Listed over the coming pages are the different types of aircraft used by the Luftwaffe for Photographic Reconnaissance. I may have missed some types or variants out, if you feel I should have included a particularly one, please let me know and I will add it in my next update.  I will list them in manufacturer order.

Arado Ar 196 was a shipboard reconnaissance aircraft put in to production in 1936. The next year it was selected as the winner of a design contest and became the standard aircraft of the Kriegsmarine (German Navy). With the loss of the German surface fleet, the Ar 196s were added to coastal squadrons, and used to fly reconnaissance missions and hunt for submarines. They continued in service well  into late 1944.
This type of aircraft was not fitted with internal cameras systems, if there was a requirement for reconnaissance photographs to be taken, a hand-held HK13 or HK 19 would be used.

The Arado Ar 234 Blitz (Lightning) was the world's first operational jet powered bomber. However, it was  used almost entirely in the reconnaissance role. At first the Ar 234A series was designed without landing gear, it took-off my means of a large trolley which it would jettison, then on landing, skids would extend beneath the fuselage and under each engine.
The Ar 234A made its first flight in June 1943 and had an estimated  maximum speed of 485 mph, with an operating altitude of 32,000 ft and a range of 1,240 miles. The main A-series production was cancelled, even after the production had been stopped, seven prototypes flow, with V7 becoming the first jet aircraft to fly a reconnaissance mission.
Work started on the Ar 234B series and the first prototype was flown in March 1944, the first production version, the Ar 234B-0 followed in June of that year. Twenty B-0s were produced, next, the B-1 was a limited production of the reconnaissance variant. The B-2 quickly followed, this could be configured to fly either reconnaissance or on bombing missions. The recce version could be equipped with two Rb 50/30 or Rb 75/30 cameras (mounted in the rear fuselage), the aircraft could also carry two extra fuels tanks under each engine if required. It was reported that  reconnaissance missions over England and Europe in late 1944 were being flown by Ar 234Bs.
The prototype C-series of this aircraft first flow in late 1944, with the Ar 234C-1 being the reconnaissance version. However, the main production plant was destroyed in 1945 before being captured by the advancing Russian forces. The total number of reconnaissance versions delivered to the Luftwaffe was 210 Ar 234Bs and 14 Ar 234Cs.
In April 1945 the Luftwaffe list only 24 reconnaissance versions left in service.

The Arado Ar 240 was a twin-engine aircraft designed to be a fast heavy fighter that could also be used in the reconnaissance, dive-bombing and attack roles. The first prototype Ar 240V1 took to the air in May 1940, followed by the second prototype V2 in July of that year. In 1943 Ar 240V3 was used for reconnaissance trials and undertook a number of flights over England. Prototype versions V5 & V6  were designed as true reconnaissance variants, being renamed Ar 240A-0 and Ar 240A-1. On March 25, 1942 Ar 240A-0 was transferred to Aufklärungsgruppe Oberbefehlshaberder Luftwaffe. Generally there were a number of issues with the design which hampered further development of the aircraft. So by the end of 1942 production had been halted. However, there are reports that one aircraft was still flying reconnaissance missions over England in 1944.
based on the Ar 240 the later Ar 440 had a 90cm longer fuselage with a completely new cockpit and was completed in summer 1942, only to be cancelled in 1943. Only few planes went into experimental service within Luftwaffe, undertaking reconnaissance missions over Russia and southern England.
