Why is there quality loss on my image styles? This is the original image (610x405)



This is the image after applying image style (scale and crop) to 290x190.



Both image have the same aspect ration, yet there is visible quality loss on downsizing. Am I applying the right image style? What should I be doing?
Under admin/config/media/image-toolkit there is an option to set the JPEG quality. By default this is 75%, so you should be able to up that to whatever you want.
