I am trying to place two figures of identical dimensions side-by-side and align then vertically. However, one of the figures has a long caption which spans several more lines than the other.
As a result, the two figures are aligned but the two graphics are not.
How can I align the graphics rather than the entire figure?
\begin{figure}[b]
\centering
\begin{minipage}{0.45\textwidth}
\centering
\includegraphics[width=0.9\textwidth]{figure1} %
\caption{Short caption}
\end{minipage}\hfill
\begin{minipage}{0.45\textwidth}
\centering
\includegraphics[width=0.9\textwidth]{figure2} %
\caption{Long caption}
\end{minipage}
\end{figure}
