In my two column LaTeX document, which uses a custom document class, I want to decrease the spacing that occurs between a figure's caption and the following text. An example of what happens can be seen here:

in this PDF Preview.

My thanks for any pointers on how to decrease the lost space.

I'm sorry, but I can't seem to reproduce your problem: PDF image and source. Could you add a minimal working example (MWE)? (I imagined it has something to do with the section coming right after, but adding one did not make the spacing as drastic as seen in your image.) –  Sean Allred Jul 27 '13 at 13:11

I really, really would be cautious in using this solution, and would ask whoever gave you your class file if it's okay to do first. Most publishers get a little... upset when you make redefinitions like this. Again, an MWE would really help pin down the actual problem.

A dirty trick (and one probably not allowed by your publisher) is to redefine the captioning.

Note that this will most likely break other spacing throughout your article, so even if it is allowed, I would be careful about using it.

If you feel comfortable editing the document class (probably not a good idea, since your publisher will have their own 'more definitive copy'), you can just make the necessary edit; otherwise add the following to your preamble:

\makeatletter
\long\def\@caption#1[#2]#3{\par\addcontentsline{\csname ext@#1\endcsname}{#1}{%
   \protect\numberline{\csname the#1\endcsname}{\ignorespaces #2}}
   \begingroup \@parboxrestore \normalsize
     \@makecaption{\csname fnum@#1\endcsname}{\ignorespaces #3}{#1}\par
     \vspace{-2ex} %%% Change this to your liking
   \endgroup}
\makeatother

Making the change drastic (3cm) produced the following on my end:

so it definitely decreases the space there.

Another, equivalently hack-y solution would be to add each \vspace as appropriate after each figure. –  Sean Allred Jul 27 '13 at 13:27

Thanks Sean, a \vspace does the trick. Thanks for explaining how to do it both in preamble and every figure. Since it's only a two page document will go with the per-figure hack. –  Caroline Jul 27 '13 at 16:49
