What you say makes sense.
But how about those of us who are practicing and wanna make sure we wanna get a good shot?? As @ times we're not so sure yet as to what we're doing and are not able to see well from the shots thru LCD what is good composition, exposure or what not until uploaded on a computer ?? :unsure:
Advises of photography workshop facilitators is to always carry an extra memory card. Another advise is to get as much pictures that one can after pre- setting composition, aperture, ISO, shutter speed settings- compare all the shots so given the chance next time to do similar shots, one knows already in mind what works well.
Well I can sense your concern that I am putting pressure unto you. I don't want to do that. I don't want to purvey that I am showing off (that is the not what you call professionalism) or to demoralise you or say what you've been told is wrong (there is no rights or wrongs in photography). As for learning its better to learn what you want out of your photography.
The best thing as this video says about photography is the attitude and not about the ability to take photos
