    Brush Size And Large Canvas

    I do have a desire to paint very large, I'm talking 400dpi (or higher if a print shop says it will improve output) @ 6' x 4' as a minimum size. Large murals that cover walls...

    If I upscale an AR canvas, how does the percent brush size relate to pixel width? Just curious...

    As it is I've already busted 2GB mem and Intel Core Duo 2.16GHz with AR, so I know my current hardware is nothing like powerful enough to tackle very large high quality murals.

    But understanding brush size (as a percent), related to canvas size is important for upscaling.

    I think my workflow might be:

    initial ideas at low resolution as it's a fast
    load up a high res canvas and trace from the low res

    If you throw the best hardware at AR, does it have a mem limit?

    Hi there,

    You can find some information on the practical limits of memory with ArtRage here especially relating to large works:

    The brush size percentage is not relative to the canvas, it's absolute, so with a really large painting, the brush at 100% size is going to start to look rather small.

    Hope that helps!

    Hi Dave,

    Yes interesting thread... The DPI factor is an interesting one as quite a few print shops that specialize in fine art recomment 300dpi + for really fine work.

    Yes I understand you point entirely regarding viewing distance from larger works of art. But it's also true that if you want digiart to come anything like close to the experience of going up closer to trad materials to see brush strokes and finer detail, a higher dpi is essential of course.

    Big topic, lot of different approaches. But thanks for the thread ref, the 32bit mem address space helps. Maybe to think in terms of a triptych, it's becoming very fashionable now and many specialist print shops that output to canvas/frame are doing it.

    Thanks.

    Hi Furtrap and others,

    There are software programs available (free I think) which will enable you to expand a small image with a small resolution. I know that digital art and photography printing companies offer the service of being able to enlarge any image.

    One of these programs is called Imager. There are limits but try this link for more info. Hope it works. I have not had the chance to try it yet.

    I thought that I would add that higher resolutions can give you finer brushes and thus finer details...which is something that I require...its not just a printing issue. This is not an issue that is exclusive to Artrage, other sketching and drawing programs have difficulty as well. I routinely work on images that are 200 to 500 mb + layers. My system is a dual quad core with 8 gigs of ram and I get save errors in more than one app. because they don't make full use of the memory. Perhaps in a future version file size won't be much of an issue, till then I will work in sections and continue to support your product.
