Hi,

I've been contacted for a photo usage.

They asked if I can supply the picture, so they can make
a printout of 100x75cm with 150 DPI...

The picture in question was taken with a 2.1 megapixel
camera. (1600 x 1200)

So can I forfill there demand?

This is the picture in question: (don't click if you don't want to)

Thx for the advise.

Daniel

nice shot Daniel.

Try bringing the original into PS and setting the image size to 100 x 75 with:

Image> Image Size> Document Size and then uncheck Constrain Proportions

Hi all

Hmmmm, seems like the mail from Islandsflug has been doing the rounds.

I got it yesterday.

some small math:
100*75cm should be about 40*30inch which will bring you with 150dpi to
6000x4500 pixel.
Therefore I do not think that you will be able to supply that shot in a satisfying quality.
@Clickhappy: do you think PS will do miracles and make that size out of a 2.1MP camera?

To be precise, a print of 100x75cm at 150 pixels per inch (not dots per inch, there's a difference) requires an input size of 5906x4429 pixels - or around a 26MP camera if the image goes straight from sensor to output without cropping!

And therein lies the problem with shooting digital I guess... From a 10D/D60 size image, you might be able to interpolate up to that sort of size, but I'm not sure I'd want to hang my reputation on it. From anything much lower resolution, I doubt its going to work. A scan of a slide made by the right professional lab, however, could comfortably get you into that arena.

Hi all

They want the images for their office walls in Reykjavik.

It's a design company that are requiring the images.

Yeah, I did. I guess you have exposed me for the fraud that I am.
