<div>Hello,</div>
<div>i have reconstructed an USB stick with the fdk reconstruction filter. Within the slices there are different levels of brightnes. And the contrast seems to be low.</div>
<div>What may be the reasons for a low contrast and the differences in brightness of the slices ?</div>
<div>Thanks for helping.</div>
<div> </div>
<div>Kind regards,</div>
<div>Robert</div>
