Just got back from a short camping trip and I just unloaded 140 photos.
I have 6 photos that I hope I did them correctly. Reviewing the exif files does not tell me what I did.

I believe I started with auto, to sun, cloudy, interior light, flash & a white set.

Incandescent light on auto WB, then set the WB for incandescent. Will do the rest of the exercise tomorrow night.

Egg On White (With flash in a darkroom....)This shot I took by mistake along with the others in the order of all the white balance settings. I had my EV set to 1.5, and flash brightness set to -0.3. I do believe the first set come out better though. maybe a bit brighter or my monitor is just dark. The second set, I tried with both EV and Brightness on 0... I think its necessary to use the EV and bright controls in darker situations.. or depending on the mood I suppose... I really can't tell to much of a difference and wondering if though its on the manual settings, my camera still has control itself and doesnt matter what I choose....I have read somewhere about that I just dont remember where at this time... Maybe its my eyes...:) I do know that I have to get used to hte focus part after changing settings, its a extra bugar to have to press the shutter half way and wait for the light to focus...:) Then again taking time to do so assures me a better lock in photo....And thats defanetly what I am after....

Nice Job Ingrid! Great study! Looking at your and Laura's studies, I agree both cameras do a pretty good job with auto white balance. It seems to me that you would probably only use a custom white balance under unusual circumstances or if you noticed something really wrong with the colors and wanted to reshoot.

Bill, this is interesting. I had suggested the colored subjects against a white background to illustrate how colors change with white balance setting. Your study also illustrates it beautifully. Nicely done! Look at how differently the sun, sky and reflections are colored. If you can recall, which of these seems most like your memory of the scene?

Shooting indoors with incandescent lights is the hardest white balance problem for me personally. I think part of it is that incandescent lights are different colored. Some are frosted, some not. Some are new, some old. Some are in lamps with colored shades. Sometimes there will be different types of lights involved, halogen for example. And you may have natural light from windows. I can usually only get it right only with custom white balance ... and in fact that's about the only time I will set a custom white balance.

If I didn't know you better, Tracy, I would think you're toying with me. LOL They all look the same, how come?

According to your camera's manual, "When the flash fires, the white balance setting for flash is used. Consequently, to achieve a particular effect, the flash mode should be set to Suppressed flash."

My hypothesis is that you didn't select Suppressed flash and therefore the flash white balance setting over rode your manually set white balance. Could that be it?

We've come a long way in just a month. I have summarized where we've been, what we've learned and made a few suggestions in a Word Document. If any DPC folks have been following this thread and want my recap, just PM me with an email address and I'll send you the recap document via email. The word doc explains the background and rationale for the following.

Toward an Exposure-Centric Workflow

To get consistently excellent exposure we need to abandon automatic settings of our digital cameras. As we abandon them, we need to consider all the decisions we need to make. We need to think about which decisions we are willing to let our camera make and which decisions we want to reserve for ourselves. And we need to think about what this means for how we work as photographers. What decisions do we make? In what order? In short, what is our picture taking workflow?

I would make the following suggestions for sub-professional photographers who want to get great exposure results.

Suggestion 1: Choose full auto when everything is changing quickly and continuously or when you are just taking snapshots. Rationale: You will be distracted by your surroundings and won’t have time to focus on setting your camera.

Suggestion 2: Choose full manual for situations where you can control the environment (set shots, studio shots, and the still life.) Rationale: You have a lot of time and great control over the environment. You can use some of this time to obtain fine control over all degrees of freedom and get great photos perfectly tuned to the situation.

Suggestion 3: In all other cases choose Aperture Priority if your greatest concern is depth of field, and Shutter Priority if your greatest concern is motion blur. Then in the following order, take these steps:
• Set your camera to auto white balance. Rationale: Most cameras do a pretty good job and you can fix white balance problems in post processing pretty easily. Shoot a couple of test shots. Preset a white balance if you have the time and if auto is giving you poor results.
• Set your camera’s ISO as low as possible consistent with overall light levels. Inch it up as necessary being conscious of the noise as ISO gets bigger. Shoot a couple of test shots and adjust as necessary. Rationale: Light levels don’t usually change much as you shoot. Once you set it right you can forget it.
• Set your metering mode based on your subject, the composition you intend, the lighting conditions, and the contrast between your subject and its background. Shoot a couple of test shots and adjust as necessary. Rationale: With a given subject & background, once you get this right, you can usually forget it unless you’re unhappy with the results.
• Set EV Comp if necessary. Your experience with your camera will help you know when it might be necessary. Shoot a couple of test shots and adjust as necessary. Watch the histogram if your camera will produce one. Consider buying some exposure insurance by bracketing, especially if you won’t be able to reshoot or if you’re shooting film (how quaint!) Rationale: Since light levels won’t be changing much as you shoot, you can usually forget EV Comp once you get it right.

Since all the above change infrequently, you should not have to return to any of these settings for the duration of the shoot. However if the decisions below become problematic you may need to go back and bump ISO or choose a different metering mode.
• Now depending on whether you are shooting Aperture Priority or Shutter Priority, you will be adjusting Aperture or Shutter Speed just before you fire the shutter. And that is all you have to worry about. This is quick, easy, and highly responsive. Consider motion blur and DOF artifacts of your decision.
• Finally, you can adjust focus if necessary.

I just wanted to take a few minutes to thank Chuck for an excellent mentorship so far. I'm still amazed by how much I've learned.
I know you call yourself a mentor-in-training, but I think you've officially graduated. :-)

I totally agree!! It has opened me up. Now I take several photo's changing all kinds of things just so I can see what has happened.

I'm with Laura and Bill, amazed how much I've learned from the assignments posted sofar. Chuck, thankyou so much for your time, encouragement and the wonderfully clear explanations.

We have ended the Exposure Mentor Group Part I and started Exposure Mentor Group Part II. You can find the Part II thread here.

Hi, just wanted to find this thread easier.

Thank you soheil, I have been wanting to go over and do all of the assignments with my new camera so I could get a better understanding of the settings..

I have kept it on auto mostly, man its always perfect..
Then there are times when I dont want to use flash or I like to change the settings for exposure while shooting lightning.


Would anyone want to start a new group and work through these assignments too?
