[Tex/LaTex] Beamer Frankfurt/Smoothbars Remove Shadow/Shading

beamerheader-footershading

\setbeamertemplate{title page}[default][colsep=-0bp,rounded=false]
\setbeamertemplate{frametitle}[default][colsep=-4bp,rounded=false,shadow=false]
\setbeamertemplate{blocks}[rounded][shadow=false]

removes the shadows from the frametitle, title page, etc..

\setbeamertemplate{headline}[shadow=false]
\setbeamertemplate{subsection in head}[shadow=false]
\setbeamertemplate{section in head}[shadow=false]
\setbeamertemplate{beamercolorbox}[shadow=false]

Did not help. 🙁

I wan to get rid of the shadow/shading in the upper slide.

You need a redefinition of the beamer@barshade shading used by the smoothbars outer theme (original definition can be found in beamerouterthemesmoothbars.sty):

\documentclass[ ]{beamer}
\usetheme{Frankfurt}
\useoutertheme{smoothbars}

\makeatletter
\AtBeginDocument{
\pgfdeclareverticalshading{beamer@barshade}{\the\paperwidth}{%
         color(0ex)=(black);%
         color(0.5ex)=(section in head/foot.bg);%
         color(4ex)=(section in head/foot.bg)%
       }
}
\makeatother

\begin{document}

\begin{frame}
test
\end{frame}

\begin{frame}
\frametitle{Test title}
test
\end{frame}

\end{document}

The result:

To influence the colouring of the mini frames without changing the background colour of the header, you can use the beamer colour mini frames (by default, this just takes the colours from section in head/foot, which is why changing this colour also influences the mini frames):

\setbeamercolor{mini frame}{fg=white,bg=black}

However, this only solves half of your problem: while it gives correct colours for the mini frames itself, the section name colour is still wrong, as it is controlled by section name in head/foot:

headline with mini frames highlighted/shaded as desired, but section name still in grey

To fix this, you can patch the internal beamer commands to use the mini frame colour instead of the header colour for the section name:

\usepackage{etoolbox}
\patchcmd{\sectionentry}{\usebeamercolor[fg]{section in head/foot}}{\usebeamercolor[fg]{mini frame}}{}{}

Together, this gives the desired result:

headline with mini frames and section name highlighted/shaded as desired

\documentclass[compress]{beamer}
\useoutertheme[footline=authortitle]{miniframes}
\usebackgroundtemplate{\includegraphics[height=\paperheight]{baggrund.jpg}}
\setbeamercolor{structure}{fg=white}
\setbeamercolor{normal text}{fg=white!80!blue}

\setbeamercolor{mini frame}{fg=white,bg=black}
\usepackage{etoolbox}
\patchcmd{\sectionentry}{\usebeamercolor[fg]{section in head/foot}}{\usebeamercolor[fg]{mini frame}}{}{}

I think, your footline disappeared, because it was overwritten with \setbeamertemplate{footline}[page number]
