This room looks a little dark. Start by turning on the light switch. The boot on the floor looks like it might be of use, examine it more closely. Get the card from the boot and use it on the TV screen. A refreshing soda might be nice, or an item in the mini bar might be relevant to the investigation. Use the hand icon on the small refrigerator. Take the batteries from the minibar and put them on the camera. Now you can get the film out of it. The director has, conveniently enough, set aside part of his area as a dark room for your use.
You need to find a way to replace the red burn out bulb.Take the filter from the minibar and use it on the empty syrup bottle on the floor. Use the filter on the bulb in the nearby lamp. Great, now you have a red bulb. Use this bulb in place of the burnt out bulb in the darkroom.
You need to develop the wall. Read the note on the wall to figure out how to do this. Start by using the wrench on the faucet. Fill the sink with water. Dip the print in the black bin, the sink, and then the white bin. Use the enlarger and repeat the bin process. Pick up the clothespins on the floor and use them on the clothesline. Place the prints on the line. Finally, use the blow dryer to dry off the prints. You’ll see that the director has been taking pictures of a snake tattoo on the shoulder of the actress.
