Hi All,

I started another thread on this some time back but as there are things I still don't understand I am hoping some one here may know the answer.

On the Alamny site it states

 

Note for images from digital cameras - We strongly recommend that images are captured on a digital camera capable of producing files of 17MB and upwards (6 megapixels). Please then interpolate the images to a minimum of 48MB using professional upsizing software.

This is the link if anyone needs it

I have a Nikon D100 which is 6 megapixels.If I shoot in RAW I get a 10 MB file per image.

Alamy states that the image should be saved as a jpeg file

I open the image in Photoshop CS2 and save the image as a jpeg and I end up with a 2.5 MB file.

Even using Genuine fractals 4.1 ( if I had it ) it will only up size the image by 800% without loss of quality ( They say it does ) so that gives me a 20 MB file,way short of what they require.

 

So how would one shoot a 17 MB file on a 6 megapixel camera.Do some 6 megapixel cameras acheive this.

Do I need a new camera :-( 

 

Maybe there is a simple answer to all this - sorry for being thick.

Any help greatly appreciated.
