Is MWAC back with the lesson plans of ROCKIN WHAT YOU GOT?

I believe that it's nothing more than a new member replying to a post that they may or may not realize is over 7 months old.

How could you not miss those good old fashioned contensious Posts os 7+months ago????? :-D :-D :-D

I know I use to be like a kid in a candy store waiting on the next lesson to come out. :)

Sporty, I have never kept up with MWAC. But I think she is either gone or MIA. I will say the lessons must have been a great deal of work. In her absence, maybe you could pick up the torch and start running with it. Nothing will teach you more about anything than doing the research it takes to teach something. If she came back, I'm sure the lessons would be popular. In the meantime, maybe you should try to fill her shoes.

That's a great idea.

MWAC has been gone a long time. She left after some particularly unpleasant comments. I would love to see someone pick up the torch.

Ok I will give it a try and see what happens. I will post tomorrow after I take my shots and show what i am talking about in lesson.

EXPOSURE TRIANGLE

It was suggested that I take over this activity. So I will give it a try and see how it goes.

Let see if we can get Exposure down pat for us Amateur Photographers. I first want to bring up the Exposure Triangle . 1.) Aperture: 2.) Shutter Speed: 3.) ISO The Exposure Triangle, consist of these three items used in Manual shooting Mode indicated my big M on the screen selected with our mode dial.

1.) Aperture- The Aperture is a hole located on the inside of the lens consisting of 6 overlapping metal blades designed to open and close depending on what aperture (F-Stop) f4.5, f5.0, f5.6, f6.3, f7.1, f8.0, f9.0, f10, f11, f13, f14, f16, f18, f20, f22, f25, (my camera) you have set in your camera. The aperture controls the amount of light that passes through to hit the sensor.

2.) Shutter Speed- The function of the shutter is to admit light into the camera by control of the amount of time it takes the light to hit the sensor. Indicated as standard shutter speed times in/on your camera and in viewfinder as whole numbers shown as fractions of time: 1, 0.8, 0.6, 0.5, 0.4, 0.3, ¼, 1/5, 1/6, 1/8, 1/10, 1/13, etc…………on up to 1/4000 (on my camera) know as fractions of Seconds.

3.) ISO- ISO controls the sensitivity of light falls onto the sensor. An easy way as was explained to me, consider ISO as a worker Bee, If I have 100 ISO worker bees set in my camera and you have 200 ISO worker Bees in your camera, and all the other settings are the same, aperture, Shutter Speed, who will get the picture first? You will with 200 ISO worker Bees. So we now know ISO settings go from Auto, 100,200, 400, 800, 1600, 3200, 6400 (my camera).

Now an easy way that I understand this process of Exposure is when we set Our Aperture (F-stop f5.6) and have an ISO setting of 100 our shutter speed is controlled by our settings which at this time pointing my lens at my lamp it gave me a Shutter speed of 1/5. So by saying this when we change one aspect F-stop or ISO we also control the operation of the shutter speed. This is called the Exposure Triangle.

Metering the Exposure

On Canon Cameras we have a Exposure Compensation meter shown by a line with tick marks and numbers along with. One side being positive and the other being negative.

-3 . .2 . .1 . . 0 . . 1 . . 2 . . 3 on Canon, left side is under exposed and right side is over exposed.

3 . . 2 . . 1 . . 0 . . 1 . . 2 . . 3- on Nikon, left side is over exposed and right side is under exposed.

Underneath the meter line on Canon we have a Blinky mark that moves back and forth to indicate under, proper, or over exposed. On Nikons I think the whole line moves if I am not mistaken. As we turn our dial to move the meter blinky back and forth to select our exposure our shutter speed changes to the give us the proper setting.
Exercise 1 Three photos controlling DOF (depth of field); The APERTURE controls the DOF as we know the lower the number in F-Stop (f-4.0) the more shallow DOF and the bigger the F-Stop number (f-22) the deeper the DOF. With this Exercise use the smallest F-stop number, then F-11, and F-22. I recommend using a tripod, shooting outside, selection a lone object either fixed in place or setup but also give you self some background to show your DOF. Please post along with these tree photos you camera settings or Aperture, shutter speed, ISO and Lens. I will be posting a Blue Bird house I have in front yard. Tell us what you noticed when you were taking these photos. Also play with them see what happens when you go through all the F-Stops. Try to keep you meter 0(zeroed) unless the sunlight does not allow it. You might want to underexpose.

# 3 really sharp and crispy, well done!

Are you holding the shutter release pressed half way?
It seems that you are letting slightly go when recomposing.

I hope and pray for your well being.
I just discovered your lessons Rockin' What You Got, which I find very educational.
I also noticed that lessons #3 and #4 were removed.
Are you coming back?
Lots of people are concerned about you and what took place that made you stop.
You built quite a following of devoted students who love and respect your dedicated work. Please, return to us, we need people like you. You are a pillar to this forum.
Our prayers are with you! God Bless you!

Pass it along to others :)
