getComponent requires that the requested component 'BloomQuality' derives from monoBehaviour or component or is an interface

im trying to get acces to the script 'Bloom' that is type 'PostEffectsBase'

. using UnityEngine; using System; using UnityEngine.UI; using System.Collections;

namespace UnityStandardAssets.ImageEffects { public class GRAPHICCONTROL : MonoBehaviour { public Slider bloom; public Slider shafts;

     // Update is called once per frame
     void Update()
     {
         SunShafts shafts_Q = GetComponent<SunShafts>();
         Bloom.BloomQuality bloom_Q = GetComponent<Bloom.BloomQuality>();

         //bloom
         if(bloom.value == 1)
         {
             bloom_Q = Bloom.BloomQuality.High;
         }
         if (bloom.value == 2)
         {
             bloom_Q = Bloom.BloomQuality.Cheap;
         }
     }
 }

}
