Why Can't I Take Pretty Pictures?
So if you find out the secret to great screenshots, please let me know.
Get one of the lighting mods to really pump up the dynamic lighting in the game, you'd be astounded how much of a difference that makes.
Try different camera angles and zoom levels to really highlight what it is you're trying to take a picture of.
If it is Sims you're modelling, try to download some poseboxes and pose your Sims before taking a picture.
You can also make a room better lit before taking pictures.
Just some thoughts
Thumbnail shot: You need to think about how big of a thumbnail you are allowed by the site you post to/graphics ability etc and make a thumbnail that is attention grabbing. Small thumbnails (150 by 150 or so) - NEVER have text. Unless its a mod.
Fanseelamb is the queen of thumbnail shots in my opinion.
Atmosphere shot: This is where you get to go wild. Make a setting for your item, something that shows why it is an awesome item and MUST be downloaded to a game. This is my fave shot.
Information shot: This is the MTS shot Make sure that people see what they are getting. You can make an info shot pretty.
PERSONALLY - I think my Move Over Dahlen set on MTS holds all of those shots and it is not a bad set at all. Though I think I may have written on the thumb. Bad fish.
