Photo File Size Question

i have been taking my photos on the default "L" (18MP and like 5000x3000 res) <--not exact numbers but similar...

each photo ranges from 3MB - 8MB on the computer, after editing and saving/overwriting them they are still the same but mostly a little more than the orig. due to 'post' work.

is there a way to still save as a .jpg but to keep them in the "KB" range?

**I am using Lightroom for my post work and organization, thanks.

if you want low quality then yes, but JPEG is bad enough

You'll have to resize them so make the pixel x pixel size smaller.

Resize their pixel dimensions and resolution. People say 72 res is good for on screen viewing, but nothing print related. I'm not too good with this kinda stuff, but in photoshop I save as a jpeg  baseline optimized with max quality. All of the shots on my flickr are like that. The res and size can vary but the file sizes are near the kb range. No particular rhyme or reason, and there's probably a better way but my results seem fine.

In lightroom, all you have to do is select an image and export it. It gives you a choice for different versions, like web, forum, full, print, cmyk, rgb.

 make a websize export option.  resize image to 700px long side, quality 75, if they are going on the web than colour space should be srgb (most people don't have a colour space aware browser)

Why would you want them so small? You should be shooting RAW.

to put them online or to email people?

I reduce my 150mb raw files to 200kb files daily.

RAW is the beginning not the export, but I agree, why would you dumb down your photos? Storage space is so inexpensive...

why put high res files online?  They aren't needed.

Go through export in lightroom, pick jpeg, and drop the quality to about 80. Resize them to 1000px ish and they should be fine, I never have a problem even with 4 gig panoramas.

bump

so my folder where alll of my photos that i take are dividied up into Events, People, Scenery, etc..

in each of those i have the original (IMG_0001.jpg) and the 'post' image (IMG_0001-2.jpg)

do you guys suggest i make a whole new folder titled "originals" to import my photos in every time i connect my camera? and then when i am exporting them, resize/reduce image size? i ask this because i took a really nice shot the other evening and it was a typical 6.4mb image (4631x3112) but after post it was saved and it's 11.0mb. i do NOT want everrry picture i edit to be saved at this size?

finally, since i take my images at 18MP L on my 7D ( i guess the highest quality, besides RAW) i should not change that correct? but instead, only resize  and save the image after post as an "e-mail" friendly file (i use Lightroom).

thanks for the help

I'm a little perturbed that you have spent all that money on a 7D and have no idea about the remainder of the workflow.

Nevertheless, I'd shoot in raw if I was you, and let LR do it's thing with the originals, I.e; put them in one folder with subfolders for the dates of each photo. Then just have seperate catalogs for events and scenery etc.
Don't worry about file size, just buy another hard drive, it's so cheap and no reason to sacrifice quality

Once you've done all the post in LR then just export them as discussed above.

He didn't, his family buys him everything. It took us forever to finally convince him to not delete the original shots.
