I am totally satisfied with this mémophoto, light and compact, which is a valuable reminder, easy to use, especially when shooting conditions are difficult: sunny scenes contrasting portrait against the light, stage life inside without a flash, night photography, river or waterfall blur, etc ... I also bought the second memo Anne-Laure Jacquart (The composition step by step) which is also a wealth of valuable advice. Since I bought these two books I'm improving every day, with ease, the quality of my photos.
