comment How do you organize your photos before you shoot them?
@KartickVaddadi: in that case, you can have one folder for experiments and another for everything else. Later in post, tag based on folder and then additionally tag based on date + checkin information as described in #5. I also added another option #6 above

comment Can we measure size of an object using EXIF data from a photo?
@TFuto: Actually, my bad. both of your equations are the same ... the brackets don't matter. I think I got confused since I was thinking in terms of object width and your equation is in terms of the entire image width. In this case it makes sense as long as sensor_x = (width of the sensor in m) and pixel_cnt_x = (width of the sensor in pixels).

comment Can we measure size of an object using EXIF data from a photo?
@TFuto: you have it wrong. sensor_x in your case is in mm, not pixels. Converted to pixels, it is sensor_x = pixel_cnt_x*total_sensor_x/total_sensor_px_x

comment How do you determine the acceptable Circle of Confusion for a particular photo?
Circle me confused. Is the Zeiss formula for print size or sensor size? What if you have a 100% crop of an image? What is the acceptable CoC for viewing on screen?

Oh .. and the focal length should also be squared

comment Can we measure size of an object using EXIF data from a photo?
The equation is wrong. Why 2x? You are calculating an area, therefore, it is squared. It should be distance^2. See photo.stackexchange.com/a/12437/7292

comment How to improve sky's saturation and contrast to get a similar result?
@Revious ... Cont. ... With front lit scenes, you will not get as much pop in the clouds without the aid of a circular polarizer. About golden hour, it is the time of day with best light for photographs. Normally within an hour past sunrise and the again before sunset. Thats when the sun is really low and creates nice soft golden light (look at the rays on the cat). Your shot is done with a harsher light when the sun is higher up.

comment How to improve sky's saturation and contrast to get a similar result?
@Revious back light is exemplified by the cat shot. The light illuminates the back of your subject. Front light is the opposite where the light source (sun in this case) illuminates the front of the subject as in your picture. Now, back lit scenes are much more difficult to photograph, but they would usually produce a greater dynamic range when done right as in the cat shot. The light in your shot is much more even so the dynamic range will be naturally less. Also, with backlit clouds, they normally pop as the light goes through and around them. This is how you get those nice peaking rays
