  We present here three recipes for getting better images with optical
interferometers. Two of them, Low- Frequencies Filling and Brute-Force Monte
Carlo were used in our participation to the Interferometry Beauty Contest this
year and can be applied to classical imaging using V 2 and closure phases.
These two addition to image reconstruction provide a way of having more
reliable images. The last recipe is similar in its principle as the
self-calibration technique used in radio-interferometry. We call it also
self-calibration, but it uses the wavelength-differential phase as a proxy of
the object phase to build-up a full-featured complex visibility set of the
observed object. This technique needs a first image-reconstruction run with an
available software, using closure-phases and squared visibilities only. We used
it for two scientific papers with great success. We discuss here the pros and
cons of such imaging technique.
