File Formats

[Jameses]

I want to upload images to an art site, thing is they dont support .bmp (which most of my renders are). What would be the next best? and is .jpg ok for high quality images for printing? I have noticed some weird smears that happen over some areas of gradients they change very little over a significant distance with .jpg

png is lossless and web standard.

For printing, tiff and tga are common.

I use png for mostly everything.  

I find that bmp format is not good for anything except importing into programs that don't accept png!  The file sizes are just too big when converting to png saves so much space and is lossless compression.

What Sockratease said and: bmps are horrible: Not compressed at all and thus huge.

Just for web-uploads, jpeg with fairly high settings works great too. You can even save lossless jpeg (quality=100%), however, that then is less efficient than png. So if you want perfect quality without any informational loss, use png, but if you can live with barely noticable visual quality loss, take jpg at ~90-80% quality. jpeg's image size shrinks rapidly and those settings work fine enough.

Since you posted this under the UF sub-board under Windows Software, I assume that you are rendering with UF.  I am curious as to why you exported the images from UF in the .BMP format??  Especially with all of the other file formats which are available:

• .PNG
• .TGA
• .TIF
• .JPG
• .PSD
