect ratio)

and don't forget to keep the compression ratio at "S" meaning Superfine.

Thanks. I can't find it online, and accidentally tossed the English user manual and kept the Spanish one.

I can't find the picture size in the menu, I've been trying, and can't find anywhere online that tells.

DPI has nothing to do with your camera's resolution.  It has everything to do with your printer resolution.  You can change your DPI in any good photo editor.  I use Gimp and it can be done from there.  I'm sure Photoshop or PSP will do it too.
