Can you interpolate using DPP?

Is there a way to interpolate an image using the DPP software, in order to get those ridiculous 40mb+ images for websites? Or is their a better way?
I have looked around, and what some people like to do is load their raw files to DPP (in order to use Dust Delete Data), convert them to a TIFF image. then open that TIFF image in photoshop to interpolate it. The thing is, I don't have photoshop. Yet.

On the batch process dialog check the "resize " box and enter whatever dimensions you wish.

ya, i tried that. and even with me putting the pixels to maximum (9999x6666), i can only get around 30MB for an image. How high should the dpi be? any other ways?

For the Web, a "standard" display size for a jpeg would be something like 1024x768 pixels (depending on how you crop it), in other words, no more than 1024 pixels at the longest dimension will ensure that someone can view it normally on a monitor. PPI doesn't matter.

Another consideration depends on your Web host, which is file quality/size. For this site, 1024 at the longest dimension with a file size of max 150kB means a medium compression/quality, but your hosting site may have different requirements.

So, check your hosting site for requirements and follow their instructions. Just realize that any image you view "normally" on the Web will have much smaller dimensions/less pixels than your original file.

I think the OP is trying to up-res the images to meet stock sight requirements.

Ah, got it --

Some people resample first right out of their Raw converter, but in the end you'll probably want to resample in Photoshop to get the most precision. Just bear in mind that a 40MB tiff is not a huge amount of megapixels, so experiment a bit with your files to get the right "formula".

Not sure what the actual requirements are,but you will end up with a better (and larger) image if you export as a 16 bit tif, rather than adding garbage by interpolating. You are looking at the actual uncompressed image size, rather than compressed on disc aren't you? Huge difference.

An uncompressed 9999x6666 pixel 8 bit image would be around 190 Mb.
After jpg compression it could come down as low as 30 Mb., but stock sites express their requirements in incompressed 8 bit size.

P.S.

Dpi is irrelevent. It has no effect on file size.

Requirements stated in MB is so 80's...
