David Adams left Jessops as chairman in February 2012.
Adams said he had left Jessops after falling out with the chain's bank, HSBC. He later made an unsuccessful bid to persuade HSBC to accept a private equity takeover deal.
Jessops went into administration in January, closing its entire high-street store network.
In a statement, Park Cameras, which is based in Burgess Hill, said: ‘David is a highly regarded figure within the industry, seeing Jessops through a tough transitional period...
'He brings a wealth of business and financial experience to Park Cameras, having held a number of senior executive, and non-executive, roles, within a number of household names across the retail sector'.
Roscoe Atkins, who is set to replace his father Reg as managing director, from 1 March, said Adams has a ‘deep knowledge of the retail sector which will be of great value to Park as the business continues to move forward'.
Adams' retail experience includes previous roles at House of Fraser and, most recently, HMV where he was a non-executive director until the music and DVD retailer fell into administration.
His current positions include serving as a non-executive director at Halfords, since March 2011.
Adams said: ‘I am excited to be joining Park Cameras at this time.
‘The recent changes in the industry create opportunities for a business that is focused on providing great service for its customers. I look forward to working with Roscoe and the team at Park to realise those opportunities.'
Reg Atkins, who is retiring from Park Cameras after 43 years, wished the team every success for the future.
Last month, in an interview with Amateur Photographer, Adams questioned whether camera suppliers would be attracted to the idea of a Jessops-branded outlet inside an HMV store.
His comments followed speculation that this was one of the options being discussed after HMV's restructuring firm, Hilco, emerged as among around half a dozen parties to have expressed interest in the Jessops name.
Dragons' Den entrepreneur Peter Jones later emerged as one of the parties to have bought the Jessops brand.
As we reported earlier, the Jessops website is set to be re-launched.
Hilco took control of HMV by buying its debt.
