I would like to have some help with to dark or to light pictures

[Raz3rt]

Hi, I am new on this forum because i just started a month ago with taking pictures.
In life i am a web- developer & designer and it wasn't a bad idea to also start taking my own pictures (mostly products) an bought myself a basic Nikon D3200 with a Nikor 18-105 lens with 2 daylight lamps bought here: Linkstar FLS-3280SB6060 Daglichtlamp met Softbox 3x28W | Daglichtlampen | BonjourFoto.nl. I have a small room where i have installed a white paper to take my pictures.

- When i am taking these pictures on the preview screen of the camera some are looking very good but then if i put them on the computer they are to dark or the background is more yellow even if i stand there and look it is really white?! (i do not us my flash because this shines into the product).
- When i took some pictures of products with a mica (plastic) around it the lights are very much reflecting in the mica (plastic). Are there any trick to stop the reflection (believe me i have tried everything i could and know :blushing.

I provided this pictures in an attachement. I am very sorry they are still in the normal size but otherwise there would be some down sampling and than i cannot show my problem anymore..

Last: I have allready tried to play with ISO, Shutter & Diafragma but like i told at the beginning i am still practicing with my manual and a book for the D3200 in my other hand.

Could anyone have some tips around this? When i take the same products outside then i have to say it is much better! But in Belgium it is sometimes raining to much .

Thanks for the help

Being too dark is a product of not enough light. Higher ISO might help, longer shutter speed, or wider aperture. That or brighter lights.

As far as color, different lights produce different color temps. An incandescent bulb will give you a warm or reddish light. You can either change your white balance in camera to fix this or do it in post. It's easier to get it right in the camera.

As far as reflections, that's due to the position of your lights. Moving them at different angles or using gobos (go betweens) can help this along with a polarizing filter depending on the type of reflection.

The book Light Science and Magic is great for explaining these principals.

White balance for the lighting problems and I saw a recent post where the person said use white or black poster board just off scene. You can't stop the reflections so you control what is reflected - the poster board.......

Both shots look like you have lighted the background more than the subject. Bring your lights more to the front and arrange more white paper (not plastic) to reflect the light onto your subject. These two photographs have different colors of background, and I think you want white for both. This can be fixed on the computer by adjusting the white balance. Make sure your camera's white balance is set for the type of light that you have.
