Polaroid photo effect in tikz
Edit (2016/05/27): Improved version at the end -- cleaner box style, usage of xparse.
Something like this
Description: I defined a command \polaroid, taking five arguments, the first being optional, designed for the tcolorbox only.
- 1st arg:
tcolorboxsettings - 2nd arg: Rotation angle in degrees
- 3rd arg: Scaling of the image
- 4th arg: Image file name
- 5th arg: Caption
The shadow is blurred now, the detailed settings depend on the personal request and can not be done here, change the fuzzy shadow option values at will.
\documentclass[paper=a4,12pt]{article}%
\usepackage{tcolorbox}%
\usepackage{etoolbox}%
\tcbuselibrary{skins}%
\begin{document}%
\newcommand{\polaroid}[5][top=1cm,left=1cm,right=1cm,bottom=1cm,boxsep=0pt,colback=white,width=8cm,arc=0pt,auto outer arc,fuzzy shadow={2mm}{-2mm}{1mm}{0.3mm}{black}]{%
\tcbset{enhanced}
\rotatebox{#2}{%
\begin{tcolorbox}[#1]
\begin{center}%
\setlength{\fboxrule}{0.2pt}%
\setlength{\fboxsep}{0pt}%
\fbox{%
\includegraphics[scale=#3]{#4}}
#5%
\end{center}%
\end{tcolorbox}%
}%
}%
\polaroid{-10}{0.25}{face}{\Large \textsf{\textbf{Hello World!}}}%
\end{document}
Old version
\documentclass[paper=a4,12pt]{scrartcl}
\usepackage{tcolorbox}%
\usepackage{etoolbox}%
\begin{document}%
\rotatebox{10}{\begin{tcolorbox}[width=8cm]%[shadow={2mm}{-1mm}{0mm}{black!50!white}]
\begin{center}
\includegraphics[scale=0.5]{bild_erwin_schroedinger}
\Huge Hello World%
\end{center}
\end{tcolorbox}
}%
\end{document}
About the jaggy lines issue: Adding a tight \fbox around the image overprints the lines, but it is only a work around.
Admitted, Erwin Schrödinger is not as sexy as that actress ;-)
Update A better version, with tikz styles and special settings:
Another version of the \polaroid command, this time with xparse:
- 1st arg optional:
tcolorboxsettings - 2nd arg: file name
- 3rd arg optional : Scaling of the image
- 4th arg: caption
- 5th arg optional : rotation angle

Here is a flexible and customizable solution usable into a tikzpicture.
Description of keys:
atdefines the center of the picture,graphics optionsdefines the options used by\includegraphics,rotatedefines the global rotation of the polaroid,captiondefine the content of the caption,caption distancedefines the distance between the top of caption and the bottom of the picture,top margin,bottom margin,left margin,right margin,vmargin,hmarginandmarginare used to define the margins between the picture and the borders of the polaroid,caption optiondefines the options used by the caption node,frame optionsdefines the options used by the frame node (the whole polaroid).
Each key has a default value. The optional argument of \polaroid macro is used to change these value for a particular polaroid. You may use \polaroidset to change the default values for all subsequent polaroids in the current group.
