This year was one of the best wildflowers blooming years at Rainier. I was so waiting to process this shot and finally got some time yesterday.
To get depth of field like this, you would need a focus stacking technique to stack multiple shots focused at different point in frame and stacking them in software like Photoshop. This shot is made from 3 shots for wildflowers, 1 for mountain and 1 for sky with lower exposure settings. After blending, some curve adjustment and o/p sharpening and re-sizing for FB.
