Noise Reduction - Canon 7D and ISO 3200

Question: "Shiv, do you do much post-processing on images shot at ISO 3200 with your 7D? I have many such photos from our Costa Rica trip and wonder if I can improve some a little by reducing "grain"."Response: When you shoot at ISO 3200 you need to process using Canon's DPP for the initial Noise Reduction before you do any work in Aperture, Lightroom or ACR. Now you can bring the images into Photoshop and use NIK's Define if you have it or use the noise reduction in Adobe Camera Raw for further noise reduction if required - I find Define to be about the best.
