Pentax K100D

Hey guys,

This is my very first post here
I am currently trying to put together a brochure for my business and I am having some (lots) trouble with the images. I have taken some awesome shots but my designer says that they are only suitable for web use not print. Therefore instead of being x dpi they need to be 300dpi.
Any ideas on what I do? Also I don't have photoshop, would I require this software to make this change??

Thanks!

Just asked a friend of mine also based in Adelaide who just finished putting something to print, his words were.

"yeah photoshop because you have to convert to cmyk too, since cameras take in rgb"

He's a web developer by trade though, so someone might have a bit more to share.

For under $80 (and a how-to book, perhaps), Elements will work for either requirement (DPI or CMYK).

Printing will need CMYK - but your designer should have the tools (probably Photoshop) to convert from the RGB in the camera image to that - I do it on a regular basis. Most graphic designers are using a flavour of Adobe CS with Photoshop, Illustrator and InDesign to prepare publications.

As for the 300dpi - that is the preference for printing. If your images are 72dpi (screen/web) then that is an issue, particularly if they will be large images in the brochure. BTW - my raw images are 240ppi from my K200d.

Did you manipulate them before passing them on? Do you have the original images from your camera? If you have the original images then your designer can alter them to the preferred resolution and size during production preparation.

Good luck.

If your designer doesn't understand that the dpi number recorded in the image is completely arbitrary number that he is welcome to change to 300 if that makes him happy but has no effect whatsoever on the actual resolution of the image, then you should find a more competent designer. That's kind of like hiring a photographer who tries stuffing 35mm film into the SD slot on his digital camera because he heard that film was better than digital. Yes, it's that misguided.

If you are giving him the image straight from your camera, then it is 2000 by 3000 dots. If he wants it to come out at 300 dots per inch (which is of course what dpi stands for), then as long as you print at a size less than 2000/300 by 3000/300 (6.66" x 10"), it will be at least 300 dpi, regardless of the fact that the camera puts the rather arbitrary number "72" in the dpi field of the EXIF.

I agree. You should always, more or less, deliver your picture with as few alterations and as close to your native format as possible (if you have a 14 bit rgb raw, deliver a 16bit rgb tiff). The designer should know how to convert to the format HE needs.

I've printed 16x20 inch prints that I slightly sharpened that came from my k100d Super and 77mm and had no issues whatsoever. You've got plenty of pixels too worth with. 6mp is fine for brochure uses.
