Confirming that tiberium self-grows without any cutting.
Tiberium alone is inert, you can leave it out and it won't do a thing, however, if you leave it in a sim's inventory, your sim will eventually get a sick moodlet and the tiberium will change, becoming grayish and emiting radiation; after a certain time passes, it'll transform for free into a large spire cut tiberium.
Photography:
Photography at lvl 10 isn't as bad as it initially appeared for money-making purposes. It can support a wealthy family and even surpass painting.
In sunset valley / riverview, once you complete the architectural eye challenge, you can make 800-1000 simoleons on the first pic (half for the second) from each unique landmark with the "new today" thingy.
There is: park, bistro, dinner, spa, theatre, city hall, bookstore, grocery, library, gym, beach, school, mausoleum, stadium, hospital and places in town. My photographer sim can take a jog around town (train athletics) and make 15k simoleons in little less than 4 game hours. By going in car or by using teleporter+horus, these 15k could be obtained within an hour with ease.
You can probably also catch a car, sims around town, two is company, a bicycle, furniture, outdoor stuff, picnic, bathroom, hobbies, garden-related pics and other miscellaneous subjects; if you're lucky, you'll also be able to catch top career sims going to work and a limo, this would mean additional 1~3k per day. If you are in a multi-sim home with several family members, you could add another 500~2000 on top of that as well. Add in a whole lot more money from pics to travel stuff and relics (i wonder how much one can get from a canopy jar collection each day).
If you also have, say, a mummy in your home or a playable ghost mummy, well, money goes upwards again.
Of course, that is on the home city, on vacation, landmarks give stupidly high amounts of money. My first pic of dragon cave was about 11k.
PD: you also get 4-8 wishes per day to take photographs with specific filter/sizes, the beauty of this is that they're triggered by taking a photo of the subject in question, so you can complete them right away and cash in good amounts of happiness.
