    Is there a major difference between RGB prints and wet printing.

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    When you scan film or slide, you lose a bit of quality.

    However digital printing offers more flexibility than analog printing : color correction, sharpening, selective dodging/burning, manipuation, etc. So, you gain quality compared to analog printing, because all these thigs that were really time consuming and hard to do become accessible.

     

    So, depending on the technologies and techniques used, and the operator skill, you may gain in digital printing more than you lose in scanning, and get an awesome result. Or not.

     

    It's hard to compare prints because there are so many factors, it even includes how many hours of sleep the operator had the night before ;) or if you fall in love with the look of a certain process...

     

    You're the judge in the end.

    About warranty for 5D

    86000 shots for $760 repair is about 0.88 cents per shot... or 113 shots per dollar... if you calculate it that way it's reasonable...

     

    I know it sucks when stuff breaks, but how much would film have cost ? how much money did these shots earn you ?

    Backing up data, how much, how often?

    RAID doesn't replace backups but it's so convenient when your harddrive dies and all the annoyance you get is a mail saying "your harddrive has died, please replace it". You don't have to spend a day reinstalling the OS and everything.

     

    I grew tired of DVDs. They are cheaper than harddisks, but if you add up your own time to burn them, and the inconvenience, the unreliability, they end up not being worth the trouble.

    Data Recovery Company Recommendations

    Hehe. I had a good laugh when I saw that "product". Who would buy this ? Raid 0 offers no reliability. Using this is asking for trouble. I'm really sorry for you. I think selling that kind of crap is near criminal. The docs don't even say "RAID0". Of course they don't say "if one of the drives fail, you're hosed".

     

    Anyway. From what you say, I assume what is burnt is the LaCie board, and not the electronic board from one of the drives. This is logical : a company daring to sell an external raid 0 solution like has absolutely no respect for customer's data and thus must also use the cheapest and lowest quality components possible.

     

    In that case the drives are probably alright.

     

    In that case, go to the store, buy an identical enclosure, transfer the drives to it, plug, it should work. Copy your files somewhere else and return the enclosure you just bought for refund. Throw away your LaCIE crap.

     

    For the future :

     

    I just assembled a 1 terabyte RAID5 array on a linux box out of 5 x 250G disks. You can mix sata and pata, plug them in any slot and order you want, when one fails you replace it, and besides, the cool thing is it just works. (and it saturates the PCI bus, at about 120 MB/s read speed). Also, there is no RAID controller, so RAID controller failure can't happen. And if the motherboard burns I can plug the disks in another PC, boot knoppix from the CDROM and get access to the data. And it's cheaper than the big LaCIE...

    What is internal focus AND is it bad that lens doesn't have it?

    in Canon EOS Mount

    On a prime (non-zoom) lens Internal Focus is nice because the lens length does not change as you focus, thus you don't have to be careful as to where you put your fingers (as opposed to the 50/1.8 which is not IF, and changes length during focussing, which can be surprising if your finger is on the moving part).

     

    Also the lens body can be better sealed against dust as it does not change size. Super pro zooms also have internal zoom, which permits good sealing, as opposed to the standard zoom whose pumping action will suck in air and dust everytime you use it.

    Is Leica glass TOO good?

    Well, the job for an enlarging lens is different than for a picture taking lens, for instance :

     

    - Your camera lens might have to deal with a huge contrast range (think : sun in the picture) and must be flare-proof ; an enlarger lens only has to deal with the neg's density range, which while quite large for B&W, has nothing in common with what the camera sees. Thus enlarger lenses don't have such a critical need for über-multi-coating.

     

    - An enlarger lens must reproduce a flat negative on a flat paper. Thus it must not have any field of view curvature. In a camera lens, this matters only if you take pics of flat subjects (like reprography) , thus the two are usually optimized for different factors.

     

    - Both lenses must keep their qualities from their closest to longest focus, but the focus span for the enlarger lens is a lot smaller.

     

    - A good camera lens has to be optimized for bokeh, while an enlarger lens does not. For instance it can have less disphragm blades.

     

    - As long as you can see your film grain being rendered sharply from edge to edge in the loupe, I guess your enlarging lens will be sharp enough.

     

    Just a few thoughts...

    Digital vs. Film

    Also Gold 100 is a film optimized for exposure latitude and flashy colours so that :

     

    - you can over/under expose quite a lot it and still get something printable : it can work even in the crappiest P&S, even if it is a fixed-focus one-use camera...

     

    - the average P&S user gets nice flashy colours.

     

    But it's got rather strange colours, personnally I don't like it at all, it tends to make blue sky like fluorescent cyan, and has other funky color saturation issues also. It's nice for night shots, though, because of that. Try Fuji Reala or Portra VC or Supra if you want nice, lush colours, but in a more realistic, pleasing way.

    This is off-topic, but :

     

    A hard drive is cheaper than your free time ! So buy several and make backups !

     

    I'm setting up a RAID5 box to hold all my important data. Don't buy all your drives from the same batch/manufacturer. Don't store them in the same location. Be paranoid. Harddrives die. Houses burn. Computers get stolen. Digital can be backed up, unlike slides, so use that !

    Nice design, clean, fast gallery, not using flash : all these are very good points.

     

    Basically your site shows that a properly done HTML/Javascript gallery will beat a Flash gallery anytime, and that's good, because we have seen too many slow, stupid, un-ergonomic flash galleries by now.

     

    I would like thumbnails instead of numbers though. Why not put a column of thumbs instead of the column of numbers ?

    Lugging around a truckload of equipment to go street shooting isn't really that practical, I'd simply suggest to spot-meter the highlighted part of the face and place it at +2 stops above middle gray point, in a pseudo zone-system fashion, and shoot raw. Fill flash could have been used, but the lady on the right would have been blown out.
