Title: Downsizing Photos
Post by: Vic on July 01, 2014, 15:32
Hi everyone,

I've just discovered this site and hope someone will be able to help me! I've been looking through the posts and I have a feeling I'm going to be here a lot :)

I want to upload some images to BigStockPhoto but the requirement is 25Mb or less. One particular image I'm trying to reduce is 34.8M, 4272 x 2848 pixels and 72dpi. I'd like to keep the pixel size as they say 4000 pixels sells more, although they accept 800. How do I reduce the file size? And am I able to increase the dpi?

Sorry if these are really basic questions! While I'm not new to photography, I've never really needed to know much about file types and so on.

Thanks for any help,
Vic

Don't worry about the DPI. The image size is the only thing that matters. The 25MB is talking about the saved file. In fact just ignore the whole dialogue box about size. Save your photo at the highest JPEG size. Check the file size of the saved file not the open one. You are surely not over 25MB.

Ah, right, thank you! Yes, I was looking at the open file size! I was getting muddled up with another site which I needed to look at the uncompressed size for.

Thanks again.

yeah, all the sites want the largest size you can send them, then they sell it for pennies whether it's small or large.  so I downsize for most sites now - the only ones I send larger sizes to are those that pay a reasonable amount like pond and fotoarabia

Thanks for your reply. I've just been uploading and I did have to downsize one, which was a huge huge file!
