The reaction amplitude is constructed by considering the <math><mi>t</mi></math>-channel <math><mi>\u03c0</mi></math> and <math><mi>\u03b7</mi></math> exchanges, the <math><mi>s</mi></math>-channel nucleon and nucleon resonances exchanges, the <math><mi>u</mi></math>-channel nucleon exchange, and the generalized contact current. The latter accounts effectively for the interaction current and ensures that the full photoproduction amplitude is gauge invariant. It is shown that all the available CLAS data can be satisfactorily described by considering the <math><mi>N</mi><mo>(</mo><mn>1520</mn><mo>)</mo><mn>3</mn><mo>/</mo><msup><mn>2</mn><mo>\u2212</mo></msup></math>, <math><mi>N</mi><mo>(</mo><mn>1700</mn><mo>)</mo><mn>3</mn><mo>/</mo><msup><mn>2</mn><mo>\u2212</mo></msup></math>, <math><mi>N</mi><mo>(</mo><mn>1720</mn><mo>)</mo><mn>3</mn><mo>/</mo><msup><mn>2</mn><mo>+</mo></msup></math>, <math><mi>N</mi><mo>(</mo><mn>1860</mn><mo>)</mo><mn>5</mn><mo>/</mo><msup><mn>2</mn><mo>+</mo></msup></math>, <math><mi>N</mi><mo>(</mo><mn>1875</mn><mo>)</mo><mn>3</mn><mo>/</mo><msup><mn>2</mn><mo>\u2212</mo></msup></math>, <math><mi>N</mi><mo>(</mo><mn>1895</mn><mo>)</mo><mn>1</mn><mo>/</mo><msup><mn>2</mn><mo>\u2212</mo></msup></math>, and <math><mi>N</mi><mo>(</mo><mn>2060</mn><mo>)</mo><mn>5</mn><mo>/</mo><msup><mn>2</mn><mo>\u2212</mo></msup></math> resonances in the <math><mi>s</mi></math>-channel.
