Good question Cody and instead for sending you on a websearch for photo editing tutorials, I’ll give a recent example. I’m not an expert either but I can share what I know.

Personally I think the software supplied by camera manufacturers are either too limited or resource hogs. There are several freeware available, some were listed a couple years ago in the "Photo Editing Software" thread, for editing photos and some even provide an album system to help you organize your photos in your computer or online. I’ll be using Goggle Picasa for this example.

First download and install Goggle Picasa. Then select a photo and go into the edit mode. In the first tab you are given many edit options of which I use a few in this example.

Image
Original photo - EXIF data shows this photo was taken with a Panasonic DMC-FZ18 at ISO: 100, for 1/160s with f/4.2 and zoomed at the 35mm equivent of 803mm. The histogram shows the photo is on the dark side.

Image
Crop your photo to get rid of distracting objects (like your caving buddy who was cutoff by the framing) and to get the composition you want.

Image
Adjust levels with the one-click “I’m Feeling Lucky” button. Now the histogram is spread throughout its range and towards the lighter side. If you want more control of the levels you can go to the Tuning tab.

Image
Sharpen lightly, don’t overdo it. It’s like using salt, use just enough but don’t go overboard.

Image
And just for fun I tried the Redeye option but undid it because it ruins the effect I wanted.

Try all the options, you can always undo them. Try going to the Effects tab for other creative options. I'll stress again, edit lightly, just a pinch of salt and a dash of pepper; an overly edited photo can have a negative effect on the viewer.

Finally save your work as a copy. Don’t replace the original photo because you may want to edit it differently in the future.

The final photo in this example was posted on OnlineCaver.com as “redeye reduction turned off.”

Edit lightly and click on!

How is Picasa for storing / sharing your photos online? I need a place to put some cave pics.

I have a photobucket account, and like it just fine, but it's nearly full with other stuff.

I think this video was uploaded August 21, 2008 when Picasa 3.0 was first introduced; it is now in version 3.6 with much more options.

You can also see About Picasa 3.6 & Picasa Web Albums or click Picasa's Help menu (F1).

One of the features I like is the album visibility:

Picasa Web Albums makes it easy to share your photos with the world -- or you can choose to keep your photos as private as you'd like. Use album visibility options to control the privacy of your albums. You can set your album visibility options during the upload process and change them at any time in Picasa and Picasa Web Albums.

Public

Set your album visibility to "Public" to make them viewable to anyone who knows the URL of your public gallery. Your public albums may also appear in public search. Learn more about public search.

Unlisted

Set your album to "Unlisted" to limit who can see your album. All unlisted albums have an authorization key in the web address; the key is a combination of letters and numbers which make the web address very difficult to guess. Anyone that has the exact web address will be able to see your unlisted album.

Sign-in required to view

Select the "Sign-in required to view" option to set the highest level of privacy for your album -- you specify who has permission to view it, and those viewers must sign in to their Google Account to verify their identity. Users without a Google Account will be prompted to create one. Anyone not included on the album's "Shared with" access list will be unable to view the album.

Great post, pub! :goodjob:

I've been using Picasa for basic photo editing and online sharing for a couple of years. It works great for me.
