Author 'Jacques.marcandelli' (Id 187237 ) : For the previous photo I had pushed the sharpness to the maximum by telling you that it was possible to keep for example a background blur. Therefore, starting from the same series of photos, but taking only those which are net from 0 to 30 cm, it is possible to obtain the orchid very sharp and let it blur the foreground and background. To obtain this effect it can be interesting to do more tests : take the pictures from 1 to 29 and 1 to 30 and 1 to 31 and select the series that gives the best compromise between sharpness/blur. For already select the last photo in 'useful' (30 in my case) it is possible to look visually in each photo to estimate its sharpness.
