When you say "employed" do you mean that you are actually an employee of the company? If that's the case then they would already have your SSN and I'm not really sure what the purpose of an invoice would be.

If you are doing this as an independent business, then Federal Income Taxes are between you and the IRS. I've never put my SSN or Tax ID Number on an invoice and can't remember ever receiving an invoice with a SSN on it. The only time you need to give another firm your SSN or Tax ID for Federal Income Tax purposes are those instances where they will be issuing a 1099.

ND filter vs Photoshop

Buddha, it has been a long time since I was at the Grand Canyon and perhaps there is now less air pollution. However, the filter I used the most was a polarizing filter. It did a great job of reducing the haze caused by light reflecting off of particles in the air. People were often amazed at the difference between what they saw when viewing with the unaided eye and looking through my viewfinder. (So yes, there are things that a filter can do that photoshop can't.)

The choice between using a ND Grad and HDR may boil down to which one will work under the circumstances. It's not like both are always an option. If there is enough breeze to move foliage--the ususal case where I photograph most of the time--then HDR is very difficult. On the other hand, using a grad is difficult if the light/dark separation isn't a fairly straight line.

If I remember correctly, the canyon rim is usually flat enough so that a ND Grad can usually be used if you are including both sky and canyon. On the other hand, moving foliage won't be a problem on distance shots. Hey, it's the GRAND CANYON, I'd want the entire tool box at my disposal.

This may not really be as silly as it sounds. Some large format photographers have become very adapt at translating what they see in a Polaroid to what they need to do in the way of exposure and lighting to get the image they want on film. Using digital as a preview may seem logical, but there is no reason to believe that a Polaroid and digital respond to light in the same way.

While I wouldn't want to work that way, I believe that you do whatever works for you. If this is getting him the images he wants then I would certainly understand his reluctance to change. It's the image that counts, not how you got it.

Domke Camera Bags

I have an F2 that is several years old. It's a well made bag that I could recommend to anyone. One reason I like it is that it is fast to get into and encourages camera use. I hate bages that make you jump through hoops to reach your equipment.

I think it would hold your gear although I don't know how much room your flash takes up. According to some old literature I have, when Jim Domke designed the bag in 1976 he needed it to hold the following: two SLR 35mm cameras (one motorized), a 17mm, 35mm, 85mm, 75-200mm, and a 300mm f/4 as well as a flash and other misc. items.
Wow, I not sure I could get mine to hold that much.

I doesn't seem to me that items placed in the outside pockets have that much protection--just a layer of canvas. Also, it looks to me like the snaps that holds the cover down could hit equipment if you are not careful, but I've never had it happen. I leave the top unsnapped much of the time and have little worry about a spill because of the way it is designed.

Donít get me wrong. I love my Pentax 67. It just seems like some of the digital photographers on this forum seem to obsess about the number of features a camera has including those that most people would seldom use.

. . . and, I almost forgot.

There are probably as many films for large format than there ever was. In fact, I'd have to dig through "View Camera" magazine, but I think some have been introduced just recently. Also, according to "View Camera", some new film developers are now on the market.

They might be hard to find now, but someone used to make an inexpensive plastic bag that hung and you could dry the film inside. However, it doesn't take long for film to dry and if I can do it here in West Texas with all the dust then you can probably do anywhere.

A bathroom is a good place if you have one that can go unused while your film drys. If you are really worried about dust you can help clear the air by turning a hot shower on until it produces a little steam to settle the dust down. I rarely feed the need to do that.

I pretty much agree with the above posts. Film will still be around for a while, but it may not be as convenient. I now order medium and large format film from B&H. The local camera store doesn't stock b&w in those sizes although they do carry some color. The owner is a good friend and would order it for me, but I can order it from B&H just as easily.

Great images, FireMate. The tone values are stunning. Iím impressed! I presume the slight vignetting was intentional since it works so well with the photo noir style. What lens did you use?

Many believe that the 67 (6 x 7, 67II) isnít suitable for handheld use. Obviously at least some of you that have responded would disagree. I was once surprised to see a very petite oriental girl use one for street photography. (With a wooden handle attached it probably would make a good weapon.)

Ninety-nine percent of my exposures are made using a tripod. With a slow B&W film I wind up with many exposures in the 1/2 to 1/15 range, especially when using filters, and I think I experience is some shutter vibration at these speeds unless I use a fairly heavy tripod. Of course, under these conditions mirror lock up is essential.

