Which Macro Lens to pick?

[Roomka]

hello, Im currently using a 60MM macro lens And thinking of getting a 100MM. Here a a picture with the 60MM. Will the 100MM be a better choice? thanks.

you probably wont notice anything that different other than you dont have to shoot it as close.

 

[Roomka]

yeah i keep the lens maybe like 6 inches away from the watch. plus i wouldnt want to move further away from the watch due to the small room i have

 

[Robin Usagani]

it wont be that much farther LOL.. just like a few inches.

 

[Roomka]

yeah. but you see the picture i posted the left side of the face is a lil off focus, i use F18 And if i go lower it will worsen. But then again if i go higher it will get better but the quality drops after f18. What can i do to fix this issue. i use a nikon d5100 right now but was thinking of buying the Mark III 5D today

 

[Robin Usagani]

Move the camera back a little. Depth of field is greatly controlled by the distance from the camera to the subject.

 

[Roomka]

niceee, thanks alot!

Focus stack. Get a focus rail and use some free software like CombineZP. Also, before I did anything else, I'd work on that lighting and exposure.

Why would you switch systems? You will have to buy all new lenses to match! You can increase your DOF by backing off (distance) a little more. You can then crop the image to show what you want if needed.

yeah my lighting is kind of dark because its the way i like to work on photoshop, these watches have sometimes a brushed finish and not a shiny finish so when i take it with 0 exposure compensation it looks all shiny. this way i can control what parts needs to be brighten up
<- this would be with 0 compensation. Compensation with 3 bars to the right->

 

[cgipson1]

Still very underexposed.. assuming your brighten in photoshop?

 

[Roomka]

yeah i do, what can i do to fix my exposure settings?

Are you metering? What are you metering? Spot metering is the most accurate for this type of shooting... but you have to remember that the meter actually meters for gray! Put a small gray card in your lightbox, and meter on that... lock that metering in with your settings in manual. Recompose, and shoot.

You are obviously using constant lights (or ambient) with your shutter speed at 1/30.... we see exposures like this all the time with constant lights.

Camera: NIKON D5100
Software: Adobe Photoshop CS5.1 Windows

Focal length: 60 mm (equiv. 90 mm)
Aperture: F18
Exposure time: 1/30"
ISO speed rating: 200/24°
Program: Manual
Metering Mode: Pattern
White Balance: Manual
Flash: Flash did not fire

with flash, you could shoot at 1/250, F18, and a lower ISO. Sometimes with a long exposure, you can start getting more noise... as the sensor heats up...

 

[Roomka]

yeah im not metering because i dont know how to use it, do i leave the gray card for the rest of all my shoots or is the gray like a one time background setup?

Check out Rolex site and try to think about how they lit their watches in their images. I'm not 100% sure but I think most high end watchmakers photographers create composites of the same shot, each with different lighting and then combine them in post. What I mean is they don't set up the lighting for the whole watch. They light individual areas of the watch seperately and combine in post. This way they can control the specular highlights and apparent light size for each individual area of the watch like the face, glass, edging, band, diamonds, etc.
