  1. To administrators: How can I delete my entire account on photo.net?

    I did not find anything here about how to do this. I tried to delete

    my contributions one by one (they are many, so the action seems time

    consuming), but even so, I can't do it. Every time I push "delete"

    confirmation, I get "request error" message and nothing happend.

    Thank you.

  2. Hello,<br><br>

    1) From you experience, how powerfull a modeling light should be? I

    saw that most of the studio flashes have either 250-350W or ~650W

    (at theirs maximum flash output, or modeling turned at 100%). When

    do you need 650W of modeling light? And when 250W is simply not

    enough?<br><br>

    2) Wouldn't be a 650W of incandescent light too hot for the model

    or/and photographer? I have a 500W tungsten light and I feel it like

    a small Sun at several meters. In the summer I'll sweat because of

    it if the climate control is off.<br><br>

    3) How the 3200K modeling light is not "contaminating" the white

    light of the flash tube (~5600K)? The flash durration is very short,

    usually 1/400-1/1500 seconds, which is way too short for an

    incandescent light to shut down. The filament has to cool down to

    stop emitting light. The problem seems more severe if you set the

    flash

    power low and the modeling light to 100% (not prop.).<br><br>

    Thanks for the responses and sorry for this quite long list of

    questions.

  3. Hi,<br>

    How many watts per second (Ws, or Joules) have a Canon 550EX

    speedlite at 105mm head zoom and full power (1/1)? According to

    Canon, the guide number in these conditions is 180.<br>

    I found on the WEB an AC salve specification in which is stated:

    "Guide number GN: 36 (80 watts per second)". If the conversion Ws

    <-> GN is linear, then 550EX would have... 400Ws, which seems a

    little bit too much to me. :)<br>

    Thanks for responses.

  4. HP5+ in Xtol 1:1 is a great combination: wery fine grain and good

    details. However, the advertised time (12min @20C) is way too long

    for resonable contrast and density. After several experiments, I

    found 9min @20C being the right time to me.<br>

    No experience with Diafine.

  5. Hi,<br><br>

     

    I need two powerful monolights (>1000 Joules each) for product and

    portrait photography. After some search on the WEB, I found the <a

    href="http://www.patersonphotographic.com/lighting/combilight1.html">

    Paterson Interfit Combo Pro 1200</a> monolights to be affordable,

    having all the features I need, and taking inexpensive

    accessories.<br><br>

     

    Since I couldn't find any opinion on the WEB, does anybody here have

    experience with these monolights? Any information about flash

    duration and color temperature? The producer is not specifying these

    parameters, and the color temperature is an issue to me, since I plan

    to use slides too, not only my 10D.<br><br>

     

    Thank you.<br><br>

  6. Jayme, just because I wrote my belief after yours, it doesn't mean I referred to you. Or you just tried to victimize yourself a little? (<i>"you must be talking about people like me"</i>, <i>"I'm an idiot I guess"</i>)<br>

    As for the rest of your message, it's just an off-topic and pointless attack so I'll don't spend my time arguing with you.<br>

    Have a good day.

  7. Well Ivan, most of the photos here are so manipulated in PS because they are extremely lousy in original, and the photographer think that by putting a large amount of digital work he/she will get a better picture. If the viewer is used to do the same or have a limited visual culture, this may actually works: a bunch of 7/7 and WOWs will come soon for a photo which have nothing to show but color saturation (often understand as "good light" or "drama") or collages without idea presented as straight photos. People like lies - that's the answer to your question.
  8. I like a lot Ilfosol-S with Ilford FP4+ or TMax100. Very, very fine grain and low contrast.<br>

    Avoid it for high speed films, ISO 400 or more. HP5+ is grainy in it, and Tri-X 400 almost unusable (huge grain and density).<br>

    As a beginner, I would recommend you HC-110. It's a very flexible developer, and the concentrate syrup will last forever.

  9. I would skip both Velvia (too contrasty and saturated for an "all around" film, and also horrible for portraits) and Kodachrome (little exposure latitude, muted colors, hard to find a processor for it in most countries).

    <br><br>

    All I would take is Provia 100F as regular film and maybe some Sensia 400 for low light, handheld shots. As above stated, you may use 81A filter if Provia 100F looks too blue to you (actually this film ISN'T cold or blue, but looks so when compared to Velvia's yellows). Also, when "Velvia 50 look" is needed you can use Provia 100F with a warm polarizer - a polarizer combined with 81A or 81B in a unique filter. Pretty close...
