Sorry if this sounds dumb. I want to make my first submission but how do I reduce a shot to 150k and keep the 5mp quality?

What software are you using?

Hi skitch !
Start with this tutorial


If that doesn't help, let me know, I'll try to help you out with it. That should help, it's pretty good.
Welcome to DPC, good luck with your first submission and have fun!

short answer: you can't

it's gotta be resized to 640X640 or less anyways then start messing with the jpeg compression ratio usually somewhere between 85 and 99 seems to do it.

First of all reduce the image size - to fit the site requirements.

Dimension: No dimension may be shorter than 160 pixels or longer than 640 pixels.

just open ur image editing program - ex - PhotoShop .
Go to image size (make sure contrain proportion is selected)- put the longest side to 640 - and the other length or width will be reduced accordingly.

Now go to (Photoshop) save for web - and you get a few options to save it as select the best one you want and just save it.

Also - anyways you really dont need to use save for web - anyhow when the image size is reduced to that level - the file size will be less - just put the JPEG compression to about 60% to 70% and you'll be fine.

What if I don't have photoshop?

Well, like Scott said, it does depend on the software you use. I find the steps in the tutorial pretty decent. When you resize to 640, instead of just 'messing' with compression, use 'save for web', optimize to file size, put in about 146k, and it will find the best quality for you. That tutorial is pretty good, even if you already have a workflow you go by, it might have something you haven't tried that can help. That was the case for me. Worth taking a minute and looking over.

I dont know Irfanview so i would like to make a comment just on "free".
It is not free (just for non commercial use), if you feel (like me) this is important, use real free software (source code is available for everyone for any use) like gimp. //gimp-win.sourceforge.net/

Another option is of course GIMP - www.gimp.org

For more "Photoshop-likeness", you could also try Gimpshop -- a hacked version of GIMP that has had its menu structure and shortcuts re-mapped (whenever possible) to match Photoshop. It is available for Mac OS X (43MB!), Windows (8MB) and there are instructions for building it under Linux. Note that GIMP does not support color management yet, so the notion of "converting profiles" and stuff won't apply.

You can also try photofiltre, it's also free for non-commercial use. you can get it here this one gives you an option of previewing the filesize before saving it, it also has an option of maintaining the embedded EXIF data in your picture...
