- camera sensor cleaning -- there's such a thing. you need to know how it's done. or find someone who can do it for you. marunong daw si marty sabi ni skip :)
- fungus can develop on the lenses. i already know this, but nearly not doing anything to prevent it. tsk tsk. i did more research and here's what i found:
Keep your lenses in a dry, cool place. If you use your equipment in damp environments, let it dry as soon as you return into a drier room. Never leave your equipment in a closed (splashproof) camera bag when it need not be there. Leather lens cases are known to be especially bad, because leather is a natural product where fungi can grow before they proceed on to the lens. Synthetic materials are better, but there is no guarantee there either.
If you store the equipment in a sealed (air-tight) case, adding a small bag of silica gel or other absorbent may help. You will need to monitor the status (usually a change in color of an additive) regularly. As soon as the gel shows signs of saturation with water, it should be replaced or dried. Otherwise the process will reverse, and instead of drying the case, it will add moisture to the air and make things worse.

- i really need to buy those silica gels now because my bag of gel (which i know to be expired by now) could already be reversing the process. yikes. time to visit the handyman.
- how to tell if the "dirt" is on the sensor or on the lens itself. you use a different lens or change focal length then shoot several photos. observe. if the position of the "dirt" does not change with differing focal length, "dirt" is sitting on the sensor. if position changes with differing focal length, then "dirt" is on the lens.
- if there is dirt on the lens, have the lens cleaned by the service center. cost could be around P500 per lens.
- we need to keep humidity from 40 to 60 within our storage boxes to prevent fungi from infecting the lenses. for this i need a hygrometer. cost of a digital hygrometer is P800. Analog is P400. The box can be an air-tight Lock & Lock container. You can buy all these at SM. Digital is better.
- the new canon 450D is out. it has live view (yehey!) and costs $900. i think i will also save up for this.
- how to setup lights using the following: light stand (around P700), umbrella holder (around P800), umbrella (P700), and external flash. very easy. point the flash towards the umbrella and let the light bounce. the umbrella is lined with a silver material which reflects light better than white surfaces do. need to save money for these equipment.
- shooting portraiture with external flash is better than built-in flash. definitely already know this from the time i bought my vivitar flash, but i didn't know how hard having an external flash would be compared to placing that flash in a light-stand and a reflector-umbrella! life is just so much easier when the flash is on the stand and light is being reflected by the umbrella as opposed to having the flash attached to the camera and bouncing light off the walls or the ceiling. with flash attached to the camera, you start having problems the moment you switch from landscape to portrait or vice versa! you will have to re-adjust the flash each time... and the camera gets heavy and blur may most likely occur! im sure it takes getting used to, but at the start, its so cumbersome. moving forward, use light-stands for portraitures.
- do not trust your eyes and the LCD in gauging whether exposure is good. LCDs can be deceiving. inspect histogram and/or buy light meter. or assume that you need to "over-expose" a little if you know that your LCD tends to brighten things up for you. experiment.
that's it for now... i feel that there's a few more.... when i remember them, ill definitely share them. in the mean time, happy weekend and happy shooting!
