Infrared photography is not a new technique: it's been around
for over 100 years. The first infrared photograph was taken by Professor Robert Williams Wood and was published in the Royal Photographic Society Journal in 1910. Infrared photography became popular in the psychedelic hype of the 1960's, for example Jimi Hendrix, Donovan or the Grateful Dead released albums with infrared photos on their covers.

[link] So what is this infrared thing about?
Light can be described as an electromagnetic wave. The energy of this wave depends on the wavelength of the light. The range between
ca. 400-750 nanometers is called
'visible light', as the human eye can record only this part of light. 750 nm is the deepest visible red, while 400 nm is the deepest visible violet. The
infrared spectrum ranges from 750 to 1 million nanometers, but in photography we only use the
'near infrared' (read: this is the nearest to visible light) spectrum, that
ranges from 750 to 1400 nanometers.
Even though the human eye does not see the infrared spectrum, it can be recorded and thereby made visible using different mediums - analog black and white or color film specifically made sensitive for this wavelength,
or by any commercially available digital sensor. The look of these images varies depending on the medium, wavelength and postproduction used, but they have a few things in common:
the "infrared look". This comes from the different behavior of this spectrum compared to visible light.
As green foliage reflects more infrared light than visible,
foliage "glows" in infrared.
The infrared wavelength is
not susceptible to haze, therefore landscapes are outstandingly
clear, and
skies are much darker than you are used to with your own eyes.

However, fog or dust has the same effect on the picture as if it had been shot in visible light.
The human skin gets a
unique, alabaster-like look where all the small skin defects disappear (however, superficial veins become more visible).

What technical problems will one face if decides to do infrared photography, compared to visible light? (hotspot, focus shift, etc.) What are the most effective ways to solve/work around them?

I've searched so much and all that I find its from converted cameras and so on
