What kind of distribution do I have if the histogram bins are exponentially increasing and it looks about normal?

A picture is worth a thousand words

Here's the situation. I've got a distribution of data that is heavily skewed to the right, and when I change my binning to be exponentially increasing (I used powers of 2 arbitrarily), it looks normal-ish.

At first, I thought I had a lognormal distribution, but now I think I have that definition backwards (I would have to take the log of the values and then plot. That doesn't help me here).

Now I am thinking Poisson, but it's been too long since I've taken a statistics class to remember how to use that.

I appreciate any help. My next step is to dig up my old stats book to see if I can figure anything out.

On my way out, I thought of an exponential distribution, but I don't know how to use those. If it's this, still tell me. I don't know if this is actually Poisson or if one is a generality if the other.

I've decided it's lognormal (ish... close enough for my purposes). When I plotted the log of my data earlier, Excel decided I wanted a Pareto chart, so it looked like this. I didn't notice until now.

But I fixed it and now it looks like this.