I certainly have nothing against digital and, in fact, feel liberated when I can stick on a zoom and handhold my K10D. However, I seem to produce my best work when I go into a ďcontemplative modeĒ with the 67 or, occasionally, a 4 x 5. Since I like to bracket and explore different compositions, the 4x5 is pretty much reserved for those situations when I know exactly what I want. Also, Iím getting old and lazy.

Sorry if this has been covered already, but the recent post about medium format cameras had me wondering if there were many Pentax 67 users on this forum. Iím here because I have a relatively new K10Dómy first serious digital cameraóand wanted to know more about it. While I love using (and handholding) the K10D, my favorite camera is still the Pentax 67.

The Pentax 67 is a quirky, clunky camera that is almost totally lacking in bells and whistles but has an almost cult-like (albeit small) following. Iím not that familiar with the newer 67II, but consider the following limitations of the 67:

--no interchangeable back

--film loading can be a little clumsy until you get the hang of it

--no self timer

--mirror lockup is almost a necessity

--slow flash sync (1/30 sec) except with the more expensive leaf-shutter lens

--heavy, although not as heavy as the Mamiya RB or RZ

--only 10 shots on a 120 roll

--a relatively heavy tripod is needed, especially at shutter speeds around 1/8, to dampen shutter slap.

Could someone whose only exposure to photography was a digital camera ever love a camera like this?

I love the Pentax 67 but I certainly wouldn't recommend it if you are limited to what you can travel with. It's not just the camera and lens, but you'll most likely need a heavier tripod than what you are currently using with your DSLR.

I have hundreds of negatives that I made with a Mamiya 645. I would bet that you can get into that system at a decent price, especially if you don't need AF. I just prefer the 67's larger negatives and, in most cases, I'm willing to carry the extra weight.

I can highly recommend the Epson R2400, especially if you think you might want to print any B&W. While I use it for both B&W and color, it has pretty much replaced my B&W darkroom. I know three or four other photographers that also have one and none have had any problems with it at all. It will print 13 inches by 44 inches with roll paper, but I have only used the 13 x 19 sheets.

Do you use Hyperfocal distance ?
Posted By jmax

It is important that people remember that DOF charts and lens scales are based on some assumptions regarding viewing distance, print size and etc. The results should be considered a general guide only.

The Cambridge in Color tutorial appears to be a good source, I also have a DOF calculator and tutorial at:

DOF Table W/Definitions

There is a javascript calculator there that will probably work with Windows but might not work with Mac OS X. However, for those with Excel, there is a download link there that includes a DOF chart (and other tools) that include a digital format.

http://www.fineart-photography.com/PhotoTools.xls

Finally, there is also a tutorial about usings the DOF scale on a lens barrel at:

Using DOF Scales

It should be noted that on a lens designed for 35mm the scale will not strictly apply to a digital sensor that is smaller than 24mm x 36mm. DOF charts assume that for any given focal length the same size print will be made no matter the format. In other words, the smaller the format, the more it has to be enlarged and, consequently, focus become more critical.

In looking at DOF charts for different formats it might appear that digital cameras are at a big disadvantage DOF wise. However, a digital camera can capture the same scene with a shorter focal length than the film formats and DOF is greater for shorter focal lengths.

Thanks for your input guys.

Regarding the conversions, I'd probably be one of the last you'd want to ask since I'm pretty new at it. I've used earlier versions of Photoshop, but right now I'm just using Elements and conversions consists primarily of using a Hue/Saturation layer to desaturate and lighten or darken the different colors.

As far as correcting the distortions via Photoshop, if doing so will have the same effect on sharpness as it appears to have in the above example, then I don't really think it would be an option considering the size prints I'll be making.

Current B&W Project

Iím primarily a B&W photographer and I'm currently working on a project that involves photographing grain elevators in the northwestern Texas area. This is my first attempt at using my new K10D instead of medium and large format film for something like this. I havenít decided yet, but these images may be part of an exhibit that will go up in September.

Iíve always loved seeing these structures when traveling across the Texas Panhandle and Plains. You can see them miles away and there is almost a surreal element because of their immense size relative to their surroundings. This surreal element is part of what Iím trying to capture in my images.

To get the images I want usually requires getting fairly close to the subject and using a wide angle. Of course, this is going to result in considerable lean and tilt of the structures. If I were concerned with capturing reality I would have used my Sinar 4x5 (and shot color), but Iím now wondering if the distortions may be too distracting--especially in the horizontal images. They donít bother me and, up to now, I havenít worried about them but . . .?

Duke, my Weimaraner, has been unimpressed so far and thinks we should get back to the regular outdoor stuff.

Here are some example shots from the project.

