D60 / Digital Rebel resolution

[Macrossyiu]

Hello guys,
:)
I would like to know the MAX resolution for D60 and Digital Rebel.

My D60 only has 180 pixels/inch in RAW mode but I receive 2 TIFF files which from my client have 200 pixels/inch and 300 pixels/inch.

180 resolustions not enought for offset printting... right?

Can I increase my D60 resolution?

Forget about 180 pixels per inch. That is a totally bogus number.

You have an image of roughly 6 Megapixels, which is roughly 3000x2000 pixels. The image file has no other dimensions on it, so inches have no meaning here.

In your image editor, you can set the print dimensions to be whatever you want, and 300 dots per inch is a good standard to shoot for. Note that prints must have dimensions.

So, you got confused between pixels per inch and dots per inch.

it's really quite simple ... depends on the size of the picture to be printed.

The DPI of the (original) photo to be printed is the number of pixels in one dimension (e.g. 3000x2000) divided by the size of the picture in inches (e.g. 12x8). In the example, you would get 250 dpi.

Without changing the information content, you can save the picture in a different resolution (and therefore size) in Photoshop. If you change the dpi to 500, the resulting size of the photo would be 6x4.

If you want both (large image and high dpi), you must increase the number of pixels in the picture by interpolating (e.g. in Photoshop).

Hope that helps...

I can't answer your question, but I have had my D Rebel since October and sio far it is an excellent camera. However I got a D30 recently as a backup camera to the Rebel and find myself using it more than the Rebel. Anyway I have a battery grip and kit lens with my Rebel and looking to trade it for a D60. If you are interested let me know. I will throw in some other goodies as well...Dean

To continue from what I stated, and then what Andy stated...

If you have an image of 3000 pixels on one side, and if you want to achieve a print resolution of 300 dots per inch, then it looks like ten inches on that long side would do it. That is the maximum size that would allow the high standard of 300 dpi.

Then, if you relax your standards a bit, you can print a much larger print size. Poster prints tend to be rather low dpi, like 100-150, so your image file can produce a poster if you want. Note that posters are intended to be viewed from a longer distance, and that is why the lower dpi count seems acceptable.
