Hey there -

I have a press deadline looming and I've never done a high quality render (yikes!)......basically I just need to do a 300DPI render. I've tested this, and rendered a region today, to see how large the file was. When I exported it as a jpeg, it was only 33kB, yet in the render dialogue box it said 'Uncompressed image size 2.5MB'.

Question 1: Does the 33kB refer only to the size of the region rendered? and the 2.5MB would be the size if I'd rendered the entire image?

Question 2: Have I done this right and is there a way to save the uncompressed image size?

Question 3: Is it ok to set the render on 'Best', 300DPI - or advisable to use custom settings....

I've done loads of reading on the forum already, and figured a few things out, but the file size is what I'm worried about.....it should be a decent size file.......

Any help would be greatly appreciated - thank you team!

PS See below for render dialogue settings etc....

You need to save it to a different image format. 

.tiff or .bmp will be huge, and uncompressed.  If you want to compress it intelligently, use a program like photoshop.  Revit slashes too much in its jpg compression.  way too much.

you can do "uncompressed" .jpg as your export, but I'm not sure I really trust that compared to tiff.

OK great - so you rekon, when I export the file, export it as a TIFF rather than JPEG, and it should uncompress it more....that makes sense actually now that I think about what a JPEG is...

Good to find this kind of thing out before I set the render.....cos it's going to take a few days I think...

well, the Mb size of the image revit is telling you is pretty accurate, and bitmaps and tiffs have no real comrpession, so they'll match that number.  Just make sure you export a few different takes of your render before you close it. I exported several day-long renders as 100kb .jpgs before I learned that.
