If you’d like to stick to the 35mm format and need it to be an ISO 200 film, you may look towards Kodak colour films like ColorPlus (review: analog.cafe/r/kodak-colorp…) and Gold (review: analog.cafe/r/kodak-gold-f… — BTW, Gold and ColorPlus are almost identical: analog.cafe/r/kodak-gold-v…), Portra 160 (a premium, finest-grain colour-negative film in this range: analog.cafe/r/kodak-portra…), or the new Kodacolor 200, which was launched yesterday: analog.cafe/comments/q6zh (and is now sold out practically everywhere).
