Urgent Assistance Needed Please

Hi guys,

We've setup some large renderings which we need printed for an exhibition. The printed sizes are 3000mmx2200mm and 4500mmx2200mm respectively. The printing guys told us we need 300dpi images in order to get a good quality print at that size.

We've since gotten the extremely helpful guys at 3D Off the Page to render the images for us, however the resulting .png file sizes are too big for us to even open and work with. Is there a good tool we can use to reduce the file sizes? We need to add the logo's and get them off to the printers ASAP, but we can't work with the images.

I hope you are not saying that you had a 53000 x 26000 file rendered.. 

The only sort of thing that comes close to this that I know of are gigapixel panoramas, and they use specialised software to generate those out of lots of smaller photographs. but that software is not for editing thought.. but you might be able to find advice in that area about how to deal with such large image files.

Just off the top of my head, if you open photoshop (without loading the image) and in your preferences make sure that you allocate the maximum amount of memory to the program, so it would stand a fighting chance of holding the file in memory! I believe you find that under the 'performance' tab.

Otherwise, maybe give Gimp a try. it might approach loading the file in a different way.

Hi Niels,

That's exactly what we had done. I have 300dpi renderings at 53858x26349 courtesey of the guys at 3D Off the Page. They're all well over 600MB in size, with the largest one so far at 870mb 

I eventually managed to open them in Photoshop CS, which we had to purchase in a hurry. Luckily the interface is fairly straight forward and we managed to get what we needed to do done. I'm just waiting on the last rendering to come through now, following which it can also go off to print 

Thanks for the assistance!
