Smooth shadow of figure in beamer

I want to add a shadow to some figures in my beamer presentation. So far I have found the fancybox package. However, its \shadowbox{} looks quite old-fashioned:

\documentclass{beamer}
\usepackage{fancybox}

\begin{document}
\begin{frame}
\begin{figure}
\end{figure}
\end{frame}
\end{document}


I am wondering if there is any possibility to create smoother shadows with beamer as they can be created in Powerpoint like this:

Package tcolorbox has option beamer for boxes with shadows for use in in cases as it is yours:

Image is in tcolorbox:

\documentclass{beamer}
\usepackage{graphicx}
\usepackage[many]{tcolorbox}

\begin{document}
\begin{frame}

\centering
\begin{tcolorbox}[beamer,
width=0.8\textheight,
arc=0pt,
boxsep=0pt,
left=0pt,right=0pt,top=0pt,bottom=0pt,
]
\includegraphics[width=\linewidth]{example-image}
\end{tcolorbox}

\end{frame}
\end{document}
