He frequently travelled outside Benin City, taking school portraits and photographing gatherings at social clubs, sporting events, and government ceremonies.

[1] In 1942, he created the Ideal Photo Studio in Benin City, where he quickly developed a reputation as a young, hard-working professional and an honest businessman.

He experimented with a variety of techniques, and he began creating product advertisements, documenting construction projects, photographing parties, and covering business conferences for local companies like Guinness Brewery.

Alonge took portraits outdoors with a large format, glass plate camera and a locally made studio backdrop.

Using kerosene lanterns, he developed the glass plate negatives at night and contact printed the images on gaslight paper.

[4] One such photograph was that of a proud Oba Akenzua II displaying the royal regalia of his grandfather, Ovonramwen, that was returned by the British to Benin in 1938.

[2] Alonge's photography preserves an important historical record of Benin arts and culture during the periods of British colonial rule and the transition to Nigerian independence during the 1950s and 1960s.

[5] The National Museum of African Art exhibited Alonge's work beginning in September 2014, displaying some of his rarely seen photographs.

The exhibition, which coincided with the Nigerian celebration of 100 years as a united country, was curated by professor and photographer Flora S. Kaplan, who corresponded with Alonge and visited Benin in 1982.
