hello, recently i shoot in super bright sun (on foma400 ) and i noticed some bad light leaks. on the weekend i have an important shoot but dont know which holders it were. Plus its pretty gloomly lately so i cant leave the holders in the sun and see light leaks on the film, would i get same resolut flashing the film holders with 500ws strobes? could i identify the bad apples like this? thanks alot!

<p>thanks!<br> what confused me today was that the agitation method worked perfect on an expert drum i had.<br> <br />but rotating the jobodrum in bathtube of temperated water makes sens!<br> but should i rotate all of the time or in the same manner as i was agitating<br> ...<br> by pouring water the jobo tank to fill the sheets it takes 1,3 L<br> which is too much chemicals for only 6 sheets i think and i also think that 1,3L of developer is too much for the film.</p>

<p>i got a Jobo drum 2521 and today i made my first development in this drum.<br> i was agitating with hands and i put 300mm developer but at the end 1/4 of the sheet was very poorly developed, like there was not enough chemistry in the tank..<br> is there any advice about hand agitating and how much developer should there be inside of the drum?<br> or is this drumm made only for machine rotation? bc. it says that min is 270mm</p> <p>any ideas?<br> http://i63.tinypic.com/bdjsqc.jpg</p> <p>thanks alot!</p>

2.7 -3.5.., I'm afraid to go higher to screw up the actual dof, when i want the swirlynes of 2.7 so I cleaned the glass, looks gery good, but outside its still very hard to get the focus right when the subject is far away. normally i focus on eyelashes, so i have the contrast, but mybe asking the model to put something contrasty on her face would help? but whaat?

what would weak photoflo solution be? how many drops into how many ml of wather? thanks!

yes! loss of contrast is also a big part... mybe i should also stop down abit while focusing? thanks!

its a top viewfinder pacemaker. how to clean the groundglass? just alchohol? thanks!

this will be mby a silly question, so im sorry for it. but: lately ive been shooting alot of LF, and i just got a 165mm f2.7 lens. and I'm have big problems focusing if the subject is far. the speed graphic viewfinder is too grainy if magnified alot. would better groundglass help? or a better loup? or some special tehnick? ps. for loup i use my pentax 67 magnifier viewfinder and cheep loup from a shop.

<p>hello!<br> i have a question about Thorium in Pentax 67 system<br> i know that Thorium is in the old 105mm f2.4 lenses, but somewhere i was reading that it also might be in the gals of the eyepiece magnifier, the prism viewfinder and the other view magnifiers ...<br> anyone has any info on this?</p>

<p>was doing a bit more reading and some one on another forum suggested it is corrosion...</p>

<p>hello..<br> i have an Epson v700 in top condition since 4 years and the pattern you can see you the pics was there since i got it from the shop. i didnt mind back than because it didn't have an effect on the scans, but as i was reading i read it might be fungus some days ago..<br> or is it just Scaneritits? :)<br> <br />its only on the plastic that drives up and down, the glass is perfect, so im wondering.. is this fungus?<br> is it bad? and is it possible that i will spread on my other camera lenses?</p> *i attached a pic<br /><br /> <p>thanks alot!<img src="https://img2.brain4.photobox.com/35930897e09f69be5f0d8b9015bfe4253e90d9472d5e5a6f32e523cd16e7b9abf426901b.jpg" alt="" /></p>

<p>hello!<br> i got an offer for 2x Bownes espirit 500<br />in apparently good condition, with 2 stands for about 400$</p> <p>it doesn't say much on the condition, but it should be good and working...<br> since this models are pretty old (how old is the espirit model actually?) is it worth buying old studio flashes?<br> the bulbs should be good the seller says...<br> lately i was ripped off few times buying 2nd hand gear (i dont have the $ to buy new)<br> so is there many things that i should be careful with when buying old flash?</p> <p>thanks!</p>

afaik coverage is not an issue, i read it easily covers 6x7, i was referring more to if some of the models of the lens are a no go, bc it was a bad batch, or bad glass used. thanks :-) forum.mflenses.com/mod-your-p6-sonnar-180-2-8-for-pentax-67-t49391.html

i found a option to buy this lens and modify it for the use with Pentax 67, but since i saw that there are different versions of this lens, is there anything particular i should be checking? or are some of the version a no go? thanks!

<p>i having quite bad luck with all of my cameras lately.. so tomorrow i make a test shoot and see...<br> but damn it happened twice in a row after the focusing screen change and i never had focus problems before</p>
