fontsizesize;subfloats
Is there any way of controlling the size of the subcaptions in a subfloat?
I've used:
\begin{figure}
\centering
\subfloat[Subcaption 1]{\label{fig:Pic_a} \includegraphics[width = 2.9cm]{Picture1}} \quad
\subfloat[Subcaption 2]{\label{fig:Pic_b} \includegraphics[width = 2.9cm]{Picture2}}
\end{figure}
So I've like to make the Subcaption1 and Subcaption2 smaller in textsize.
Thank you!
In case you installed TeX Live from the packages of a Linux distro: Most distros split less-used LaTeX-packages into separate (Linux-distro)-packages. From the link in your question I assume that you are running Arch Linux. In this case you need to install the texlive-latexextra package which contains subfigure.sty. If you are using a different distro, the necessary package might be named differently (e.g. texlive-latex-extra in Debian/Ubuntu).
Also, as Peter notes, the subfigure package is depreciated.
Here are some suggestions to fix your current situation:
Note the subfloat notation:
\subfloat[<LoF>][<subcaption>]{<body>}
Since your <body> consisted only of a \label command, the <subcaption> (actually, the <LoF> entry) had to wrap around something that is "very thin", causing it to not typeset properly. See page 4 of the subfig documentation for an explanation of this.
Also, the \label should be included in the <body>.
If you put the entire \subfloat within a fixed-width environment, the caption will wrap according to that width. This can be achieved via a minipage environment, for example. In the following minimal example, I've defined two new commands:
\vertfig[<subcaption>]{<body>}% For vertical figure placement
\horizfig[<subcaption>]{<body>}% For horizontal figure placement
that you can use to replace the traditional \subfloat. \vertfig typesets its contents in a 5in-width minipage, while \horizfig does so in a 3in-width minipage. Both dropped the second optional argument of \subfloat[..][..]{...}, since it didn't seem to matter to you.
As you can see, no fixed-width \captionsetup is required, since the captions wrap to the box they're contained in.

It is still very fierce-looking, right?]

geometry was merely used to set the paper size to a3paper.

As given in table 3 of the
subfigmanual, use e.g.Alternatively,
scriptsizeorsmall. You can also set the font of the number and caption separately, withlabelfont=...and/ortextfont=....
