I think each submission must simply abide by the particular challenge's rules.

depends on your software, but there is usually an option/menu choice for "adjust size" or "resize"--try the help menu in your app and search on size

then, choose units of pixels (not inches) and set the largest size down to 720, and make sure the option to resize proportionally is checked. Save and Voila.

I think they also have a limit of 200k file size on the images, so you might have to adjust the level of jpeg encryption to get that down to size.

I just submitted my first ever challenge entry, though, so I may have done it WRONG WRONG WRONG and be humiliated with a DQ, so take my advice with that warning :-)

File Format: JPEG (.jpg)
File Size: 150 kb or less.
Dimension: No dimension may be shorter than 160 pixels or longer than 640 pixels

do i resize it as i save, or resize the image and then save it as a jpeg? any suggestions?

Most photo editing programs have a resize feature. That's where you will do your resizing. Click on any challenge from the home page and the rules will include the size restrictions.

Hi Mitchell!
Welcome to DPC :-)
Try out this Tutorial. It should answer your resizing questions, and maybe some you havn't thought of :-)
Also, make sure you take a read through the rules for the challenge (in your case, the Basic Editing Rules.) Make sure you havn't inadvertantly done something that is not allowed, or not done something that is!
Good Luck in the challenge! :-)

Do all your editing first, then resize, then save for web or save as .jpg.

Usually any sharpening is applied after resizing and just before saving as a JEPG.

what program are you using to do this--I am working with mac stuff, so I may not be able to guess exactly

I would suggest first that you make a copy file, so any goofs caused by following instructions from the likes of me will be recoverable.

I have in my "tools" or "edit" menu selections choices like adjust color, and "resize image" or "adjust image" The help menu in your app should direct you to the right place. I would first Save As a new file name like MyImage dpc.jpg, etc. Then resize it, hit save again if it looks right.

For both our sakes, let's hope someone more knowledgeable than I will join this thread.

ah, good. the more knowledgeable folks have arrived!

Yes, absolutely make a copy, and work from that! You should never, that is, NEVER work on your original files.
Especially for dpc entries, but even in general, it is a very sound practice to always work on copies.

thanks for all the advice, i hope it works, i guess i will find out soon.

monitors vary significantly, and failing a calibration with a tool, I am not sure what to tell you. I think the tutorial mentions saving as sRGB color scheme for DPC, which might make a difference--but I am guessing that this is just the difference between monitors/graphics cards, etc. In this situation, I might just trust my newer/better equipment--if the laptop is high quality and the desktop monitor is low end, trust the laptop view, and ignore the desktop view.

I have a dual monitor set up at work--two different model Dell 19inch guys, and I cannot get them to look the same....

My images look different on my work computer than my home computer, too.

moniters drift off with time. If possible, you should calibrate frequently. Laptop moniters, unless extremely good ones, most people will say are not great for working with images. CRT moniters are what most serious folks use.
