    as others have said, you can create a larger (say 2x2) mosaic and do software emulation of the perspective correction functions. Emulation the focus-plane effects will be MUCH harder.</p>

    <p>You may also be able to get a pano head and software solution for well under $400. First off, Hugin is one of the best stiching software solutions and is open source freeware. It's powerful and fairly easy to use. For 180x360 stiching especially, photoshop and cannon's software WON't do it, there is too much mathematical remaping/warping that needs to be done, and you want a specialized program.</p>

    <p>As far as heads go, I use a panosaurus, which is only $80. Granted, its not as stable as the $400 heads, but it is stable enough that i've had good success with xt and the 24-105, and overall I'm very happy with it. I'm not sure how well it will handle the 5D2 w/ 24-105. (FYI, an inverted ball head won't work, you'll get massive parrallax issues.) I'm assuming you already have a decnt triopd?</p>

    <p>My advice would be to take a flyer on a the panosaurus or other 'entry level' head, and see if you A) like pano photography and B) NEED something heavier duty.</p>

  2. Edward-I think your understanding is off here, or atleast confused by another brand.

    Fuji uses L, M, S to differentiate actual pixel dimensions.

    They use "Fine" and "Normal" to distinguish different levels of JPEG compression.

     

    see the "File Write / Display and Sizes" heading under this review:

    http://www.dpreview.com/reviews/FujifilmF31fd/page4.asp

     

    To the OP--Memory cards are cheap and its easy to batch resize in post processing (google faststone photo resizer)., I would shoot at Large Fine at all times, you never know when you'll get a keeper. You will not gain anything by having you're camera downsize the photo off the bat. You may be thinking of the (still conceptual?) idea of pixel binning, in which the camera treats 4 pixles as one pixel to improve noise/DR. However, your camera doesn't do this, its just resizing a jpeg and gives you no benefit.

  3. Very interesting thread on prehaps one of the most intriguing new aspect of digital photography.

     

    I think Edward nailed it on the head when he said:

     

    "You only notice HDR when it's done wrong." and "For others, HDR is a tool you use on location so you don't have to lug lights around, but the ultimate goal is to get normal looking images."

     

    There will always be people taking pictures of their old junker in the front yard, over HDRing them, and throwing them on flickr/myspace/deviantart and call it edgy art. A few years ago it was oddly composed, oddly focused images converted to high contrast black and white and thrown on F/MyS/DA and called edgy art.

  4. I take it you have the old 18-55 (non IS version). The new IS version is reportedly much better and costs about $180, I haven't used either but it might be worth getting opinions on.

     

    I don't own, but have used, the 17-40. Its a great lens! Others with more experience can comment further, but it seems like it would be a good replacement for you kit lens, although maybe a little short (but you've got the 50mm)

     

    Have you considered the 17-55 f2.8? its a stop faster and has IS but is ~$300 more. I do own this lens and love it.

  5. I am only posting this in the Canon forum because it?s the one I frequent the

    most. I think this would be applicable basically every forum on the site.

     

    Has any thought ever been given to creating a "Sticky" type of post to address

    some of the most frequently asked questions for a particular forum? Something

    sort of halfway between a true article and a post? Almost all of

    these "popular" questions ("70-200: Which one?", "Will my old XXX brand lens

    work with the XTi", "Is the $300 5D on SuperCameraDeals.com real?", "Which

    lens for sports?") seem to get rehashed on a weekly basis. I?m sure most of us

    who have been around here any amount of time can begin to anticipate responses

    with out even opening the thread!

     

    Clearly, a lot of these questions are answerable by using the search or

    reading existing articles, but sometimes people are new to the site,

    overwhelmed by search results, etc. Also, people who have been around long

    enough to know where to find articles, probably have seen many of these

    threads already, so a very basic FAQ in the form of an article would probably

    not be that helpful. Newer users tend to gravitate to the forum; I know I did

    when I was new. For example, Philip has a great overview/review of the

    different 70-200s, yet how many times do we see "Which 70-200 should I get?"

     

    Maybe there is a way we could have 4 or 5 posts that are sort of like

    a "journal review", like an overview or survey of all the posts relating to a

    certain frequently asked topic. In one sense, they would be more of what this

    site considers articles, however, there wouldn?t be much editorializing, it

    would basically be a synthesis of opinions posted on the topic in other

    threads, specifically responding to the common questions. It would be

    different from an article or review, however, in that it would permanently be

    fixed at the top of list in the forum.

