Yup, dulu wa tak pakai flash, lagipun wa tak pakai tripod. Wa punya aperture pun terlalu besau.
This time wa pakai tripod, pakai flash, aperture set to F8, speed about 1/40 to 1/80.
Sometimes my monti starts rtn, then grow again, then rtn again, then regrow.... I also not sure, may be it's like that when the kH or other parameters fluctuate.
