Best Macro for Photographing Paintings
Posted By Dubesor

Hi everyone,

I'm looking to buy my dad a present of a new Pentax lens that he can use to digitize artworks. I understand that macro lenses are considered to be the best for this because they are flat field and have minimal distortion. I've done a bit of art digitizing myself on my Nikon with the Nikon Micro Nikkor 60 for a friend's exhibit with nice results.

My question is which macro between the current DFA 100/2.8 WR, DFA 50/2.8 Macro, or the DA 35/2.8 Macro? Price wise they're all in the same range, seems like all three are on sale at B&H. So far, I'm leaning towards the DFA 100/2.8 but I have a few things I'm not sure about. Maybe some of you know?

* Crop factor / shooting distance - Is the 100mm long for the APS-C crop factor? I forget which exact camera my dad has, but I think it's a K20D or K200D. The works he'll be digitizing are in the 20x20 inch range. I'm having a hard time visualizing what the shooting distance would be to fit a work like that in one shot on 100mm APS-C (or 50mm or 35mm).

* Distortion / Sharpness - Among the macro choices, would the 100/2.8 have the least distortion, be the most flat-field, and have the best sharpness, etc?

* Other applications - A side consideration is other uses of the lens. I think my dad could use the lens I get for other things, for example the original macro purpose, portraiture, landscapes. It seems for actual macro work, 100mm is a better choice because you can shoot from a little further away (especially for small moving subjects)? And reports say DFA 100 2.8 macro is a strong portrait performer. What situations do the DFA 50/2.8 Macro and the DA 35/2.8 Macro shine at?

Handheld Meter Purchase?

I will take all the advice into consideration. Thanks for writing in!

I also think the iphone route may be a good one - perhaps with this attachment: Luxi Light Meter Adapter for iPhone 5/5s Review - photo.net

I'm not a total beginner with slide film, I have loved working with Velvia in the past - here are some scans Velvia Film Scans - a set on Flickr. I just want to get better at exposing for it when I do use it, as it's got a lot less exposure latitude than color negative film.

I will be trying to choose and buy a meter today to receive it in time for my trip.

Handheld Meter Purchase?

After shooting for 5 years without a light meter, I'm starting to think I really need one to nail my exposures. Especially for slide when I'm shooting slides. I'm looking for a meter that will be reliable, relatively small, and easy to use in the field. Oh, and economical :) Recommendations from those of you who use handheld meters all the time?

I'm going on a trip soon where I'll be using a Rolleiflex or Pentax 6x7 alongside - and often instead of - the digital K5 II. I don't want to rely on sunny f16 rule though it mostly worked for the last trip when I brought only the Rolleiflex (some samples Rolleiflex - a set on Flickr) . And I'm not sure I can rely on just taking a reading from K5II's built in meter (or any camera's built in meter) and dialing it into the Rolleiflex or P67.

Are there any advantages to getting a brand new meter vs slightly older selenium ones? Maybe easy LCD readout? Do any new meters have the ability to transfer the reading directly to the K5ii? I know some of the Canikon equipment works this way (at least for flash?) ...

is this the lowest it has dropped in a while? Or is it in the $1000 range regularly?

K-5: Exposure Approaches

I think that's another major bonus of underexposing. I was doing a few test shots and was able to stay on ISO 80 even in a dimly lit room at night, with the exposure compensation dialed into -1 EV.

K-5: Exposure Approaches

This makes sense to me intuitively. I've never managed to make corrected highlights look great, if they were blown at the time of the exposure. The detail hardly comes back in Lightroom, yet I've definitely seen the unsightly color casts and tonality issues you mention. This is based on my experience with earlier Pentax DSLRs, but it sounds like it's similar on the K5. Anyway, I'd be much happier if slight underexposure was the "textbook" approach instead of ETTR.

Any other people? Do you overexpose and correct highlights or underexpose and pull shadows?

Can you fill me in? What is the new slider called in LR4? Or is there a whole other workflow?

And what's your approach for recovering detail in the highlights? I always found Lightroom's Recovery slider kind of meh (this is probably also renamed in LR4). Photoshop's Shadows/Highlights tool has been a little better, but not much.

(p.s. awful pun intended)

I just got myself a K-5 (the original model). I've been wanting one for a while. The $740 price is quite a steal for this camera, I think.

I'm interested in how to get the most out of its great sensor - both at the time of shooting, and later in Lightroom. Having spent the last few years shooting medium format film, I'm a little rusty with DSLRs (though I've owned a K-x, K20D, and K100D in the past). So I'd appreciate some tips ...

1) Pulling shadow detail for maximum DR. From reading others' posts, it seems there's a lot of extra shadow detail contained in the K-5 RAW files. A common approach to maximize DR seems to be shooting at the lowest ISO possible (80 preferably), underexposing a bit, and then bringing the shadows back in processing. Is that as simple as giving the RAW image more "Fill light" in Lightroom - or are there special tricks to this? Share your techniques

2) Taking good advantage of the high ISO. With the K-x, overexposing in-camera to about +1 EV was a good rule of thumb to get ISO 6400 files with little perceptible noise. Is that more or less the same on the K-5?

