histograms

Now that Milli has her own room (wow our bed is spacious now), I’ve trigger a childhood dream:  to have a tent in my room.  It’s set up, it’s roomy, and Milli loves it!  In fact, we typically find her napping inside her tent instead of the bed.

I’ve been talking histograms this week, so I decided to see how exposure changed the histogram.  I took three pictures, changing the exposure to make it lighter and darker, then viewed how the histogram shifted.  This lesson idea came from Darren Rowse.

Two Year Old Teenager

Milli turns two in April; but sometimes, she seems like a teenager.  She has mood swings, wears high heels, talks in a cellphone (which is ironic considering we haven’t had regular cell phone use while traveling), and now wears headphones.  There’s not music playing; I think it’s just a fashion statement.  Did I mention she’s carrying around a bag of cereal?

This week I’m focusing on histograms.  Yesterday, I gave a brief and basic introduction.  Today, I’m posting a picture of Milli that I took in Auto Mode.  This my biggest beef with Auto mode.  First, the camera always wants to use flash (unless you can remember to turn it off each time).  So it washes out Milli’s face, making it almost overexposed.  At the same time, the background is underexposed.  I’ve been wanting a richer, centralized histogram, and I think I get those more from my creative modes.

Introduction to Histograms

Now that I’m home and have my own computer, I’m finding more time to research some of my photography questions.  (Yes, my husband and I have been sharing one computer for 8 months, and he works online.)  I’ve decided to start studying a topic-a-week.  This week, I’m looking at histograms.  I spent a few hours today taking pictures of our possessions to update our stuff list.

This is what I know.  Most histograms have a five stop range from the left side to the right side.  I know that higher levels closer to any side of the histogram means excess, excess light or excess darkness.  Your goal is to centralize the information.  Here’s an example of a decent histogram:

Here’s the histogram for my image:

The dark light from the books in the back makes the spike to the left of the histogram.  The white book really reflects light making a spike to the right of the histogram.  The picture is dull and lifeless, and this is clear because there’s no depth in the middle of my histogram.

Now that I know how to read the histogram, how do I change things to get what I want?