     

    I am not an expert on any of the questions frequently asked here, but I am a

    believer in action: I would be willing to edit and synthesis the first of

    these hybrid article/post, if it can appear as a sticky type of thread.

  6. I'll share a funny story about SF and photostores. I was there this summer, and went to the middle of nowhere (tourism wise) to buy an EF-S 10-22 from Calumet the first day I was there because, obviously, I wanted to use the lens on my trip. I got down to the Fisherman's Warf area, and saw what is probably your same Discount Photo. As I was walking past (With my 24-105 on camera) the employee who was out on the side walk calls out to me "Hey, I've got a nice new lens for your camera there" and I go "No thanks, I've got all the lens I need!". I saw in the window they had the 70-200 2.8 IS for something like $2,750.

     

    Anyway, if you truly feel you were ripped off (not that you just over paid) and paid by CC, I would def. contact the card company. What does your recipt say the return policy is?

  7. Most of the effect comes from dodging and burning. Im not sure what your level of PS experience is, but basically it selectively darkening/lightening of areas. <br><br>

     

    For instance, on your third link, the wheel ruts have pretty obviously been dodged (made lighter). So have parts of the bushes, and the very white parts of cloud. <br><br>

     

    PS has dodge/burn tools but the best way is to do it with adjustment layers and masks. <br><br>

     

    see Nigel Nagarajan's response on this thread

    <a href="http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=00DcgJ">http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=00DcgJ</a>

    <br><br>

    It has a good explanation of using layers/masks for D/B. Also, now that you know what its called, you should be able to find some tutorials on the web.

  8. Jeff just a note on your comment:

     

    "In an attempt to avoid blown highlights I use the histogram on my 20D and watch for the flashing areas to see whether I have achieved a 'good' exposure...."

     

    The flashing highlight blown indicator on the LCD is based upon the JPG not the RAW, if you take a second exposure and over expose by 1.5 or 2 stops and STILL get the flashing areas on your LCD, then you've truly blown those areas in the original shot. If not, the raw will should still have detail

  9. the only "problem", at least with the canon lens, is that you are paying for and carrying the weight of a full frame coverage lens, but not "using" parts of it. Whether or not this is a Problem or just a "problem" depends on your feelings on the issue.

     

    For me, it wasn't a problem. I use a 24-105 as my primary lens on a 350D and don't mind the weight. The cost sucked alittle, but remember you are essentially "cropping" out the worst performing parts of the lens, its corners which makes the average IQ of the lens higher.

     

    I don't know enough about the tamron 100-300, sometimes these older lens need re-chipping/have compatibility issues. i have no experience with this lens so some one else will need to chime in.

  10. that would def. be neat. It is intereting that with both usb2 controllers and wi-fi USB adapters being comodoitized price-wise that we haven't seen a generic adapter that would fit any camera, screw into the tripod mount battery grip style, and attach via a short USB cable to the camera's port, and interface to your wi-fi with the controller USB.

     

    I'd hack one up if I knew how to progam a controller to handle it.

  11. Diane-

     

    You can make multi level panoramas as well! if you are using a X and Y axis pano head and have set up the nodal point you could make a top row of 3 shots, then a bottom row of 3 shots, and stich it in a 2x3 pano. Max Lyons uses this technique with a 200mm lens to get gigapixle sized images... think 20X20 panoramas! <a href="www.tawbaware.com/maxlyons/">www.tawbaware.com/maxlyons/</a>

  12. I am getting ready to purchase a new machine and am looking for

    recommendations on a company to go with. Im fed up with the "big box", Dell,

    HP, etc. due to their lack of flexibility on processors, OS, options I want

    (RAID) only available on "super" systems, only a few graphics card options,

    etc.

     

    I am looking for something like the old alienware (before they went big box,

    and not specializing in gaming machines), where you have more flexibility, but

    they will take care of compatibility issues, actual assembly, etc.

     

    PC USA (http://www.pcusa.com/) looks promising and sort of what I am looking

    for but I have not been able to find anything pro or con on them. If any one

    has any recommendations, I would appreciate it.

     

    Dave
