[BlindMath] Digitising technical literature with the help of the smartphone

[Niels Luithardt]

Hello Stephen,
I am blind, but my seeing assistant prepares documents for me using
Mathpix. However, I still have old photos of book pages, which I would
like to edit with Mathpix now, but some of them were obviously taken
in a too bad resolution. I could have the books photographed again
with Mathpix, but maybe there is also a possibility to edit the old
photos on the PC so that Mathpix or the InftyReader could deliver
results. Could you possibly use an image editing program like GIMP to
increase the resolution or improve the image quality in other ways.
Do you have any tips on how best to take photos with Mathpix?
With kind regards
Niels Luithardt

> Hello,
> I have a seemingly simple question:
> How can I take pictures with the camera of a smartphone such as an
> Android smartphone or an iPhone with the highest possible resolution?
> The following background:
> I would like to photograph pages from old maths and physics books in
> order to digitise them. Unfortunately, there are many books that do
> not yet exist in a digital version.
> Professional book scanners are unfortunately not available to me.
> Therefore I only have conventional scanners or the smartphone for
> digitising.
> In order to be able to use programs like the Infty Reader effectively,
> I need pictures with a resolution of at least 400 to 600 dpi.
> Is it possible to achieve such resolutions with a smartphone camera
> and if so, how? Do you eventually have some tips for me?
> I would be very happy about any tips and hints!
> Many thanks and best wishes
