India has done very well with its space missions considering its meager budgets, but it is disappointing to me that they are just as 'cheap' when it comes to releasing photos or scientific data, as are all the other space agancies.
Earth as seen from the camera on the Vikram lander of the Chandrayaan 2 mission. It would appear to be the same or similar Bayer filtered, 2 MP indutrial camera that the has been used on NASA misions.

Photo from Vicram lander camera of the western far side of the Moon, so would be lit by sunlight but not Earthshine. No details of exposure settings or any post processing are available, but I suspect it had been adjusted to look brighter, as were the later photos available of the Israel photo of the far side.

In this 10 minute video by Scott Manley he examines the recently released images of the Moon from the Chandrayaan 2 orbiter and compares them to the LRO images. Very little difference, and when looking into the 'camera' specs it can be seen that both units go into the 'extended red' region, one to 750 nm and the other to 850 nm. They are panchromatic so no filters, which again means that they are likely capturing just the strong IR.
IMO, the photos are very poor resolution, and some images from Earth using high end amateur telescopes seem almost as good, surely better ones must be possible.

I suspect the problem is that taking real photos (the Chandrayaan devices use push broom sensors) would result in a great deal of motion smearing as the exposure times would need to be longish to capture enough photons under the Moons low illumination levels. There is a good reason why they do not send a Lunar orbiter with an Imax type video camera, even though units such as the ones by ARRI are cheap by aeorospace standards.