Thanks!

well, i'll pretty much never be leaving my cameras / film in a car on this trip.

but it might have to be out in the sun on my back in my daypack - on the days when i'm passing through without a room to stay in.

i think i'll bring a drink cooler bag like this one - but not sure if that'd help much for those situations?

I'll be travelling in Puerto Rico for a month; it's going to get quite hot - as much as 35C sometimes and lots of sunshine (I hope).

I plan to bring 50-60 rolls of 120 film with me for this trip and would like to make sure I'm protecting those rolls correctly.

Maybe some of you have tips to share from similar voyages... How did you keep your film cool? And is it such a big deal if it overheats sometimes?

I wonder how accurate it is for metering in the 4-8 second shutter speed range (and slower)? Ever try metering for these long-ish exposures?

(I often use ISO 50-100 films and stop down to f8-f11, which means multiple seconds even in broad daylight)

i did a little bit of testing outdoors today and it seems to meter well for my DSLR (K-x) anyway.
i'll do more testing tomorrow with the medium format camera.

6x7 Lenses on 645n & Stop-down Metering Trouble

Good advice all! I'll try keeping the lens switch in MANUAL instead. For some reason, I thought it had to be AUTO (maybe based on M42 Takumars I used before)

Pretty sure it's been stored in darkness for the last 10 years or so; i found it inside a pristine camera case bought at a thrift store (it contained a lot of other goodies - like the Takumar 85/1.8)

6x7 Lenses on 645n & Stop-down Metering Trouble

I've had an exposure disaster on a recent photo trip that was quite disappointing. I want to make sure it won't happen again.

I was shooting with my Pentax 645n and two lenses - the native 645 FA 75/2.8 and the 6x7 Takumar 55/3.5 (using the Pentax 6x7 to 645 adapter).

The 6x7 lens overexposed a lot when stopped down. I haven't had this problem shooting wide open. On the other hand, the 645 lens produced correct exposures with the camera's built-in meter, as always...

Just to confirm, to use stopdown metering, I should keep the camera in "A" mode and flick the switch on the lens to "AUTO"?
I did that and stopped down: the metered shutter speeds got progressively longer which seemed OK (but turned out very inaccurate at smaller apertures, as I mentioned).

I have an old light meter I haven't had much occasion to use... but now I'll need to make sure it's reliable - I'm going on a month-long trip to Puerto Rico and lots of my photography will be done using a Yashica-Mat and my Pentax 645N. I use 6x7 lenses on the latter and the camera's built-in meter is often totally off when I stop those down. The former doesn't have a built-in meter.

The meter is called Sekonic Auto-Lumi, like the one here:


How can I double check it's metering fine? Forgive if it's a dumb question - If I were to use this meter's readings on my Pentax K-x DSLR and the exposure seemed correct, would it still be correct for my film cameras?

PS The only time I did use it, for one roll on my Edixa Reflex, it seemed to underexpose somewhat. Here are some drugstore scans from that roll: Flickr: Search dubesor's photostream

Does anyone on here have real-world experience filming with both a Pentax K5 and Canon's 5D Mark II? I know they're different classes of camera, but I'm curious whether one has menus/controls in video mode that are a lot better than the other?

I'm contemplating a DSLR system for producing a small film; would love to do it on a Pentax, but a bit concerned - the model I use now (K-x) has a pretty poorly thought out video mode...

Oh I see what you mean ... I think that was natural to me for some reason. Next time around, I'll try centering these people in the frame and see how that looks.



Two of the three lenses were AF. With those, I used AF-A mode with the "Select spot" (the one that looks like a honeycomb). I used the centremost spot.

Shooting event assignments on my DSLR takes me a bit out of my comfort zone. (mostly doing fine art projects on medium format film these days - and those images rarely involve people)

Anyway, I've shot several events for a client of mine. Each time, my technique and delivered images get a little better (I think). I still feel like maybe some things are lacking and could always use some advice and constructive criticism ... so if some other pros or semi-pros have time, weigh in :)

http://flickr.com/gp/dubesor/y96535/
Here are the proofs - you can view each one at 1000px (click on thumbnail, then click again on the image when it loads).


For this gig, I used my K-x with the F 50/1.7, FAJ 18-35, and M 100/2.8 lenses. Kind of silly selection, I know, but gotta work with what I've got (sold off a lot of my 35mm gear, including the FA 50/1.4).

I feel like my AF lenses missed focus a bunch of times ... what do you think? But the high ISO on the K-x is fantastic - I didn't need a flash.

PS I'll also be posting proofs from the 2nd day of this event, when I used only the DA 35/2.4 and also shot 2 rolls of film on my Pentax 645.
