An image sensor pixel for use in a high dynamic range image sensor includes a first photodiode and a second photodiode. The first photodiode include a first doped region, a first lightly doped region, and a first highly doped region disposed between the first doped region and the first lightly doped region. The second photodiode disposed in has a second full well capacity substantially equal to a first full well capacity of the first photodiode. The second photodiode includes a second doped region, a second lightly doped region, and a second highly doped region disposed between the second doped region and the second lightly doped region. A first aperture sizer is disposed above the second photodiode to limit image light received by the second photodiode to a second amount that is less than a first amount of image light received by the first photodiode.
