\caption full features, but no showing at list of figures?

Question

Using tocloft for my list of figures, I am looking for some method that enables me to select some specific entires (\caption) such as that one further down, which shouldn't goes to the list of figures, but in the content still be counted/numbered in the usual way.

\begin{figure}
\centering
\includegraphics[width=1.0\textwidth]{rhythmus.pdf}
\caption[Own grafic.]{Beispielrhythmus: Ta ta tatata, tata tataa ta taa.}
\label{rhythmus}
\end{figure}

I use the list of figure to show the sources of the figures, but I have many selfmade grafics, where I don't need to specify the source. Respectively I will specifiy them just with one sentence.

I have following settings in the preamble, which might play a role.

\usepackage{tocloft}

\usepackage{etoolbox}
\usepackage{lipsum}

 % This is for using numbering for the sections, chapters, etc. in the content, but not in the table of content.
\makeatletter
\let\oldnumberline\numberline
\patchcmd{\@caption}{\numberline}{\oldnumberline}{}{} %
\renewcommand*{\numberline}[1]{}
\makeatother

Then:

\chapter{List of Figures}
{\makeatletter
%\let\@cftmakeloftitle\relax
\@starttoc{lof}% Print List of Figures
%\listoffigures
\makeatother}
\begingroup\noindent \footnotesize{Abb. 1.1, 1.2 ... here some more.. are made by myself}\endgroup

Answer 1

Doing

\begin{figure}
\renewcommand{\addcontentsline}[3]{}
\centering
\includegraphics[width=1.0\textwidth]{rhythmus.pdf}
\caption[Own grafic.]{Beispielrhythmus: Ta ta tatata, tata tataa ta taa.}
\label{rhythmus}
\end{figure}

will neutralize the writing of anything in the .lof file. The effect of the \renewcommand will disappear at the end of the environment. Of course the optional argument to \caption serves no purpose, in this case.
