For the image of the yellow pointed orchid, I used Flexible Smart Filters, in Photoshop, as they are non-destructive. I first converted the image in to a smart filter and then added the Gaussian Blur filter to blur the background. I then used the free mask to hide the effects of the blur around the point to keep it as the main focus in the photo.
The image of the sunrays originally had a under exposed foreground and so I used Adjustment layers in Photoshop to lighten this. I choose the Screen Blending Mode to lighten the entire image, and then used the mask to reveal the original background. I also added a slight Flexible Vignette Boarder to frame the image.
