Taking Better Model Pictures: Fun with f-stop!

[Guiddy]

I know I have to increase the F-Stop or aperture to get the focus across the full length of the model, but that seems to give this pinky washed out look!
You guys who take good photos, how do you do it, namely Lau bak and the guy who has the Digital hobby site!

Here is a normal pic, the camera set to auto, and an F-stop of about 2.4.

Notice how the front is out of focus, but the colour good!

Now with this one, the field of depth is better, an F-stop of 5 is used, but the colour is washy now!

Well, I don't know much about taking photos of car models. but you want to match up your f-stop (apeture) and film speed with the lighting. If you're doing this outside, (which I'd do since you get the full spectrum of colors) put your f-stop on 5.6 or whatever is closest. then mess with your film speed. normal speed is 125 or 250. The more light you have, the higher that number. The less light the lower the number. Find the light meter (off to the side when you're looking through the lightmeter) and match up the wand (your current settings) with the light wand (how much light is really coming in). If you match those up, you should have good range of colors and good focus.

Note: If you decide to take a photo on a speed of 60 or below, you have to be really still. But the camera on a desk or something elsewise (I know it ain't a word!) the picture gets blurry.

If you're using a digital camera, then take as many photos as you can. It's not that expensive afterall. Standard camera's are more expensive. It's a lot like modeling, the only way you really figure out how do something is to do it yourself.

Changing the f-stop is not your problem. One of two things is going on here. Either your exposure is wrong in the second photo or the printer just duffed the printing. It's kind of hard for me to tell which.

Look at your negatives. They should all have about the same density. If not, your exposure was different. If they have the same density, the printer screwed up.

Shutter speeds and f-stops have a 1:1 relationship. As you close your f-stop one stop, you change your shutter speed one setting slower.

Your camera's light meter should handle that for you just fine. I see nothing in the photos that should through the light meter off. Did you have a partly cloudy day when you took those photos? If so, you could have taken one while the sun was obscured by clouds and the other while the sun was uncovered. While the density overall would be the same, the hightlights would be brighter.

Your best bet is to shoot in "open shade." IOW, the car is in the shade, but light by diffuse light from the sky. That will give you even lighting.

I could probably tell you more, but I'd have to look at the negatives unfortunately.

Taking another look, it looks like it may be a combination of two things.....

It looks like indeed it was a partly cloudy day. The washed out photo appears to have more defined shadows under the car.

The other is that I think the printer just blew it. You should have it printed darker. I think that would solve the majority of the problem.

I should state that those pictures were taken with a Fuji film 4900 Zoom 4.3 megapixel digital camera.

It has full manual control, so most tips can be carried across from SLR to Digi.

I'll have a play today...

Thanks for the tips guys!

It appears to me that the second picture is over exposed. Since F is increased, the speed has to be shortened, isn't it?

So I need to speed the film up or the shutter speed?

I don't think I can adjust the shutter speed on the camera, one thing is adjusted and then the other compensated if you see what I mean!

I can change the film speed though!

And I see you have updated your site! Superb, that will keep me occupied for the next hour!!!

How far from the subject is the camera for those pics, Guiddy?

[Guiddy]

About 10 inches! Manual focus too!

Wow! I think I'm going to go steal my dad's SLR camera. My automatic camera won't even let me take a pic from less than 4 feet!

I found another site with some pretty good photos to drool over:

Look at the engine on the R390!!! Wow!

[Guiddy]

Another site for the list of favourites!

Some nice kits, and a good collection!
The R390 comes like that from Tamiya, some great stuff!
I have a transkit for mine which makes the detail out of this world, but a bit daunting!
One for a week off work I feel!
Nice one Jay, I enjoyed that!

I think you've set a wrong white balance. I can see the whole pic was in a blue tone, especially the second one.

I usually use small apeture (mainly F8 for me) and auto shutter in sunlight. Manual setting of white balance is very important too. Those auto setting suck. A reflecting board can always be helpful there.

Photoshop is a important final stage, too. I used to blur the background and adjust the light effects.

Oh I forgot to say, the background choice is most important. But how? Just imagine you are the man with 2 inch in height, and look at the BG!

I don't think I have that much control on my digicam! It isn't bad, but it isn't THAT good!
