Hi Mallesh, In Photoshop if you convert into B&W you can choose contribution from each channel (RGB) for conversion. Choosing the component which is rich will give you brighter tones (in this example I assume you have green grass there). In Photoshop, choose, image -> adjustment -> channel mixer -> monochrome & green channel. Hope that will work for you..
