I'm just curious, what size do you recommend for rendering  a poster quality image in Bryce?

I've been trying to render an image in Byrce at around 3000 pixels, but it's day two now and I'm only on about 1% done.

Can one render a smaller sized image and still get a decent poster size print from it in Bryce?

Oh, I'm using Byrce 5.5. too incase that makes a difference or matters.

I Prefere the size of 1500 x 1005 with quality render  Super (Fine Art AA) Again it depends of what you will use your image for ^¿^ ( I can have rendering time 2 - 3 days as well depending on how much I put in the scene)

If you have a dual or quad core machine it DO matter that you are using 5.5 - Bryce 6.1 is able to use all the core's your machine has to offer :-)

When you say "poster size", a 3000X3000 pixel image would result in a 10 inch X 10 inch print house product printed at 300 dpi resolution or 20 inch X 20 inch if printed at 150 dpi.  (someone correct me if that is wrong)

Now what I can never get a grip on is: a printer will tell you you would need 6000 x 4800 to get a decent 16 X 20 inch print but my Nikon camera manual says my camera set at 3872 X 2592 pix will produce sufficient image resolution for 16 X 20 inch prints.  My guess is 150 dpi is good enough except for the most discerning user.

skiwillgee - i've got a company to ptiny a poster for me in A1 - resolution was 3307 *2339 in 150 dpi (they even say 100 is suitable) - the reaseon it produces a very very nice result is that you will look at a size A1 or bigger at a distance, which means you won't see the pixelisation very much - and i must say that even close up it looks fantastic

Thats what I was wondering how do you change the dpi in Bryce? Sorry if thats a stupid question everyone, but even though I've had Bryce forever I don't really use it all that much, and never have for a background for a poster print like this.

Thanks,

D.

you don't change the dpi in bryce. you render "enough" pixels and change the dpi in another image editing program.

dpi only matters to the output device.

calyxa - thats not entirely true - when you render to disk you have the ability to change DPI - furthermore you can make change the number of pixels to larger values than in Document Setup

Oh ok so if I render to disk I can change the dpi, otherwise if I say open it in photoshop, change the dpi in there and then re-save it, it will do the same thing without affecting the image quality and sharpness.

Cool thanks for the help guys. I owe ya's one. ;)

right, it's been ages since I've done serious rendering in Bryce that I completely spaced on the 'render to disk' having a dpi setting.

but all it does is set that flag in the header of the resulting image file.

one caution about changing dpi in photoshop -- when you do it, make sure that you've unchecked the 'resample image' checkbox (otherwise, changing the dpi will also adjust the number of pixels to keep the 'image size in inches' the same).

It is not recommended to increase pixels via photoshop more than 200% the original.  Otherwise, you get a soft image not good for viewing. Photoshop will calculate the color of the additional pixels based on the surrounding pixels; this results in reduced jaggies but also no crisp lines.   Bryce defaults rendering at 72 ppi, but as Nazul said if you render to disk you will be given the option of dpi quaility and will show you the dimensions of the resulting image at that setting.

When Printing DPI is very important.  8000x8000 or 10000x10000 at 72 DPI is still not good for printing. 

I once got bad info from here about resolution and got chewed out by a Professional Printer. :)

Rule of Thumb.

72 DPI - Screen Presentation.

150 DPI - More than enough for Inkjet Printing.

300 DPI - For printing posters and such.

dpi is what you need to calculate the number of pixels you need.

but it's still just a number in the header of a file.

if you do not have enough pixels, then it doesn't matter what the 'dpi' in the header is.
