First, I brightened the image by duplicating the layer and setting the blend mode to screen. I did this seven times and merged the layers. This fixed the exposure, but it left the flowers over exposed. To repair that, I went into shadows/highlights and set the shadows slider to zero and the highlights slider to maximum, reducing the exposure for the highlights and pulling a bit more detail back into what had become blown out. Then I created a selective colour adjustment layer to bring out the colour of the bee. However, this changed the colour of the plants as well, so I created a layer make to limit the effects. Then, deciding that the bee was a little too dark, I duplicated the background layer and used levels to make it brighter. Then I created a layer mask and copied the layer mask from the selective colour layer onto the new layer mask.
Oh, and I cropped it too.
