At first I would like to say, that my intention is not to hurt anyone personally or make fun of anybody's photography skills. I try to offer some alternative solutions to common mistakes. I have made many of these top 10-mistakes myself, and I have learned from them. And of course everyone has their own taste, and who am I to disagree on that?
10: Raajojen sun muiden ulokkeiden amputointi/Amputation of the limbs
You don't need to fit the whole person/target to the photo, but there is this one ground rule; don't cut the limbs. Elbows, ankles, knees, neck... etc.
9 ja 8: Epätarkat ja heilahtaneet "taide"kuvat/unfocused or unstable "art" photos
By focus, you want to show what is the main thing in the photo. I don't believe you if you tell me that the coat rack or toilet seat behind your head is that. By moving the camera fast, you can give the effect of speed, falling or movement etc. But shaky self portraits only tell of acute lack of caffeine.
7. Turha kuva, vintage-filter ja Helvetica-teksti/Ugly photo + vintage filter + Helvetica
I think this is some kind of hipster thing. If you have a dull photo, there's no saving it with fancy filters.
6. Muovinen photoshop-naama (+duckface!)/Plastic face(and also duckface)
Duckface nyt on jo varmaan niin itsestäänselvyys, ettei minun tarvitse edes perustella, miksi se on valokuvaajan turn-off.
By blurring your face you end up looking like weird plastic toy. Instead, you can remove tiny flaws with healing brush, spot healing brush, stamp tool or clone stamp tool, for example. I would like to point out, that skin pores, tiny wrinkles, skin's natural texture or moles are not flaws.
I believe I don't even have to start on what's so wrong about duckface...
5. Turhat makro-kuvat/Pointless macro photos
Congratulations, you just found the macro possibility on your camera's menu. Now you can photograph raunchy close-ups of your music player, cellphone, lemonade bottles and table corners!
4. Ruuat ja vintagefilter/Food and vintage filter
Instagram is full of "what I ate today"-pics, refined with some kind of vintage photo filter. Ground rule: If the photo itself isn't that interesting, It won't be interesting after heavy touch-up either. And also I would like to point out that when you photograph food, never use blue colors or lighting. It makes the food look yucky. One should highlight the food with warm tones, like yellow or red (depending on the food).
You don't want the photo to consist of one huge limb that reaches to the looker. It's super creepy. It also tells that you're not familiar with the self timer. In this photo we get the wrinkly forehead-bonus and also a vague duckface-bonus!
2. Turhat sensuurit/Pointless censorship
If you have a photo where your nose looks like a piggy's snout and your boobs loll out of your shirt, Don't publish it. Take another one, better. Cover your boobs. Your nose's fine. If you don't want your breasts to form a cleavage, don't squeeze them together. This kind of censorship is ridiculous.
1. Peilikuva salaman kanssa!/Mirror image with flash!
Why... Why? And that same pose, always! Why! *cries blood*. If you have gotten your hands on a fancy system camera, this is practically a rape. It's not very hard to use self-timer or manual settings. The flash makes the mirror look dirty as fuck. You can make your own camera stands practically from anything, like shelves, book piles or chairs.
Personally I'm quite bored of these overly photoshopped "this is my eye"-closeups. A good photographer gets inspired, gets influenced, gets excited... But never imitates. Make up something that's your own thing. Approach things from a differend angle. Think about how you could execute an average picture in some completely new way.