Pentax File Folder Icons for Mac

My computer desktop is usually petty messy with file folders scattered everywhere. Sometimes I make file folder icons to make a folder stand out. If you have a Mac and are interested, here are some Pentax camera icons I made while waiting on call to come through:

Pentax File Folder Icons

You are free to use the link there to download them and use them as you see fit. I'm sure Mac users know this, but you just drag them out of the folder to your desktop, change the title, and use them just like a regular file folder. Of course, you can duplicate them if you want more than one.

I did only 5 folders because that's all the cameras I had photographs of.

(based on the horizontal dimension of the actual image area--69mm x 56mm)

Incidently, the 1.5 magnification factor, an unfortunate term, is based on the horizonal dimension also. The Pentax sensor is 23.7mm and the 35mm film is actually 36mm or 1.52 times the Pentax sensor. Some think a diagonal measure should be used instead of the largest dimension.

A good illustration of angle of view and film/sensor formats can be seen at:

If you have Excel, you might be interested in downloading a workbook I made available some time ago. It has some a lens conversion worksheet as well as some other stuff on it.

Go to:

Tools for Photographers

A 90mm lens will provide a 23 AOV for a 35mm, a 41 AOV for a 6 x 7 and a 15 AOV for a Pentax DSLR.

A 31mm lens on a Pentax DSLR or a 48mm lens on a 35mm would be the equivalent to a 90mm on a 6 x 7 in terms of the image it would capture.

But a 90mm lens is a 90mm lens regardless of what camera it is on :-) So, it you put a 90mm lens on a Pentax DSLR it would be the same as a 135mm on a 35mm.

This should be enough to confuse almost anyone.

You will most likely need a tripod for the Velvia. For 35mm I like Ilford Delta 400, but if you are not going to develop the film yourself you might use Ilford XP2. I usually rate XP2 at 250 or 320 to make sure I get shadow detail.

If you intend on putting the Loch Ness monster in any of the images you will probably need to scan the film or switch to digital so you can use Photoshop :-)

Matthew,

Your site looks much better. I appreciate the way you have considered suggestions without becoming defensive the way many would have.

I think the number one requirement of a photography web site is that it doesn't distract from the images. As far as I'm concerned, a clean presentation with simple and obvious navigation pretty much gets you where you want to go. Now you can concentrate on the enjoyable part: making images.

Matthew,

I enjoyed looking at your site. I never know whether people that ask for input on an image or website really want critical input or are just looking for compliments. However, since you probably know much more about computers than I do, Iím not going to cut you any slack just because you are only sixteen :-) Iíve been interested in looking at sites lately because Iím trying to get around to updating and redoing mine. (Mine is certainly not an example of what a good site should look like, but I do have a little experience with marketing.)

I really think that uniformity and continuity are important. While your home page is seems OK, there is somewhat of a jarring transition in going to your gallery pages. The style is completely different and I think that this distracts from what you are trying to accomplish. On the other hand, I like the simple and obvious navigation. The exception is the ďPortfolioĒ link which leads to a 404óat least link it to something before you ask people to look at your site. (Remember, I said ďno slackĒ!)

I like the idea of having a link that explains the ďTexas Hill CountryĒ, but do you really want to invite people to leave your site just when they arrive at the home page? You may want to consider having this link open up in a separate window.

Most of what I might say about the gallery pages is pretty much nit picking. I like the simple navigation except maybe the ďUp a LevelĒ thing, but thatís probably just me. The thumbnails arenít always a big help in selecting the images to view, especially the night images at Lost Maples. Iím not sure how much trouble it would be to make them larger. I noticed that the frames you used varied from gallery to gallery but, while I would like to see more uniformity, I donít think this is all that distracting.

Anyway, these are just my opinons. I think it is probably better than many of the the personal websites I see. I had prepared my critique before seeing the previous posters remarks and there is some overlap. I'd certainly bet that he knows more about web design than I.

Well, the cost of living in general is higher in England than the USA. With the exception of just a few items such as bread and milk, almost everything (housing, clothing, electronics, gasoline (petrol) and most food items) is more expensive there. In other words, it is not just Pentax cameras that cost more there. I'm sure you already know that, but other's might think you were blaming Pentax.

How do I feel about it? I'm sorry you have to pay more and I'm glad we don't :-) While my background is in economics, the reasons for differences in the cost of items is not something I'd want to get into on a photography forum. It would be much too easy to drift into a political discussion and I'd like to think I'm smarter than that.

To answer your question about taxes, in my home state you don't pay sales taxes on items bought from an out of state store unless they also have a store in your state. For example, on an order from Adorama or B&H I only pay shipping.
