الجواب وباللہ التوفیق

There is a difference of opinion about digital pictures among some eminent Ulama as you have mentioned in your question. In their view there is room for the permissibility per need in present day circumstances and needs. But the point of view of almost all Darul Ifta and the majority of Ulama of the Sub Continent is the same that the picture, no matter it is by a digital camera, Shara’n it is under the ruling of picture, neither taking picture is permissible nor making video. As far as watching and listening to the video Bayanaat, it is not without Karaahiyat, hence one should listen to the audio Bayanaat.

واللہ اعلم بالصواب
