Product of very poor quality. The Neutral Density filters give a horrible magenta Long exposure, operation of the photo, even trying to correct the white balance, becomes impossible..Je strongly discourages. Meter as much money directly into more expensive but better quality filters.
Products of very poor quality. The neutral density filter give a horrible purple color impossible to work on post treatment. I recommend to expend more for better purpose filter, and above all, not to buy this product.
